faces

This is a level 3 geometry activity from the Figure It Out theme series.

In this unit tessellations are used as an application of angle properties of polygons. Interior angle properties of polygons are used to justify the existence of the five platonic solids.

In this unit students make and investigate a variety of three dimensional shapes. By examining a wide range of shapes and looking at the relationship between the numbers of faces, edges and vertices they see whether they can “discover” Euler’s famous formula.

This unit involves a lot of exploration with three dimensional shapes and would be ideal as a lead in to the unit Building with Triangles, a level four unit which goes on to look at a group of polyhedra, the platonic solids, in more detail.

In this unit students will be having hands-on experiences with three-dimensional solid shapes. They will investigate the features of solid shapes and learn the names for them. They will be introduced to making nets for 3D shapes.
