Draw polygons specified by coordinates in the first quadrant

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

Sofia thinks of a shape for Lucas to draw. She gives him six coordinates to mark the vertices. What shape must it be? 

Write the coordinates of the circled vertex. Remember to write the coordinates using brackets and a comma.

Sofia wants to draw a rectangle. What is the missing coordinate? Remember to use brackets and a comma.

Sofia wants to draw a trapezium. Identify the coordinates so that she is able to mark the final vertex. 

Lucas plots out a triangle. He moves the vertex marked at (1, 5) to (3, 4). What shape will it now be? 

Sofia describes a polygon using coordinates to mark the vertices. She gives Lucas exactly 4 coordinates. What shape can it not be? 

A 2D shape made up of three or more straight lines.

A set of values that show an exact position.

Match the definitions to the correct word.

What is the name of the shape which is to the left of the triangle?

What is the name of the shape which is to the right of the square?

What is the coordinate of the vertex marked with a dot?
