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?
How many triangles can you make using sticks that are 3cm, 4cm and 5cm long?
Make a cube out of straws and have a go at this practical challenge.
60 pieces and a challenge. What can you make and how many of the pieces can you use creating skeleton polyhedra?
