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.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
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.
