Composition of numbers to 9

This three-week unit deepens children's understanding of numbers 0 to 9 by exploring how each number is made up of two smaller parts. Children use ten frames, counters and part-whole models during continuous provision and small-group work to find how many more are needed to make 9, to partition 7 and 8 in different ways, and finally to find every way of making 9, including with zero. The unit links practical part-whole work to the idea of taking away, so children start to see addition and subtraction as connected. It builds towards eyfs.ma.number.1 (a deep understanding of the composition of numbers to 10) and eyfs.ma.patterns.3 (exploring patterns within numbers, including how quantities can be distributed).

Teacher notes: Composition of numbers to 9

This three-week unit deepens children's understanding of numbers 0 to 9 by exploring how each number is made up of two smaller parts. Children use ten frames, counters and part-whole models during continuous provision and small-group work to find how many more are needed to make 9, to partition 7 and 8 in different ways, and finally to find every way of making 9, including with zero. The unit links practical part-whole work to the idea of taking away, so children start to see addition and subtraction as connected. It builds towards eyfs.ma.number.1 (a deep understanding of the composition of numbers to 10) and eyfs.ma.patterns.3 (exploring patterns within numbers, including how quantities can be distributed).

eyfs.ma.number.1 Have a deep understanding of numbers to 10, including the composition of each number.
eyfs.ma.patterns.3 Explore and represent patterns within numbers up to 10, including evens and odds, double facts and how quantities can be distributed equally.

Key vocabulary

Common misconceptions

Children think that 3 and 6 making 9 is a different fact from 6 and 3 making 9, so they recount from the start each time the order of the parts changes.Use a physical part-whole model with two hoops: show the same two groups of counters, then swap which hoop is on the left and which is on the right, asking 'has the whole changed?' Let children see that the total stays 9 either way.
Children do not think 0 and 9 is a real way to make 9, because one part looks empty, so they skip it when hunting for ways to make 9.Model an empty part on a ten frame or in a hoop and ask 'how many are in this part?' alongside the full part of 9. Confirm with the children that zero counters is still a part, and that 0 and 9 make 9 just as 1 and 8 do.
When using a ten frame to find how many more make 9, children count all the squares on the frame rather than only the empty ones, giving a wrong 'how many more' answer.Ask the child to place a finger or a counter only in the empty squares while counting aloud, physically covering the filled squares first so only the empty ones are counted.
Children believe each number to 9 has only one way of being split into two parts, so once they find one pair they stop looking.Prompt with 'can we find another way?' and provide loose parts (two colours of counters, two trays) so children can keep rearranging the same total of 9 and record each new pair they discover, for example with photographs or marks.
Children confuse 'take away' with simply removing objects until none are left, rather than seeing it as finding the missing part when the whole and one part are known.Link directly to the part-whole model already used: show 9 counters, cover or remove one named part, and ask 'how many are left in the other part?' so take away is seen as finding the missing part of 9.

Assessing through observation

Assess mainly through observation during continuous provision and small-group activities rather than through recorded work. Watch whether a child can use a ten frame to say how many more are needed to make 9 without recounting from 1, and whether they can partition 7 and 8 into two parts using real objects. Listen for children using vocabulary such as 'part', 'whole' and 'altogether' during play, for example in the role-play area, small-world set-ups or construction. Note whether a child can find more than one way to make 9 when given loose parts, whether they include 0 and 9 as a valid pair, and whether they can respond to a simple take-away prompt by identifying the missing part. Capture evidence through photographs, practitioner notes and brief adult-scribed comments, referring back to each session's focus (ten frames, part-whole of 7 and 8, every way to make 9, number bonds including zero and take away) to build a picture of progress across the unit.

What comes next

The next unit moves on to the composition of 10, including finding all the ways to make 10 and relating this to key EYFS images such as the ten frame and double-sided counters. This leads into early work on doubling and halving within 10 and exploring odd and even numbers by seeing whether a quantity can be shared into two equal parts, continuing towards eyfs.ma.patterns.3. Secure composition of 9, including the role of zero, gives children the foundation they need to reason about 10 and beyond with confidence.

Ten frames: how many, and how many more to make 9

4 children · 15 minutes

Objective: Children read how many counters are on a ten frame and work out how many more are needed to make 9.

eyfs.ma.number.1 Have a deep understanding of numbers to 10, including the composition of each number.

Resources

  • 1 large ten frame (floor mat or tray with 10 spaces)
  • 9 double-sided counters per child
  • a set of printed ten frame cards showing 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 counters
  • a small drawstring bag
  • a soft toy to pass round

Set-up

Lay the large floor ten frame out on the carpet so all 4 children can reach it. Put the counters in the drawstring bag. Place the set of ten frame cards face down in a pile next to the frame.

Key questions

  • How many counters can you see on the frame?
  • How many more do we need to make 9?
  • How do you know without counting them all again?
  • What do you notice about the empty spaces?
  • Can you find two different numbers that make 9 together?

Vocabulary

ten frame, how many, more, make, full, empty, altogether

What to do

  1. Gather the group on the carpet around the large ten frame and show them 9 counters in the bag.
  2. Turn over the top ten frame card and ask a child to place that many counters onto the large frame, matching the pattern on the card.
  3. Ask the group to count the counters together, touching each one.
  4. Ask the key question: how many more counters do we need to fill the frame up to 9?
  5. Invite a different child to take that many more counters from the bag and fill the empty spaces until the frame shows 9.
  6. Say the matching number fact together, for example 'and make 9'.
  7. Empty the frame and repeat with the next card, passing the soft toy so a new child goes first each round.
  8. For the card showing 9, ask how many more are needed, so children notice that 9 and 0 make 9.

Misconceptions

A child recounts every counter from 1 each time instead of counting on from the number already on the frame.Cover the filled counters with a hand and ask, 'if this many are hiding, how many more until the frame is full?' to encourage counting on.
A child thinks the empty spaces must be counted in the same order as they were filled, so loses track of how many are left.Point to the empty row and ask the child to count only the gaps, touching each one, before adding counters.
A child believes a full ten frame always means 9, overgeneralising from this activity.Show a ten frame filled with all 10 spaces and ask the child to count it, confirming that a completely full frame is 10, not 9.

Part-whole: composition of 7 and 8

Small group of up to 5 children · 15 to 20 minutes

Objective: Children partition a group of 7 or 8 real objects into two parts in different ways, and match their partitions to a part-whole model, building their understanding that 7 and 8 can each be made of two smaller parts.

eyfs.ma.number.1 Have a deep understanding of numbers to 10, including the composition of each number.

Resources

  • A set of 8 identical real objects per child (for example conkers, pom-poms or dinosaur counters)
  • A part-whole mat per child: one large hoop (the whole) with two smaller hoops or paper plates inside it (the parts)
  • A drawstring feely bag
  • A small tray or basket to hold spare objects
  • The 13 part-whole model picture cards: 1 and 6 make 7; 2 and 5 make 7; 3 and 4 make 7; 4 and 3 make 7; 5 and 2 make 7; 6 and 1 make 7; 1 and 7 make 8; 2 and 6 make 8; 3 and 5 make 8; 4 and 4 make 8; 5 and 3 make 8; 6 and 2 make 8; 7 and 1 make 8

Set-up

Lay out one part-whole mat per child on the carpet or a low table. Place a basket of 8 objects next to each mat. Put the feely bag and the shuffled picture cards within the adult's reach.

Key questions

  • What is your whole number today?
  • Can you show me two parts that make your whole?
  • How many are in this part? How many are in that part?
  • Is there another way to split your 7 (or 8) into two parts?
  • If one part has 4, how many must be in the other part to still make 8?
  • Which picture card matches the parts you have made?
  • What do you notice about the parts when you swap them around?

Vocabulary

whole, part, makes, altogether, split, same, different way, swap

What to do

  1. Gather the group on the carpet and show everyone 7 objects in the whole hoop of one mat. Say, 'This whole is 7. Watch what happens when I split it into two parts.'
  2. Slide a small handful of the objects into one of the small hoops and the rest into the other hoop, counting each part out loud as you go.
  3. Hold up the matching picture card (for example 2 and 5 make 7) and say, 'My two parts match this card: 2 and 5 make 7.'
  4. Give each child 7 objects and their own mat. Ask them to split their 7 into two parts in their own way, counting each part as they place it.
  5. Go round the group and ask each child to say their own part-whole sentence out loud, for example 'My parts are 3 and 4. 3 and 4 make 7.'
  6. Find and hold up the picture card that matches each child's split so they can see their real objects mirrored in the picture.
  7. Ask, 'Can you split your 7 into two parts in a different way?' and let children rearrange and recount.
  8. Swap the baskets for 8 objects. Repeat the splitting, saying and matching-the-card process for 8.
  9. Introduce the feely bag: put 8 objects in, let a child pull some out without looking, then count what's left in the bag and what's in their hand, saying the part-whole sentence for 8.
  10. Finish by laying out several of the picture cards and asking children to build the matching split with their own objects on their mat.

Misconceptions

A child recounts all the objects from 1 each time instead of recognising the two counted parts combine to make the whole.Cover each part with a hand as the child counts it, say the amount, then reveal both and count on together from the first part to show the whole, for example 'Here are 3, and here are 4 more, so 3 and 4 make 7.'
A child thinks a part that is spread out over more space has more objects than a part that is grouped tightly together, even when the amounts are equal.Move the objects between a spread-out arrangement and a tightly grouped arrangement in front of the child, counting each time, so they see the amount stays the same.
A child believes there is only one correct way to split 7 or 8 and resists trying another split.Model swapping the objects between the two part hoops yourself first, then ask the child to copy you, praising each new split they find as 'another way to make the same whole.'
A child thinks swapping the two parts (for example 3 and 4 becoming 4 and 3) changes the whole.Lay out both arrangements side by side and count each whole together, showing that 3 and 4 make 7, and 4 and 3 also make 7.

Composition of 9: every way to make 9

Small group of 4 to 6 children · 15 to 20 minutes

Objective: Children explore and record every way to partition 9 into two parts, using real objects and a part-whole frame, building towards a secure understanding that 9 can always be split into two parts whose total stays 9.

eyfs.ma.number.1 Have a deep understanding of numbers to 10, including the composition of each number.

Resources

  • 9 identical small objects per child (for example conkers, shells or counters) in a pot
  • A large floor part-whole frame: one big hoop for the whole and two smaller hoops underneath for the parts
  • Numeral cards 0 to 9
  • 8 part-whole picture cards showing: 1 and 8 make 9; 2 and 7 make 9; 3 and 6 make 9; 4 and 5 make 9; 5 and 4 make 9; 6 and 3 make 9; 7 and 2 make 9; 8 and 1 make 9
  • One small empty bowl (to show a part of zero)
  • A soft cloth or cloth bag to briefly hide the whole group of 9 objects

Set-up

Lay the big hoop and the two smaller hoops on the carpet so children can sit around them. Tip 9 objects into the big hoop. Place the numeral cards 0 to 9 and the 8 part-whole picture cards face down nearby, within reach but not yet visible.

Key questions

  • How many are in this part? How many are in that part? How many altogether?
  • If I swap the two parts around, does the whole still stay the same?
  • Can one part be 0? What would that look like?
  • Have we made this way already, or is it a new way?
  • How could we check we haven't missed any way to make 9?
  • What do you notice about the pictures when we put them in order?

Vocabulary

whole, part, make, split, altogether, same, swap, zero, nine

What to do

  1. Adult says: 'We have 9 conkers in our whole hoop. Let's count them together to check.' Adult counts all 9 objects with the children, touching each one.
  2. Adult says: 'I'm going to split our 9 into two parts.' Adult moves some objects into one small hoop and the rest into the other, for example 1 object into one hoop and 8 into the other.
  3. Adult says: 'Let's count each part.' Adult counts each small hoop aloud with the children, then says the stem sentence: '1 and 8 make 9.'
  4. Adult turns over the matching part-whole picture card (1 and 8 make 9) and places it next to the hoops, saying: 'Look, this picture shows the same thing.'
  5. Adult invites a child to move the objects to make a different split, for example 2 and 7, and supports the child to say: '2 and 7 make 9.' Adult finds and places the matching picture card.
  6. Adult continues around the group, giving each child a turn to make a new split (3 and 6, 4 and 5, 5 and 4, 6 and 3, 7 and 2, 8 and 1), checking each total by recounting and matching the picture card each time.
  7. Adult says: 'What if I don't move any conkers at all?' Adult shows the empty small bowl next to the full hoop and models: '0 and 9 make 9.' Adult repeats the other way round: '9 and 0 make 9.'
  8. Adult lines up the picture cards children have matched so far and says: 'Let's look at our pictures in order. Have we found every single way to make 9, or are there any missing?' Adult supports children to check against the numeral cards 0 to 9.
  9. Adult hides the 9 objects briefly under the cloth and says: 'I've got 9 conkers under here split into two parts. Can you guess what the two parts might be?' Children suggest a split, then adult reveals to check.

Misconceptions

A child believes swapping the two parts changes the total, for example thinking 2 and 7 is different from 7 and 2.Physically swap the objects between the two small hoops while the child watches, recount both parts, and say together: 'the parts swapped places but the whole is still 9.'
A child thinks you cannot have a part of 0, saying something like 'you have to put something in both hoops.'Show the empty bowl as one part and all 9 objects as the other part, count the empty bowl together as '0', and say: '0 and 9 make 9, the empty hoop is still a part.'
A child miscounts a part after moving objects quickly, giving a total that is not 9.Pause and recount each part slowly with the child, touching each object, then recount the two parts together to check they make 9.
A child stops after finding two or three ways and says 'that's all of them.'Lay out the numeral cards 0 to 9 in order and ask the child to check which first numbers have not been tried yet, encouraging them to try the next one in the pattern.

Number bonds to 9, including zero and take away

4 to 6 children · 15 minutes

Objective: Children find and say the pairs of numbers that make 9, including 0 and 9, and use take away to explain how the two parts are connected.

eyfs.ma.number.1 Have a deep understanding of numbers to 10, including the composition of each number.
eyfs.ma.patterns.3 Explore and represent patterns within numbers up to 10, including evens and odds, double facts and how quantities can be distributed equally.

Resources

  • A real rekenrek (bead frame) with rows of 10 beads, 5 red and 5 white per row
  • 9 identical real objects per child (for example conkers, shells or pebbles) in a small pot
  • A large part-whole mat (a circle split into two smaller circles)
  • A drawstring bag or tea towel for hiding objects
  • Number cards 0 to 9
  • A small whiteboard or chalkboard for the adult to jot the bond children find

Set-up

Sit the group around a low table or on the carpet in a circle. Place the part-whole mat in the middle with 9 objects sitting in the top circle. Have the rekenrek within reach, pushed so all beads sit to one side. Spread the number cards 0 to 9 face up nearby.

Key questions

  • How many do we have altogether before we split them?
  • If one part has 3, how could we find out the other part without counting from 1 again?
  • What happens to the whole if we take some away from one part?
  • Can you make 9 a different way to your friend?
  • What do you notice about 4 and 5 compared with 5 and 4?
  • If one part is 0, what does that tell us about the other part?

Vocabulary

whole, part, altogether, make, bond, take away, left, zero, none, same, swap

What to do

  1. Gather the group and show the pot of 9 objects. Count them together into the top part of the part-whole mat: '1, 2, 3... let's check, how many have we got altogether?'
  2. Say: 'I'm going to split our 9 into two parts.' Slide some objects into one bottom circle and the rest into the other bottom circle, for example 3 and 6. Ask the children to count each part.
  3. Say the sentence together: '3 and 6 make 9.' Find the matching number cards and place them under each part.
  4. Pass the rekenrek to a child. Ask them to slide beads so that some are red on one side and white stay on the other, matching the same split (3 red, 6 white). Count each colour together.
  5. Hide the 9 objects under the drawstring bag. Take some out in full view and ask, 'If I take away 2, how many are left under the bag?' Reveal to check, then say the bond: '2 and 7 make 9.'
  6. Repeat with a new split each time, moving towards the zero fact: slide all 9 beads to one side so none are left on the other. Ask, 'What if I take nothing away? How many parts do we really have?' Introduce '0 and 9 make 9.'
  7. Let each child take a turn choosing a split on the rekenrek or part-whole mat while the rest of the group checks by counting both parts and saying the bond sentence.
  8. Finish by lining up the number cards in order and reading all the pairs the group found for 9, including 0 and 9.

Misconceptions

The child thinks 3 and 6 is a different fact to 6 and 3, rather than the same bond swapped around.Physically swap the two parts on the mat and recount each side. Say, 'Look, we still have 3 and we still have 6, we've just swapped where they sit. Both make 9.'
The child does not believe 0 can be a real part, and leaves that circle empty without saying a number.Point to the empty circle and ask, 'How many are in this part?' Count out loud to show there are none, then say together, '0 and 9 make 9', emphasising that 0 is still an answer.
After taking objects away, the child recounts the whole group again instead of checking the part that is left.Cover the part that was taken away and ask, 'We know we took 4 away, so let's just check what's hiding under the bag now,' guiding them to count only the remaining part.
The child recounts from 1 every time instead of recognising the whole stays 9 while the parts change.Hold up the pot and say, 'We already know we started with 9, that doesn't change, only how we split it does.' Keep the full group of 9 objects visible as a constant reference.

Continuous provision

Maths area

Turn the maths area into a 'Make 9' station: a floor mat with a large nine-frame (3 rows of 3 boxes) sits next to a basket of small natural loose parts and a part-whole mat (two hoops on a tray, with a large '9' numeral card above them), so children can split a group of up to 9 objects into two parts and put them back together again as they play.

Resources

  • One large nine-frame mat (3 rows of 3 boxes), floor-sized, for children to fill with objects
  • Baskets of small loose parts to count out, such as shells, conkers, pebbles or buttons, with at least 9 in each basket
  • A part-whole mat: a tray with two hoops (or two small plates) underneath a card showing the numeral 9
  • Numeral cards 0 to 9, laminated, for labelling each part
  • Two small pots or jars for children to pour and sort objects into
  • A 9-space egg box or seed tray with compartments, for hiding some and showing others
  • A small cloth or scarf for covering some of the objects in the nine-frame
  • A tuff tray or mat version of a 'bus' or 'train' with 9 numbered seats/windows, for small-world figures

When you join the play

  • How many are in your basket altogether? Can you check by counting?
  • You've put some shells in each hoop. How many are in this part, and how many in that part? Do they still make 9 together?
  • I can see 6 in the nine-frame and some are hidden under the cloth. How many are hiding?
  • What if one hoop has 0 in it? Where would the rest of the 9 be?
  • Can you find a different way to split your 9 into two parts?
  • You had 9, and then 3 went on the bus. How many are left waiting?
  • Show me with your fingers: some on one hand, some on the other, making 9 altogether.

Look for

  • Children filling the nine-frame and recognising when it shows 9 without needing to count every box
  • Children splitting a group of up to 9 objects into two parts and checking the parts still make the same whole
  • Children noticing that 0 and 9 still make a pair that totals 9
  • Children using fingers, the egg box compartments or the two hoops to hold each part while they count
  • Children spotting that swapping the two parts (for example 2 and 7, then 7 and 2) still makes 9
  • Children linking a 'take away' action, such as figures leaving the bus, to how many are left of the 9
  • Children learning English using the loose parts and pointing/matching numeral cards to show their thinking without needing many words

Construction

Turn the construction area into a builders' yard with a wall-building challenge: the yard always needs a wall, bridge or tower made of exactly 9 bricks, built using two trucks, two trays or two hands of a builder puppet, so children keep discovering different ways to split 9 as they build and knock down and rebuild.

Resources

  • Wooden or foam building blocks, at least 9 of one colour and 9 of a second colour
  • Two small builders' trucks, trays or buckets for carrying bricks to the wall
  • Large numeral cards 0 to 9 pegged to the yard fence
  • A site sign reading '9 bricks needed for today's wall'
  • High-vis vests and hard hats for role play
  • A long plank to use as a bridge base for laying bricks along
  • A builder puppet or small world figure who 'orders' how many bricks for each side

When you join the play

  • The builder needs 9 bricks for the wall. You've put 4 on the truck. How many more does the other truck need to bring?
  • Can you build the same wall of 9 bricks a different way, so the two trucks carry a different split?
  • What if one truck carries 0 bricks today? How many would the other truck need to carry to still make 9?
  • I can see 6 bricks on the bridge and 3 bricks waiting. What do 6 and 3 make together?
  • The wall had 9 bricks but 2 fell down. How many are still standing?
  • How could you check that both trucks together really do make 9?

Look for

  • Children splitting 9 bricks between two trucks or trays and checking the total comes to 9
  • Children trying more than one way to split 9, for example 5 and 4, then 7 and 2
  • Children using the idea of 0, for example one truck empty and the other carrying all 9
  • Children subitising small groups of bricks rather than counting every one from 1
  • Children predicting how many bricks are left after some are taken away from a group of 9
  • Children explaining their split of 9 to a friend or the adult using number names

Small world

Turn the small world area into a 'Barn and Field' farm with a fixed herd of 9 small world animals, so children naturally split, re-group and recombine 9 as they play out stories of animals moving between the barn and the field.

Resources

  • 9 small world farm animals, all the same type (for example 9 sheep), kept together in one labelled basket so the total of 9 stays fixed
  • A large felt or wooden small world mat split into two clear zones: 'barn' and 'field'
  • A small barn model (box or wooden structure) and fencing to mark the field edge
  • A 9-space ten frame printed onto a tray or mat, placed beside the small world for children to move animals onto if they choose
  • Number cards 0 to 9 for children to post into the barn and the field to label how many are in each
  • Small baskets or crates (two per set) for scooping up and carrying animals between zones
  • A simple laminated story card showing a farmer figure, for adults or children to use when inventing 'moving' stories

When you join the play

  • You've got 9 sheep altogether today. How many are in the barn and how many are out in the field?
  • If 4 sheep are in the field, how many must be in the barn, so we still have 9?
  • Can you move one sheep from the field into the barn? What happens to the two amounts now?
  • Is there another way to split the 9 sheep between the barn and the field?
  • What if all 9 sheep went into the field and 0 stayed in the barn? Is that still 9 altogether?
  • Can you find the number cards that show how many are in each part?

Look for

  • Children physically moving animals between the two zones and recounting each part
  • Children finding more than one way to split 9 (for example 2 and 7, then trying 5 and 4)
  • Children checking that both parts still add back up to 9 altogether
  • Children using the ten frame alongside the small world to check their counting matches
  • Children noticing that as one group gets bigger, the other gets smaller
  • Children selecting or placing the matching number cards for each part without an adult prompting
  • Children using zero correctly, recognising that 0 and 9 still make 9

Outdoors

Set up a 'Splitting Station' in the outdoor area: a builder's tray or digging pit holding 9 loose-part treasures (conkers, pebbles or shells) next to two hoops laid on the ground as 'homes'. Children scoop, carry and tip the 9 treasures, deciding how many go in each hoop, then check their total against a large chalk ten-frame drawn alongside. Nearby, a skittles alley with 9 skittles and a soft ball lets children knock some down and work out how many are left standing, linking to take away and bonds to 9.

Resources

  • A builder's tray or shallow digging pit with 9 matching loose-part treasures (conkers, pebbles, shells or pinecones)
  • Two large hoops or plant pots to use as 'homes' for splitting the treasures
  • A ten-frame drawn in chalk directly on the tarmac or playground floor, large enough for children to place treasures or stand in the squares
  • A set of 9 skittles and one or two soft balls for an outdoor skittle alley
  • Numeral cards 0 to 9 pegged to a washing line or taped along a fence
  • A chalk number line 0 to 9 on the ground
  • Buckets, scoops and trugs for carrying and tipping the treasures

When you join the play

  • You've got 9 treasures in your bucket. If you tip some into the red hoop, how many do you think will be left for the blue hoop?
  • I can see 3 in this hoop. How many more do we need to make 9 altogether?
  • You knocked down 4 skittles. How many are still standing out of our 9?
  • Can you find two different numeral cards that make 9 when you put them together?
  • What happens to the two hoops if we start again with 0 in one of them?
  • Is there another way to split your 9 treasures between the two hoops?
  • Can you show me 9 on the chalk ten-frame, then show me how many more you'd need if I take some away?

Look for

  • Children splitting the 9 treasures between the two hoops in different ways without being told to
  • Children checking their two groups still make 9 altogether, by counting all or counting on
  • Children matching numeral cards to the amounts in each hoop, including a card showing 0
  • Children predicting how many skittles are left standing before counting to check
  • Children using the chalk ten-frame to organise their count rather than counting at random
  • Children repeating the splitting game with the same 9 treasures and noticing the pairs of numbers that keep appearing
  • Children explaining their thinking aloud, using words like 'altogether', 'left' and 'more'

Malleable (playdough)

Turn the playdough table into a 'Snail Shop' where children roll playdough snails and pair them onto number mats showing 9 shell spaces, so they physically split 9 snails between two leaves or two shells and see every way to make 9.

Resources

  • Playdough in at least 2 colours, enough for each child to make up to 9 small balls or snails
  • Flat mats or paper plates each printed with a single large shell outline split into two sides by a line, for 9 to be shared between the two sides
  • Small leaf-shaped mats, each with space for up to 9 playdough snails
  • Shallow trays with 9 dots or 9 shallow thumbprint hollows pressed in for children to fill
  • Rolling pins, lolly sticks and blunt tools for marking snail shell spirals
  • Small bun cases or pots in two colours, 2 per child, for sorting snails into
  • Laminated numeral cards 0 to 9 for labelling how many on each side
  • Picture cards showing 0 to 9 playdough dots as a matching reference
  • A simple bilingual or symbol label mat saying 'this side' and 'that side' in English and other languages spoken in the setting, for children learning English

When you join the play

  • You've made 9 snails altogether. If 4 go on this leaf, how many are left for the other leaf?
  • Can you make 9 snails a different way, so it isn't 4 and 5 this time?
  • What if all 9 snails went onto one leaf, and none went on the other? Is that still 9 altogether?
  • I can see 3 snails here. How many more playdough balls do you need to roll to make 9 altogether?
  • Let's check together: if we put the two leaves back together, do we still have 9 snails?
  • Can you show me 9 made with just two snails, by making one snail really big?

Look for

  • Children splitting 9 playdough pieces into two groups without being asked, such as 6 and 3 or 2 and 7
  • Children recounting all the pieces together to check the total is still 9 after splitting them
  • Children swapping pieces between the two sides and recognising the total stays the same
  • Children using the numeral cards to label each side correctly, for example 1 and 8
  • Children showing 0 and 9 by putting every snail on one side and none on the other
  • Children spotting that 3 and 6 make 9 in the same way that 6 and 3 make 9, just swapped around

Role play shop

Turn the role play shop into a 'Nine Pence Pocket Money Shop' where every item costs 1p, so children build amounts up to 9p and find different ways to make 9p using two coins or two piles of coins.

Resources

  • A till or tray with nine compartments, plus a basket of play 1p coins (at least 18, so two piles can be made)
  • Small shop items or empty packets priced individually from 0p to 9p using numeral price tags (use real numerals, not symbols like p alone without a number)
  • Two small purses or pots labelled 'my coins' and 'your coins' for splitting 9 coins between a shopkeeper and a customer
  • A nine-frame mat (a strip with nine spaces) by the till for lining up coins as they are counted
  • A simple picture price list showing items with dots or coins next to them matching numbers 0 to 9
  • A bag or two trays for sorting coins into two groups when paying for a 9p item

When you join the play

  • You've got 9p to spend today. If you put 3p in your purse, how many pennies are left for your pocket?
  • Can you pay for this 9p toy using two piles of coins? Show me one way, then show me a different way.
  • I'll be the customer with 4 coins. How many coins do you need as the shopkeeper so we have 9 altogether?
  • What if you had 0p left in your purse — how many would be in the till?
  • You've given me 9p but I want to give you 2p change. How many pennies should I keep?
  • Let's line the coins up on the strip. How many more do we need to reach 9?

Look for

  • Children splitting 9 coins into two groups without recounting from one every time
  • Children recalling a pair, such as 4 and 5, from memory rather than counting all the coins again
  • Children noticing that if one pile grows, the other pile shrinks by the same amount
  • Children using the nine-frame or coin strip to check how many more are needed to make 9
  • Children acting out zero, such as saying the till is empty and all 9 coins are in the purse
  • Children using take away language, such as saying 9 take away 3 leaves 6, during buying and selling

Read the note

Dear families,

This half term in Reception your child is exploring how numbers up to 9 can be split into two smaller parts and put back together again. They have been building numbers on ten frames, working out how many more are needed to make 9, and exploring the different ways to break apart 7 and 8.

By the end of the unit, children will know all the ways to make 9 from two parts, such as 4 and 5, or 3 and 6. They are also learning about zero as a part (for example, 9 and 0 still make 9) and starting to connect this to simple take-away, such as knowing that if 9 take away 2 leaves 7, then 2 and 7 must make 9.
