What 3 things do you need to say to describe a rotation?
1. Where the centre of the grid is.
2. How much has it turned.
3. It is either clockwise or anticlockwise.
Explain what centre of rotation means.
In a rotation, the point that does not move.
Now use these 3 things to describe the rotation on Page 1 of the myimaths lesson (i.e. describe the rotation of the triangle)
The triangle rotates 90 degrees clockwise.
