Step 8 Objective
Know that translations, rotations and reflections preserve length and angle and map objects on to congruent images.
- 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?
Give pupils a grid with labelled congruent shapes formed from transformations: reflections, rotations, and translations. (See FTM(S)Y789 p. 205 - Acrobat pdf document (40Kb) for example.) Ask them to select pairs that are reflections and to describe the reflection, and similarly for rotations and translations. Use the probing questions.
