Transformations : Maths

In our class we have finished learning about translations. Here is a mind map about what I have learnt.

Transformation: Translations

Task:
Explain what a translation is.
Explain how a vector works. What does it look like? What does the top number indicate? What does the bottom number indicate?
Give a real life example of when translation is used.

Translation in maths means moving a 2d shape around a grid. Translation in maths has something called a vector and a vector tells you how to move a shape up and down and left and right. A vector has brackets either side and the two numbers are stacked. The top number says the number has to go right or left. How you know this positive means right and negative means left. The bottom number means up or down. Same thing positive means up negative means down. We use lots of translation in real life like, a flying fox, elevator, a car and all sorts if they move up or down or left or right.

Rotating shapes

Task:
Answer these questions:

What 3 things do you need to say to describe a rotation?
- Where the centre of rotation is.
- How much it is rotated.
- Whether the rotation is clockwise or anticlockwise.

Explain what centre of rotation means
The centre of rotation is the spot where you rotate the shape. It can either be on the shape or outside of the shape.
