Christmas tree Mystery Picture: Adding & subtracting to 10

A green Christmas tree with a yellow star on top, red ornaments and a brown trunk. The layered branches grow wider row by row, so children can watch the tree take shape as they color.

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.
