*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 number and counting on or back.*

In Year 1 children are taught how to count forwards and backwards and to understand numbers. This is about understanding where numbers belong and putting them in the right order. Counting forwards in ones is the same as adding one on each time, and counting backwards in ones is the same as subtracting one each time.
