Co-ordinates & Translations

The objective of this lesson is: To plot a shape and translate it for a given rule. To work out the translation from its original position to a new position. To give the coordinates of a given shape after a translation without drawing the translation.

Translations 1. Translate A Move A 4 squares forward then 3 squares up. 1 2. Translate A Move A 7 squares backward then 6 squares down. 2

Translations 3. Translate A Move A 2 squares forward then 6 squares down. 4. Translate A Move A 6 squares backward then 2 squares up. 4 3

Translations In the diagram above the shape labelled 1 can be obtained by a translation. Give the translation in the form Number of squares forward. Number of squares down. Translation 1234567 x 1 1 2 3 4 y 0 7 6 5 4 3 2 1 A 2 3 4 1 2 2 7

Translations In the diagram above the shape labelled 2 can be obtained by a translation. Give the translation in the form Number of squares back. Number of squares down. Translation 1234567 x 1 1 2 3 4 y 0 7 6 5 4 3 2 1 A 2 3 4 1 2 2 5

Translations T Translate the shape T using What are the new coordinates of the triangle? How can you work them out without drawing a grid or the shape?

Translations Translate the shape T using Just add 8 to the x coordinate and take 6 from the y coordinate. How to work out the coordinates without drawing a grid or the shape? Explain in your exercise book how to get from the left hand coordinate to the right hand coordinate.

Plenary You should be able to give the coordinates of a given shape after a translation without drawing the translation. You should be able to plot a shape and translate it. You should be able to look at two shapes and work out the translation required to get from one to the other.
