Wrap it Up

The Ministry is migrating nzmaths content to Tāhurangi.           
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

This activity gets students to apply translational and rotational symmetry to create freeze-type patterns. The method suggested uses a printing block.
The patterns created by translation need to preserve the orientation of the figure. For example:

grid1.

By contrast, the patterns created by rotation involve a change in orientation. For example:

grid2.

Students may find that they can apply translation and rotation in combination. For example:

grid3.
Another way of making patterns by reflection is to cut a tracing block from a square of card. Note that it is wise to mark the original corners of the square before cutting to help keep track of the original shape. For example:

rotatecorners.


The pattern can be duplicated across the whole page by repeated reflection.
