# Year 1 Calculation - Addition and Subtraction Language

*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 developing the concept of addition and subtraction. *

In Year 1 children are taught the language associated with the number operations of addition and subtraction, which is wide and varied. It can also be confusing - for example, to find the difference between two numbers, it's possible to count up from the lower to the higher number (effectively adding) or count down from the higher to the lower (subtracting)! It's worth knowing the key language associated with the concept of addition or subtraction. This will be especially useful when tackling word problems.
