Mark the position of points specified by coordinates in the first quadrant of 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

A set of values that show an exact position. 

Match the definition to the correct word.

Match the different parts of the grid to its name.

True or false? When plotting points, you must go across and then up. You cannot do it the other way around. 

What is the coordinate marked on the grid? 

Sofia and Jacob are playing a game of Alien Treasure. Jacob says ‘My treasure is at the coordinate (1, 2).’ Which colour is his treasure? 

What are the coordinates where the lines cross?

Look at the table. Which line is horizontal?

Look at the table. Which line is vertical?

Complete the description. The polygon has been translated {{ }} squares right from A to B.

The polygon has been translated {{ }} squares up from A to B.

Describe the translation of the polygon from A to B.

2 squares left. {{ }} squares down. 

Sofia translates a polygon 5 squares left and 3 squares down. Describe the translation to get it back to its original position.
