How to play

• Each player gets dealt 7 cards.

• Before starting the game, players attempt to make part-whole triangles from the cards they have been dealt.

• Players then take turns in trying to make part-whole triangles.

  • Players may take a card from their opponents unused pile or from the pile in the middle.

  • Players need 3 cards in their unused pile at all times.

• The winner is the person to make 6 part-whole triangles or the person with the largest number of triangles once all the cards have been used.

Discuss/reflect

• Without moving the 13, how many part-whole triangles can you make? How will you know you have found them all?
