Practise Translating Points Involving Two Movements

In this activity, we will be learning how to describe movements on a coordinate grid.

 

Points can be shifted on a grid by moving them left or right and/or up or down.

This is called translating a point.

In maths, translate means shift or move.

 

Look at this diagram, showing points A, B, C and D on a set of x and y-coordinate axes.

 

 

A can be translated to B by shifting it 5 squares up.

 

We sometimes do two movements when we do a translation:

A can be translated to C by shifting it 5 squares to the right and 7 up.

 

We can write this in shorthand as R5 U7

 

Let's try a question together. 

 

Example

How can B be translated to D?

 

Answer

If we look carefully at the grid, we can see that B could be moved to D by shifting it 1 square to the left and 2 squares up.

The instruction would be L1 U2

 

Now it's time to try some questions like this yourself. 

 

 

Are you ready to have a go?
