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?
Probing questions
What information do you need to do a reflection? A rotation? A translation?
What stays the same and what is different when you reflect a shape? When you rotate it? When you translate it?
If I had a shape and rotated it and then reflected it would that be the same as reflecting it and then rotating it?
Sketch a quadrilateral that has just one line of symmetry; or two lines, three lines, four lines, no lines.
What is the order of rotational symmetry for each of these quadrilaterals?
