Mountains Mystery Picture: Adding & subtracting to 10

Two grey mountains with snowy peaks, green hills in front and a yellow sun in the sky. The peaks appear first and the slopes grow wider row by row, so the landscape takes shape quickly.

Every number stays at 10 or below, with problems such as 4 + 5, 10 − 3 or 2 + 6. That covers the facts children need to know by heart before anything bigger: number bonds to 10 (7 + 3, 6 + 4), adding and taking away 1 or 2, and simple subtraction from 10. Because each answer is also a row number, the child has to read the result carefully and find the matching line, which quietly reinforces number order.
