Lesson video

I'm Miss Davies, and in this lesson we're going to be translating and describing the movement of an object in a horizontal and vertical direction.

Translating is the movement of an object.

It can go in any direction.

We're going to start by moving horizontally and vertically.

We're going to move or translate shape A five squares to the left and label it as B.

That has been moved five squares.

Let's label it as B.

We're now moving shape A three squares up and labelling it as C.

Finally, we're moving shape A six squares to the left and then four squares up and labelling this as D.

Here are some questions for you to try.

Pause the video to complete your task and resume once you're finished.

Here are the answers.

Make sure that the dimensions of the shapes stay the same.

They are only being moved.

We have been asked to describe the translation from shape R to shape S.

This is asking us how many squares across and up or down shape R has moved to be in the position of shape S? If we count from any of the vertices of shape R, we can see that we go across six squares to the right and two squares down.

What do you think the translation would be from shape S to shape R? It is six squares left and two squares up.

Here are some questions for you to try.

Here are the answers.

Shape C to shape D has been moved five squares to the right and one square down.

Shape D to C has been moved five squares to the left and one square up.

Make sure you're going in the correct direction that is stated.

Here are the answers.

Eric has described the translation of shape Y onto shape X, X onto Y is four squares to the right and one square down.

Here are the answers.

Only the final statement is correct.

Make sure that you're comparing the same point of each shape.

That's all for this lesson.

Thanks for watching.
