Coloured Cube 3D

Colour in the remaining faces of the nets of the cubes to match the rotating three-dimensional picture.

Cube Face Meetings

Visualise the cubes formed by the nets and paint the three faces meeting at a vertex.

Cubical Net Challenge

Find all the ways of painting the faces of cubes using only two colours.

Cylinders

Apply formulae for the volumes and surface areas of cylinders to answer a wide variety of questions

Dice Net Challenge

Faces, Edges and Vertices

Calculate the number of faces, edges and vertices on 3D Shapes.

Net or Not

Teachers might find the complete Shape (3D) Topic List useful.

A particular skill is required to be able to excel in this area of Mathematics. Spatial awareness is important for solving multi-step problems that arise in areas such as architecture, engineering, science, art, games, and everyday life. Children have varying abilities visualizing three dimensional relationships but these abilities can be developed through practical activities and working through mathematical problems. Breaking down three dimensional situations into smaller two dimensional parts in an important strategy for problem solving.
