Maths Quiz - Year 1 Calculation - Multiplication Using Arrays (Questions)

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 multiplication using arrays.

Multiplication using arrays is a way of organising the numbers in a visual way in order to understand how repeated addition is the same as multiplication. Using an array to visualise a problem also highlights how the order of the multiplication can be reversed to give the same answer. For example, 2 x 4 gives the same answer as 4 x 2.
