Number bonds resources for KS1 give children aged 5 to 7 a way to see how numbers fit together. They use practical activities, games and worksheets to support pupils in Years 1 and 2.
These materials help children develop quick recall of addition facts. That foundation supports all their future maths learning. The best KS1 number bonds resources mix visual models, hands-on practice and repeated activities so children recognise how numbers combine to make totals like 10, 20 and eventually 100.
Michelle Connolly, founder of LearningMole and a former primary teacher with over 15 years of classroom experience, says: “Number bonds aren’t just about memorising facts. They’re about helping children see the relationships between numbers so they can work flexibly with addition and subtraction.”
LearningMole, a UK educational platform, provides curriculum-aligned resources including free videos and activities made for primary pupils.
You’ll notice that number bonds resources range from simple matching activities for early learners to more challenging problem-solving tasks for confident Year 2 pupils.
A good mix of printable worksheets, interactive games and practical equipment helps every child build the mental fluency needed for the National Curriculum.
Key Takeaways
Number bonds build the basics of addition and subtraction in early primary years. They show children how numbers can split and combine, making mental calculations quicker and more accurate.
Number bonds are pairs of numbers that add together to make a bigger number. For example, 3 and 7 make 10 because 3 + 7 = 10.
In KS1, children start with number bonds to 10 and then move to bonds within 20. These include all the ways to make a target number, like 0 + 10, 1 + 9, 2 + 8, and so on.
Common number bond sets for KS1:
Once children know that 4 + 6 = 10, they also see that 10 – 6 = 4. This shows how addition and subtraction connect.
Number bonds help children create a mental image of how numbers relate. This lets them move past counting on their fingers and start to recall number facts automatically.
KS1 maths depends on this knowledge. Without strong number bonds, children struggle with column addition, subtraction with regrouping, and word problems that need fast mental maths.
The National Curriculum asks Year 1 pupils to recall all number bonds to and within 10. By Year 2, they should know bonds to 20 and begin to understand place value through bonds to 100.
Children who master number bonds early often show more confidence and flexibility in maths. They break down bigger numbers into smaller chunks, which makes tricky problems feel less scary.
Number bonds let children work out sums in their heads without writing anything down. If a child remembers that 7 + 3 = 10, they can quickly see that 17 + 3 = 20 or 27 + 3 = 30.
This instant recall matters for harder arithmetic. To add 8 + 5, a child might split 5 into 2 + 3, add the 2 to 8 to make 10, then add the 3 to get 13.
Mental strategies based on number bonds:
Children who recall number bonds without thinking can focus more on solving the actual problem. They waste less time on simple sums and more on understanding the question.
Young learners in Key Stage 1 need to know number pairs that add up to 5, 10 and 20. These facts are the building blocks for all mental maths and help children see how numbers fit.
Number bonds to 5 are the first step in showing pupils how numbers combine. These pairs include 0+5, 1+4, 2+3, 3+2, 4+1 and 5+0. Children usually learn these in Reception and Year 1.
Try using physical objects like counters or cubes. Split five items into groups and let children see the total always stays the same. This hands-on approach helps them picture how two parts make a whole.
Teachers often use visual models like number bond activities to help children remember these facts. Pupils should practise until they can recall these pairs without counting. Quick recall means they can tackle harder problems later on.
Number bonds to 10 matter for Year 1 pupils and show up throughout the National Curriculum. These include pairs like 1+9, 2+8, 3+7, 4+6 and 5+5. Children need to know these facts for speedy mental maths.
Teaching number bonds in KS1 means giving lots of practice with practical tasks and visual models. You might use ten frames, bead strings or part-whole models to show how numbers split and combine.
Games and activities work well for learning bonds to 10. Pupils can use number bonds worksheets that give practice with missing number sentences. Short sessions of 5 to 10 minutes, done regularly, beat longer, less frequent practice.
Number bonds to 20 stretch pupils’ understanding and usually appear in Year 2 of KS1. These include combinations like 11+9, 12+8, 13+7 and so on. Children who know their bonds to 10 often find these easier, as they spot patterns.
You can teach these by building on what children know about bonds to 10. If they know 6+4=10, then 16+4=20 makes sense. This link helps them get place value and the structure of numbers.
Interactive games keep practice fun. Some children like real-world examples like fractions and sharing equally, which show how numbers combine in real situations. Knowing these bonds helps children with mental addition and subtraction up to 100.
Learning number bonds to 100 needs a solid grasp of smaller bonds and builds on children’s understanding of place value. Year 2 pupils usually start with multiples of 10 before moving to more complex combinations that total 100.
Number bonds to 100 play a big part in the Year 2 maths curriculum and help children work out sums in their heads. Start with bonds using multiples of 10, such as 30 + 70 = 100 or 60 + 40 = 100.
These are easier for children to understand as they link directly to place value. Once your pupils are confident with tens, bring in single-digit additions like 43 + 57 = 100 or 28 + 72 = 100.
Visual aids work well at this stage. LearningMole has free videos showing these ideas with examples and animations. You can also use hundred squares, number lines or place value charts to help children see the link between the two numbers.
Your pupils already know their number bonds to 10 and 20. That knowledge sets them up for bonds to 100. The main thing is spotting patterns between smaller and larger number bonds.
If a child knows 3 + 7 = 10, they can see that 30 + 70 = 100. This kind of pattern helps build confidence with bigger numbers. You can make worksheets that show these links side by side.
Show bonds to 10 next to their matching bonds to 100. Ask pupils to spot what’s the same and explain the link. This way, you reinforce place value and build on what they already know.
Children need regular practice to recall number bonds without counting. Interactive games and activities make this practice more interesting than worksheets alone.
Aim for short, daily practice sessions. Five minutes a day works better than one long session a week. Use different formats like matching activities, missing number problems and quick-fire challenges.
Good practice methods:
Some children will get bonds to 100 quickly. Others might need more support and scaffolding.
Physical tools and visual models help children see how numbers work together to form bonds. These resources turn abstract ideas into something children can touch and move, which really helps KS1 learners who need to handle objects while learning.
Numicon pieces use coloured shapes with holes to show number values through their patterns. Each shape stands for a different number, so children can actually see and feel what seven looks like compared to three.
If you put together a three piece and a seven piece, they fit the ten piece exactly. This makes number pairs obvious and easy to touch.
Children stack, compare and combine these shapes to explore different number bonds. The patterns help them spot relationships quickly.
A Year 1 class might use them every day during carpet time. Children place shapes on a baseboard to find all the ways to make ten.
Other manipulatives like counters, cubes and beads work in similar ways. Give children ten cubes and ask them to split them into two groups, then record the bond they’ve made.
This hands-on approach helps children who find worksheets difficult.
Part-whole models use circles connected by lines to show how two smaller numbers come together to make a bigger number. The whole sits at the top, with the two parts below.
This layout matches how children naturally think about splitting and combining.
Draw a large circle for the total number, then two smaller circles underneath for the parts. If you’re teaching bonds to ten, write ten in the top circle, then six in one bottom circle.
Children work out that four must go in the empty circle.
These models appear throughout KS1 number bonds teaching resources. They link directly to the bar models used later.
They help children realise that addition and subtraction are connected. You can use them on whiteboards, in workbooks or make big floor versions with hoops and number cards.
Ten frames are grids with two rows of five squares. They help children visualise numbers up to ten.
When children place counters on the frame, they instantly see how many squares are filled and how many are empty. This makes spotting number bonds to ten much easier than counting loose objects.
A common approach is to fill the top row first, moving left to right. If a child places seven counters, they fill the top row and add two to the bottom row.
The three empty squares show that seven and three make ten.
You can use physical ten frames with actual counters or print versions for children to colour in. Activities that develop number sense often include ten frame games where children roll dice and fill frames, racing to complete them.
LearningMole offers video demonstrations of ten frame strategies, showing different ways to arrange counters and explore bonds. The structure of the frame helps children avoid miscounting and quickly spot number patterns.
Teachers can choose from worksheets for solo practice, collaborative tasks for pairs or groups, and resources with built-in answer keys. These materials support KS1 number bonds learning across different classroom settings.
Printable number bonds worksheets give children focused practice with the mental pictures they need to understand how numbers work together. You’ll find worksheets targeting skills like number bonds to 10 and number bonds to 20, which are key instant recall facts for Year 1 and Year 2 pupils.
The best worksheets include visual elements like empty circles or boxes for children to fill in and complete number sentences. Many free number bonds worksheets use characters, stories, or colour coding to make practice more engaging than traditional drills.
Teachers often notice that worksheets with varied question types work best. These might include missing number problems, fact families, and simple addition pairs.
You can download resources in colour or black and white, which helps with printing costs.
Number bonds games and activities work well when children learn together through discussion and problem solving. Paired work lets one child solve while their partner checks, then they swap for the next question.
Group activities often use larger visual aids like number bond mats or anchor charts that several children can gather around. You might print one set of teaching resources in colour for the whole table to share.
LearningMole offers free videos showing number bonds concepts you can play before group activities, helping children understand what they’ll practise together.
Answer pages help children become independent by checking their own work without waiting for teacher feedback. Most printable worksheet packs include answer sheets alongside the main activities, which saves you time making marking guides.
Self-checking teaches children to spot their own mistakes and see where their thinking went wrong. You can laminate answer sheets and put them at a checking station for pupils to use once they’ve finished their worksheet.
This approach works well for number bonds practice because the answers are straightforward facts. Children can circle incorrect answers, try again, and build confidence as they master each set of number bonds.
Online games and digital apps give children immediate feedback while practising KS1 number bonds. These tools work well in classrooms and at home to build fluency with number pairs.
Hit the Button gives quick-fire questions on number bonds with timed challenges that build mental maths skills for 6 to 11 year olds. The game includes an untimed practice mode so children can build confidence before trying speed challenges.
LearningMole provides free curriculum-aligned videos explaining number bonds to 10 and 20 with visual demonstrations. The platform’s interactive resources suit both classroom teaching and home learning for children aged 4 to 11.
You can also find engaging number bond games that use colourful characters and stories to keep young learners interested. Many games adjust difficulty automatically based on your child’s progress.
The interactive number bond tool lets children explore addition and algebraic reasoning through hands-on manipulation. This works brilliantly for whole-class teaching on an interactive whiteboard or for individual practice on tablets.
Digital games give instant feedback so children can spot mistakes straight away and try again. This immediate response builds problem-solving skills without waiting for teacher marking.
You can use online games during guided maths sessions to support differentiation. Children working below age-related expectations benefit from visual aids and repeated practice, while those working at greater depth can try timed challenges.
Tablets and computers let children work independently during maths stations or early morning activities. The games track progress automatically, giving you insights into which number bonds need more practice.
Many teachers set these resources for homework because parents find them easier to support than traditional worksheets. Children often choose to play number bond games in their free time when the activities feel like play.
Set up weekly number bond competitions using timed games. Children try to beat their personal best scores.
Display a class leaderboard that celebrates improvement, not just top scores.
Create mixed-ability pairs where children take turns playing interactive number bond games on shared devices. This encourages peer teaching and discussion about strategies.
Use whole-class games on your interactive whiteboard for quick 10-minute starter activities. Children can come up to tap answers while classmates record number sentences in their maths books.
Design reward systems where children earn game time after completing written tasks. This motivates reluctant learners and shows that digital practice supports traditional methods.
Number bonds stick better when children learn through play, daily routines and creative expression. These hands-on approaches help young learners see how number pairs work in real life.
Children learn number bonds more quickly when they connect maths to everyday tasks. During snack time, you can ask your class to share out 10 grapes between two friends and record the pairs they find.
Measuring ingredients precisely gives another natural way to explore number bonds. When making a recipe with 10 spoonfuls of flour, children can try combinations like 7 plus 3 or 6 plus 4.
Setting the table works too. If you need 10 pieces of cutlery, ask children to fetch some knives and some forks that add up to 10. They might bring 4 knives and 6 forks, then next time try 8 knives and 2 forks.
Other daily number bond opportunities:
Stories make number concepts concrete and memorable. Tell simple tales where characters solve problems using number bonds. For example, “Ten birds sat on a fence. Some flew to the tree. How many stayed on the fence?”
Use puppets or toys to act out these stories. Children get invested in helping characters solve their maths problems.
Let your class invent their own number bond stories. They might write about 10 sweets shared between friends or 10 flowers planted in two gardens. This creative approach helps them see that number pairs can represent many real situations.
Story themes that work well:
Drawing and making things helps children visualise number bonds in colourful, hands-on ways. You can give templates of trees with 10 branches. Children colour some leaves red and others yellow, then write the matching number bond.
Children often enjoy making number bond flowers. Draw a flower with a number in the centre and write different number pairs on each petal that add up to that total.
Playdough offers engaging activities for teaching number bonds through splitting and counting. Children roll out 10 balls, divide them into two colours and record what they find.
Simple craft activities:
Every child learns at their own pace. KS1 maths needs flexible approaches that meet pupils where they are.
Adapting number bonds resources for special educational needs, using play to build confidence, and working with families creates an inclusive environment where all learners can succeed.
Children with special educational needs often learn best with concrete, visual approaches to number bonds. Numicon resources work particularly well because the physical shapes let pupils see and feel number relationships.
The tactile nature of these materials helps children who find abstract concepts difficult. Double-sided counters offer another hands-on option for learners who need visual support.
You can use ten-frames with coloured counters to show number pairs. Pupils can move and arrange them until they spot the pattern.
This method suits children with dyscalculia or working memory difficulties. Part-whole models break number bonds into smaller steps.
You can change the target number to suit different needs. Start with bonds to 5 for those who need extra support.
When pupils are ready, move on to 10. Keep worksheets simple and uncluttered, with lots of white space.
This helps children with processing difficulties avoid visual overload.
Games take away the pressure of formal learning and reinforce number bond skills. Interactive games on tablets or laptops grab the attention of reluctant learners who might avoid worksheets.
These activities feel playful, which eases maths anxiety. Board games give children a chance to interact socially while learning maths.
You can use them in small groups, letting children support each other. A little competition can motivate pupils, as long as it doesn’t add stress.
Simple games with clear rules work best. Children can focus on the maths instead of tricky instructions.
Pick resources that fit children’s interests. Space-themed activities are great for those fascinated by planets and rockets.
Ladybird spot games connect with children who love nature. Linking number bonds to topics children already enjoy makes them more likely to join in.
Parents really do help reinforce number bonds at home. Share simple activities families can try together, like counting stairs or finding number pairs while shopping.
These everyday moments show children that maths is part of daily life, not just schoolwork. Give parents clear, simple guidance so they feel confident supporting their child.
Many parents feel nervous about teaching maths, especially if they struggled themselves. Show them easy games and activities that don’t need special materials.
LearningMole has free video resources that explain maths in an accessible way. These videos help parents understand what their children are learning.
Send home visual aids like number bond flashcards or basic worksheets. Keep parents updated with quick notes about what you’re covering in class.
When parents know the current topic, they can reinforce it naturally during daily routines.
Regular assessment tells you which number bonds your pupils have mastered and where they need more practice. Teachers use tracking tools for number bonds fluency and classroom observations to build a clear picture of each child’s progress.
Quick daily checks give you instant feedback about your pupils’ understanding. You can use exit tickets at the end of a lesson, asking children to answer three number bond questions on a slip of paper.
Flash card activities fit nicely into morning routines. You can spot which pupils answer quickly and confidently.
Partner work lets you hear how children explain their thinking. Listen in during paired activities to catch misconceptions early.
Mini whiteboards work well for whole-class assessment. You can scan the room and see who needs help in seconds.
Games also give you assessment opportunities that feel natural to children. When pupils play matching activities or race to complete bonds to 10, you can watch their strategies and speed.
Keep a clipboard handy to jot down notes about pupils who struggle or those ready for more challenge.
A systematic approach to recording progress helps you make sure no child slips through the cracks. Use spreadsheets that track fluency across your class with colour-changing cells so you can see at a glance which bonds each pupil knows.
These trackers often show percentages, helping you spot which bonds need more teaching time. LearningMole offers free videos demonstrating number bonds, which you can use during intervention sessions while tracking individual responses.
Paper-based trackers suit small group interventions. Tick off each bond as children show instant recall.
Test bonds to 10 first, then move to bonds to 20 following the KS1 maths progression. Record the date when a child achieves quick recall of each set.
This timeline lets you measure growth over the year and plan next steps for different groups.
Recognition really motivates children to keep practising until number bonds become automatic. Set up a visual display where pupils add a sticker or move their name along a track each time they master a new set.
Some teachers use certificate systems: bronze for bonds to 5, silver for bonds to 10, and gold for bonds to 20. Share progress with parents using simple notes home explaining which bonds their child has mastered.
This helps families know what to practise and celebrates learning in a specific way. Peer recognition is powerful in KS1 classrooms.
When a child masters all their bonds to 10, let them choose a friend to share their achievement with during circle time. You might pair children who have mastered certain bonds with those still learning, giving confident pupils a chance to teach and strengthen their own understanding.
The right materials and teaching approach can make a big difference in how well children grasp number relationships. You need to match resources to your pupils’ development stages and weave them into your everyday maths lessons.
Year 1 pupils usually start with concrete resources like counters, ten frames, and number lines before moving to pictorial representations. Choose resources that match where your class is on this concrete-pictorial-abstract journey.
Think about these factors when choosing materials:
Look for teaching resources for number bonds that let children physically partition numbers. Downloadable materials you can laminate often give better value than single-use worksheets.
Year 2 pupils benefit from resources that connect number bonds to addition and subtraction. This helps them see how the concepts fit together.
Short, frequent practice sessions work better than long, occasional activities for building fluency with KS1 number bonds. You can use five-minute starter activities with number bond cards or quick games during transitions.
Try these ideas in your daily routine:
Change up your resources weekly to keep things fresh. Combine visual aids with verbal explanations, and always show how to use new materials before letting children try on their own.
Maybe introduce a new game on Monday, practise together on Tuesday, then let children use it independently later in the week. This step-by-step approach builds confidence with each resource.
Teachers and parents often want practical advice about starting number bonds with young learners, finding quality materials, and making learning memorable with fun activities.
Start with physical objects children can touch and move. Use counters, building blocks, or even toys to show how numbers split and combine.
Classroom games like “Last man standing” and “Round the world” work well for practising number bonds to 10. These games let you adjust questions so everyone can join in.
The interactive whiteboard game “SPLAT” gets children moving while learning. Place answers around the screen and pupils race to splat the correct answer when you call out a number bond question.
Number bond worksheets for bonds to 10, 20, 50, and 100 include graded activities with different question types. You’ll find number bond searches and matching activities that get harder as you go.
Twinkl offers a wide collection of number bonds resources including worksheets for number bonds from 5 through to 100. LearningMole provides curriculum-aligned video resources and printables for Key Stage 1 learners.
Number bonds to 10 and 20 resources are available as worksheets, booklets, and activities to build recall and fluency.
Children usually start learning number bonds in Reception and Year 1, between ages 4 and 6. Early years pupils begin with smaller numbers like bonds to 5, then move to bonds to 10.
The progression continues through Year 2 as children learn number bonds to 20 and beyond. Every child develops at their own pace, so some may pick up these ideas quickly while others need more time.
Number bonds worksheets covering bonds to 100 offer ready-made printable activities for KS1 maths lessons. These resources help you plan engaging lessons without hours of prep.
A counting stick with post-it notes makes a great hands-on teaching tool. Write each multiple on a post-it, stick them along a metre stick divided into 10cm sections, then gradually remove the notes as children chant the number facts.
Target board starters are excellent for daily warm-ups. Display a 4×5 grid with different numbers and ask pupils to answer questions like “Which numbers are multiples of 10?” or “Find the number which is double 18”.
Transition times between activities are perfect for practising number bonds without taking up lesson time. Get your class to recite number bonds when moving from desks to the carpet or lining up.
“Ask me!” badges encourage children to share their achievements around school. When pupils wear badges saying “I’ve learnt my number bonds to 10”, other staff can praise them and check their understanding.
Letting pupils become teachers really helps cement their learning. Put children in groups to make rhymes or posters about specific number facts, then have them teach each other through mini lessons or presentations.
Board games and counting activities at home reinforce counting skills for early Key Stage 1. Parents can make a game of counting up and down in steps of 2, 5, and 10 while walking or climbing stairs.
BBC Bitesize offers free number bonds learning resources made for early years maths. Adults, children, parents and teachers can use these together.
