Students can:

Using straws and modelling clay students make skeletal models of square and triangular prisms.

Students can work in pairs to determine how many blobs of clay will be needed to show the vertices of each prism and how many straws will be needed to show the edges of each prism.

Students can use the examples to extend their understanding by making pyramids, hexagonal prisms, pentagonal prisms, etc. and complete the table to show the number of vertices and edges.

Teacher demonstrates how to draw 3D prisms using isometric grid paper and coloured attribute blocks. Select a block to form the base of your prism.

Students can then use the same strategy to draw pyramids.

Students individually draw the following objects using the two techniques discussed.

Ask the students to try to include dotted lines to show details which are hidden and use coloured pencils to show the base of each object.

In pairs, students use Geoboards and elastic bands to make 3D objects.

Instruct the students to use the elastic bands to initially make the base figures. Stretch other elastic bands to form the other edges of the 3D object. If they are making a pyramid, then the elastic bands that form the edges will all meet at one point on the geoboard.

ACMMG140: Construct simple prisms and pyramids.

MA3-14MG: Identifies three-dimensional objects, including prisms and pyramids, on the basis of their properties, and visualises, sketches and constructs them given drawings of different views.
