About cross-number puzzles

Each clue is a sum, a product or another calculation, and its answer goes into the grid one digit per box. Where two answers cross they share a digit, which gives students a built-in check on their arithmetic.

Every puzzle has exactly one way to fill the grid. Choose addition clues, multiplication clues, or a mix of all four operations, and a 4×4 or 5×5 grid.
