Sliding or moving a shape without rotating or flipping it means to translate.

Solve problems involving marking and translating points in the first quadrant on a coordinate 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.

Coordinates

Jacob wants to translate his shape 3 squares up. Which statement is correct? 

Sofia wants to translate her shape 4 squares left. Which statement is correct? 

 Which coordinates will produce a rectangle? 

Sofia’s triangle has the coordinates (1, 2) (3, 2) and (2, 4). She wants to translate it 1 square down. What will the new coordinates be?

Sofia translates the shape 1 place right and 2 places up. Match the original coordinates to the new coordinates.

What is the missing coordinate for vertex B? Remember to write the coordinate using brackets and a comma.

Which coordinate do we write first when describing a position on the coordinates plane? 

Question: What is the coordinate of the dot?

The polygon is translated 1 square down. Write the new coordinate of vertex A remembering brackets and a comma.

Translate the polygon 3 squares right. What are the new coordinates of the vertices? 

The polygon is translated 1 square right and 2 squares down. Write the new coordinate of vertex A remembering brackets and a comma.
