Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Activity

In this activity, students need to draw nets of the buildings and then make them into models. Although the Pyramid Plaza net is the one shown on the page, the more simple net of the Capital Chambers building could be a starting point for a discussion about how to draw the nets for the other buildings.

Key questions to prompt students with include:

  • What shapes will you need to add to the Capital Chambers net to make nets for the other buildings?
  • Look at the Capital Chambers net. Where do you think the shapes to make the other nets will need to go?

There is a definite pattern that emerges with the nets, and there are several possible places where students might place the shapes for the roofs.

Patterns

  • The floor of each building can be attached to any side.
  • The different shapes are attached alternately at the top of the net. (See the diagrams in the answers.)
  • The top of the building can be completed in a variety of ways, for example:
    – Pyramid Plaza – two small rectangles. These could be placed separately or on top of one another. Two small triangles are also needed.
    – Civic Centre – one large rectangle and two rounded shapes.
    – Colonial House – two large squares, which can fit on top of each other. Two small rectangles are also needed.

Let students experiment with different nets. The important point to get across in this activity is that different nets can achieve the same result.
