Tim had nine cards, each with a different number from 1 to 9 on it.
He put the cards into three piles so that the total in each pile was 15.
Hints and Tips
- Make your own set of 1 to 9 cards to help you.
- Think about the total of the whole set of cards.
- You don’t have to have the same amount of cards in each pile. Only the total of each pile should be the same.
- Use attempts that don’t work to help you try again!
