Translation is a transformation in which every point of a shape moves the same distance in the same direction. The act of moving is to translate.

Translation is a transformation in which every point of a shape moves the same distance in the same direction.

Describe translations of polygons drawn on a square grid

Maths

In this unit pupils will give directions from one position to another on a grid and move objects including polygons on a grid according to directions, and mark the new position. They will describe and draw polygons specified by translations. In the future unit pupils will describe positions in all four quadrants drawing and translating simple shapes and reflecting them in the axes.

In the prior unit pupils rotated two lines around a fixed point to make different sized angles. They identified vertices. In this unit pupils will give directions from one position to another on a grid and move objects including polygons on a grid according to directions, and mark the new position. They will describe and draw polygons specified by translations.

_____________ is a transformation in which every point of a shape moves the same distance in the same direction. 

What translation is needed to move the polygon from A to B? 

Lucas wants to translate the polygon from B to A. Which translation is incorrect? 

What can you mark on a shape to help you translate it accurately? 

Look at Sofia’s directions. Which image shows the correct translation?
