It's beneficial for learners to be able to recall their addition and subtraction number bonds to ten fluently - this frees up working memory for problem solving and higher order analytic thinking. It also introduces the strategy of breaking numbers into parts in order to simplify operations such as addition, subtraction, multiplication and division.

The Number Bond Challenge is essentially a number bond question generator for class and individual practice.

There are 5 steps:

  1. Choose your Bond family - children may need to be prompted to come back here to choose another bond family after completing the first one!
  2. 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.
  3. Whole and Parts - a familiar model from "Singapore Maths"
  4. Practise the Number Bonds -  generates the relevant bonds for each "break". Simply click on the place holders to answer each question. 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 practised all the number bonds to 10  - the bond family chooser (Step 1) will display a "completed tick" for each bond family:
