About Subtraction Grids
Subtraction Grids is a mental maths game involving subtraction skills. It is suitable for 6 to 11 year olds and has two playing modes, where players need to select either one or two numbers from the grid to complete the subtraction calculation.
Each mode has 6 levels of difficulty and questions are randomised each time the games are played. The game is great for helping children improve their mental maths skills, especially those practising for SATs tests.
