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 understanding subtraction.
Subtraction is a key number operation, usually taught closely with addition. Understanding it begins with removing one group of objects from a larger group and then counting the remaining objects to find how many are left. This may lead to using numbers to represent the objects, number lines to support counting back and also to beginning to understand all the language associated with subtraction.
