These addition grids enable children to understand the commutativity of addition as they find the sum of numbers at the top of each column and start of each row.

This set of addition grids will see learners adding multiples of 100 to 4 digit numbers. The questions increase in difficulty as the worksheet progresses; starting with adding a hundreds to a multiple of 1,000, then multiples of 100 and 10, before progressing to adding hundreds to any 4 digit number (firstly without exchanges and then with exchanges).

There are 36 questions to answer in total.
