This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 6 and 7 in year 2. Specifically this quiz is aimed at the section dealing with adding or subtracting two, two-digit numbers.
Adding and subtracting two-digit numbers from two-digit numbers is a progression from adding or subtracting one-digit numbers. This obviously requires a higher level of skill, and many children may rely on using number lines or 100 squares to assist them.
