Maths Quiz - Year 2 Calculation - Multiplication and Division By 10 (Answers)
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 multiplication and division by 10.
Counting up and down in steps of 10 is an important and useful skill which helps with multiplying and dividing problems. It is usually practised regularly, in order for the skill to be fluent, and children are also taught to recognise that multiples of ten are even and end with '0'. Once the 10 times table is familiar, children will learn how to use the multiplication facts to solve division questions. For example, if they know that 2 x 10 = 20, then they may also recognise that 20 ÷ 10 = 2 or 20 ÷ 2 = 10.
