Step 6 Objective

Transform 2-D shapes by simple combinations of rotations, reflections and translations, on paper and using ICT; identify all the symmetries of 2-D shapes.


What if pupils find this a barrier?

Where necessary, use cut-out shapes to enable physical transformations.

When doing translations consider the image of a point rather than the whole shape and show that in the translation of a shape the image of every point defines the translation.

Have plenty of tracing paper so that pupils can move things around easily. Use cm-squared paper.

Sometimes it is easier to fit diagrams to coodinate axes.

Use ICT drawing packages, dynamic geometry or LOGO.
