GAME GUIDE

Crack the Safe

A number puzzle with a secret inside.

Work out the multiplication code and enter it on the keypad. This is a chance to explain a strategy: use a known fact, draw equal groups or break a tricky calculation into friendlier pieces.

How to play

  1. Work out the whole answer before typing.
  2. Use the keypad to enter the code.
  3. If a try misses, check the calculation together.

Make one useful connection

After a turn, ask “How did you work that out?” Try an array, a known fact or real objects if an answer is uncertain. Moving, holding and remembering are extra skills; choose another interaction if those get in the way of the numbers.
