It’s a rocket, but don’t tell! Finding each number practises reading and ordering numbers to 100, and the dashes in the key (like 22–29) practise counting on. Online, tap a colour and then the squares; “Show hints” tints the squares to colour.

How to solve this mystery picture
- Colour one colour at a time. Start with red: 5, 6, 14–17, 63 and the rest of its list.
- A dash means every number in between, so 3–6 is 3, 4, 5 and 6.
- Cross out each number in the key once it is coloured, so none are missed.
- Squares not in the key stay white.
