Here’s a great game for developing mental maths skills.
Children have to roll three dice. They use the numbers they roll to make as many totals as possible.
For example, suppose they roll 1, 3, 5, they could then make these totals
3 x 5 + 1 = 16
5 — 1 — 3 = 1
13 x 5 = 65
3 + (1 x 5) = 8
They can use any operation sign ( + - x ÷ ) and also brackets to show the order of operation.
As they make a number, they colour it on the grid.
Eventually they will not be able to make any more numbers. At this point, roll the dice again and use a different colour.
The challenge is to complete the grid, making every number whilst using as few colours and as few rolls of the dice as possible.
Is it possible to complete the whole grid? Which numbers were hardest? Were any numbers impossible to make?
Ideal for upper KS2 or lower KS3
