Translations
Explain what a translation is.
Translation is the movement of a shape on a grid and you use co-ordinates and to get the co-ordinates you use vectors.

Explain how a vector works. What does it look like?
indicate?
(3)
(8)
This is a vector. What is means as that these are what you use to know the co-ordinates and the top number means if you go left or right and how far and the bottom number indicates if the shape goes up or down. The rule is if the top number is a negative then the shape goes left and if it's not the shape goes right. The same applies with the bottom number, negative is down.
Give a real life example of when translation is used.
An example would be a forklift translating creates and boxes to new locations.

Rotating Shapes
What 3 things do you need to say to describe a rotation?
1. Where the centre of the grid is
1. Where the centre of the grid is
2. How much has it turned
3. Whether the rotation is clockwise or anticlockwise
Explain what centre of rotation means
The centre of rotation is the spot that you choose to rotate the shape from. For example: if I have a square I could choose to rotate the shape form either the centre of the shape or from one of the corners.

Now use these 3 things to describe the rotation on Page 1 of the myimaths lesson (i.e. describe the rotation of the triangle)In the MYiMATHS lesson the have a triangle and rotate it 90º
The triangle was on its side and then when it rotated 90º it was facing upward.
The triangle's point was in the co-ordinates of (-4,5) then when it rotated 90º the point was in the
co-ordinates of (5,5)
