The Number Bond Challenge - Make Addition and Subtraction Number Bonds to 10 Easy!
Parents know that confidence in math opens a world of opportunities to children. And one of the best ways to gain confidence in any mathematical skill is through practice - that's why we've developed the Number Bond Challenge!
The Number Bond Challenge is a five step practice activity for children in Kindergarten and 1st Grade. It will help your child understand and become fluent in the important skill "addition and subtraction number bonds (or number facts) to 10".
We've made it fun to use and there's a cool certificate for each child who completes the challenge and the quiz.

This video explains what number bonds are using the "whole and parts" idea:
Most skills develop through practice - and math is no exception to this. The number bond challenge makes this practice effective and fun.
It's great if learners can recall their addition and subtraction number bonds to ten fluently - this frees up working memory for problem solving and higher order thinking. It also introduces the strategy of breaking numbers into parts to simplify operations such as addition, subtraction, multiplication, and division.
The Number Bond Challenge generates number bond questions so that children can do some essential practice.
There are five steps:
- Choose your bond family - you might need to remind your child to come back here to choose another bond family after completing the first one!
- Break into parts - this allows children to "chop" the number into the available parts. You'll see that we haven't included zero as a part. Also, note the sentence below indicating how many breaks you've made.
- Whole and parts - a familiar model from "Singapore Math" shows the two parts that make up the whole number
- Practice the number bonds - generates the relevant bonds for each "break". Simply click on the place holders to answer each question. When the bonds are complete, learners will see a link to "Make a New Break" which prompts them to break the number into different parts.
When learner the has practiced all the number bonds to 10 - the bond family chooser in step 1 will display a "completed tick" for each bond family:
Our Kickstart Math Quiz System requires registration with a parent's email address. This is so that we can email you your child's report and certificate privately.
1) Choose your Bond Family
Remember to practice all 6 bond families!
and when you're ready:
5) Take the number bonds to 10 quiz
Great! You're now ready to take the number bonds to 10 Quiz!
To begin the quiz, you'll need your parent to register - this is because we email your certificate to them and let them know how well you have done.
Well done for taking the Number Bond Challenge! If you didn't do as well as you'd like, don't worry. Just come back, do a little more practice and take the quiz again.
