Vincent and Tara are making triangles with the class construction set. They have a pile of strips of different lengths. How many different triangles can they make?

Let's say you can only use two different lengths - 2 units and 4 units. Using just these 2 lengths as the edges how many different cuboids can you make?

60 pieces and a challenge. What can you make and how many of the pieces can you use creating skeleton polyhedra?

How many triangles can you make using sticks that are 3cm, 4cm and 5cm long?

Given a 2 by 2 by 2 skeletal cube with one route `down' the cube. How many routes are there from A to B?

Make a cube out of straws and have a go at this practical challenge.
