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

This is a level 3 geometry activity from the Figure it Out 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.

In this unit we develop the concept of angle to see that an angle may be constructed in a clockwise or anticlockwise direction. We see the effect of clockwise and anticlockwise turns on objects. We also think about corners of objects that are equivalent to quarter turns. We also think about whether a corner can be a half turn. These ideas are explored physically.

In this unit students take inspiration from several cubist artists then participate in a variety of art based activities to develop their knowledge of 2-dimensional shapes. They use their own language to describe their works and the shapes they have used.

In this unit we look at the beginning of the concept of angle.Here we are interested in students understanding quarter and half turns and to begin to see that ‘angle’ is something involving ‘an amount of turn’. These ideas are explored by using students’ bodies, toys, games and art.
