Rainbow Reveal is a collection of four colourful KS1 maths games where children clear answer clouds as the sky brightens and a rainbow is gradually revealed. The shared format keeps the focus on the calculation while giving each correct answer a clear visual reward.
Begin with addition and missing-number addition, then move into subtraction and finding the missing amount taken away. Every version includes the optional Magic Rainbow for visual maths support, helping children work through the calculation without interrupting the game flow.

Missing Number Addition
Find the missing number in addition calculations, then clear the matching answer cloud. The Magic Rainbow provides optional visual clues while children develop number-bond and missing-number reasoning.

Subtraction
Practise subtraction within 20 and progress to bridging through 10, subtracting tens and ones, and two-digit calculations. Correct answers clear the clouds while the Magic Rainbow can model the subtraction visually.

Missing Number Subtraction
Work backwards to find how many were taken away. The Magic Rainbow shows the starting amount, what remains and the missing amount removed, helping children make sense of missing-number subtraction before choosing an answer cloud.
