The aim of this task is to develop students’ spatial visualisation.

The greatest difficulty students have is visualising the cubes that they cannot see. To help with this, have students make the completed building, including the missing piece, before attempting to draw it. Throughout the process, encourage students to communicate their understandings and ideas. To further reinforce understanding, the drawings can be done on isometric dot paper.

From this initial drawing, students can go on to design their own cube buildings:

Encourage students to make models from other students’ designs. This helps students to consolidate their understanding of three-dimensional shapes and encourages ownership of ideas.
