Maths Quiz - Year 2 Calculation - Multiplication in any Order (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 recognising that the multiplication of two numbers can be done in any order.
By Year 2, children should be able to recognise the commutative property of a multiplication calculation. This means that the two numbers being multiplied can be done in either order, and still give the same answer. For example, 5 x 4 gives the same result as 4 x 5. They may use this skill to answer any questions involving times tables they are unfamiliar with (if they don't know 5 x 7, they may know 7 x 5 for instance). Cumulative property also applies when 3, 4 or any other group of numbers are to be multiplied. The calculation can be done in any order and the answer will be the same.
