Our word of the week on Wednesday was icosahedron. Here are two great examples of our work. We had a 20 minute time frame and everyone was trying very hard to use dot points that gave just the key idea. Mrs S added some clip art images to illustrate our writing. The images were collected from creative commons sources.
An icosahedron is a 3D shape. It has 20 faces, 30 edges and 12 vertices. All the faces are equilateral triangles. It is one of a group of shapes called Platonic solids. There are only four other Platonic solids.
