An angle is a measure of turn. It shows how far something has rotated. It is often displayed as the rotation between two line segments.

Rotate means to turn around a fixed point. It is an action or movement.

Clockwise is the direction that the hands of an analogue clock travel.

Anticlockwise is the opposite direction to which the hands of an analogue clock travel.

In this unit pupils will compare the size of angles where there is a clear visual difference and use the terms acute, obtuse and reflex when describing the size of angles or amount of rotation with relation to right angles using a unit called degrees. In the future unit pupils will use knowledge of shape properties to draw, sketch and identify shapes.

In the prior unit pupils completed and composed symmetrical shapes from two congruent shapes and investigate lines of symmetry in 2D shapes. In this unit pupils will compare the size of angles where there is a clear visual difference and use the terms acute, obtuse and reflex when describing the size of angles or amount of rotation with relation to right angles using a unit called degrees.
