Math Puzzle with Reptiles and Amphibians — Grade 1

This Grade 1 worksheet hides a picture of frogs, snakes and a turtle behind a grid of small sums. The child solves each cell — some are addition, some are subtraction, all within twenty — and the answers tell which piece goes where, so the reptiles are reassembled only when every equation is worked out. The arithmetic is the real task; the picture is the reward, and it shows at a glance which cells still need another look.

The self-checking is the quiet strength of a solve-and-reveal puzzle: a wrong answer leaves the picture broken, so the child finds their own mistakes without every cell being marked. For within-twenty add and subtract practice that is ideal — it keeps a Grade 1 child working independently and honestly, because the picture only completes when the arithmetic does.

Children who like reptiles and amphibians get pulled straight into the solving — the hidden picture is a strong reason to finish every cell. When this feels easy, build another picture in math puzzle with shapes, or try math puzzle with camping gear. You can also browse every math puzzle worksheet or the whole reptiles collection for grade 1 — each one prints on a single page or plays online, revealing the picture as the answers go in.
