Give directions from one position to another on a 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 polygon is a 2D shape made up of three or more straight lines.

Move objects including polygons on a grid according to directions and mark the new position

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

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

Horizontal is side to side, like the horizon.

Vertical is an up-down direction or position.

Draw polygons specified by translations

The origin is where the x-axis and y-axis cross.

Coordinates are a set of values that show an exact position.

Mark the position of points specified by coordinates in the first quadrant of a coordinate grid

The x-axis runs horizontally (left-right) through zero.

The y-axis runs vertically (up-down) through zero.

The origin is where the x-axis and y-axis cross. It has the coordinate pair (0,0).

Write coordinates for already marked points in the first quadrant of a coordinate grid

A vertex is the point where two lines meet. The plural is vertices.

Draw polygons specified by coordinates in the first quadrant

A vertex is the point where two or more line segments meet. The plural is vertices.

Complete polygons with missing coordinates

A vertex is the point where two or more lines meet. The plural is vertices.
