What you can do
- Choose one of 20 figures: shapes, houses, a rocket, a boat and animals such as a rabbit, dog, camel, shark, crab, seal and crocodile, or the figure's mirror image.
- Click next to a piece edge and type a task and its answer in LaTeX with a preview, and swap their sides with one button.
- “Fill with example” adds tasks on multiplying, dividing and adding rational numbers, and you can add decoy answers on the outer edges.
- Use the “Square” switch to show the pieces arranged in the square or in the figure; the pieces can be coloured or white.
- Print the square of pieces on A4 to cut out, with optional pages showing the figure outline and the solution.
