Task Instructions

In shops with lots of ice-cream flavours there are many different flavour combinations, even with only a 2-scoop cone.  With 1 ice-cream flavour there is 1 kind of 2-scoop ice cream, but with 2 flavours there are 3 possible combinations (eg vanilla/vanilla, chocolate/chocolate, and vanilla/chocolate).

  • How many kinds of 2-scoop cones are there with 10 flavours?
  • Create a poster that represents your group’s thinking.
