About Secret Code
A key at the top shows which number hides behind each colored shape, for example a star for 4 and a heart for 7. Your child decodes the shapes below, then adds them or reads them as one bigger number, and picks the right answer from the tiles.
How to play
- Look up each shape in the key to find its number.
- Add the numbers or put the digits together, then tap the answer.
- With a keyboard, press 1, 2, 3 or 4 to pick an answer.
What your child practices
