Number bonds tracker
Track bonds to 5, 10, 20, 100 and decimal bonds to 1.
Quick answer
A number bonds tracker is a tool that helps you keep track of which number bonds (pairs of numbers that add up to a target number) you know and which ones you still need to learn. It's like a progress chart that helps you see your maths journey and celebrate your successes.Learning outcome
By the end of this page, you will be able to use a number bonds tracker to identify which number bonds you know and which ones you still need to learn, so you can focus your practice on the right areas.Why this matters
Number bonds are important because they help you understand how numbers work together. When you know your number bonds well, you can add and subtract numbers quickly and easily. A tracker helps you see your progress, stay motivated, and focus your learning. It's like having a personal coach who tells you exactly what you need to practice next.How it works
A number bonds tracker works like a checklist. You start with a list of number bonds (like all the pairs that add up to 5, 10, 20, or 100). Then you go through each pair and mark it as "known" or "learning". You can use a chart or a simple list to keep track. As you learn more bonds, you move them from "learning" to "known". This way, you always know exactly what you need to practice.Examples you can see
Let's look at how to make a number bonds tracker for bonds to 10:| Bond to 10 | Known? |
|---|---|
| 0 + 10 = 10 | |
| 1 + 9 = 10 | |
| 2 + 8 = 10 | |
| 3 + 7 = 10 | |
| 4 + 6 = 10 | |
| 5 + 5 = 10 |
Try it as a mini adventure
Imagine you are a detective who needs to solve a mystery about numbers. You are looking for pairs of numbers that add up to 10. You have a notebook where you can write down all the pairs you find. As you find each pair, you mark it with a star. Your mission is to find all the number bonds to 10 and collect all the stars. You start with 0 + 10 = 10, then 1 + 9 = 10, then 2 + 8 = 10, and so on. When you have found all the pairs, you can use your notebook to show your detective work to your friends.Common mistakes
Mistake: Thinking that 6 + 4 = 11 instead of 10. Why it happens: This is a common mistake when children are counting or adding quickly. They might miscount or forget to double-check their work. How to fix it: Use objects like counters or blocks to help you see that 6 + 4 is exactly 10. Count them together to make sure. Mistake: Forgetting to check if a pair adds up to the target number. Why it happens: When children are working quickly, they might not double-check their work. How to fix it: Always count or use objects to check that your two numbers add up to the target number. For example, if you think 7 + 3 = 10, count 7 + 3 to make sure. Mistake: Not using the tracker to guide practice. Why it happens: Some children might not see the value in tracking their progress. How to fix it: Explain to yourself or your parent that the tracker helps you know what to practice next, so you don't waste time on things you already know.Parent and carer guide
Parents and carers can help by:- Creating a simple number bonds tracker together with their child
- Using everyday situations to practice bonds, such as counting apples or toys
- Encouraging children to mark off bonds they know and celebrate their progress
- Using the tracker to guide practice time, focusing on bonds that are still being learned
- Not pressuring the child to memorize everything quickly, but encouraging regular practice
