Year 1 Numbers - Number Bonds to 20
This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 5 and 6 in year 1. Specifically this quiz is aimed at the section dealing with representing and using number bonds and related subtraction facts within 20.
As part of learning about addition and subtraction, children in Year 1 will learn about pairs of numbers which add together to make twenty. These are known as number bonds to twenty and are useful when calculating quickly. Once the addition facts, or number bonds, are learnt by heart, children may then learn the associated subtraction facts. For example, if 17 + 3 = 20, then 20 - 3 = 17 or 20 - 17 = 3.
