We where set a challenge to build a 3D shape. Which was called a pentahedron. Then we were told to make another 3D shape, out of the pentahedrons. It was very challenging for all the groups to work out the shapes and where to put them, but in the end it was an icosahedron.

You needed 20 pentahedrons to make the icosahedron. The wonder diamonds completed the task first. All the other groups followed soon after. We then had to count how many faces, points and edges the icosahedron had.

Overall the icosahedron had 20 faces, 15 points and 30 edges. We thought the task was hard but fun at the same time. We are now using then to play maths games, to help us improve our times tables.
