A degree is a unit of measure for angles.

Know that the angles in a full turn sum to 360 degrees and use this to solve problems

Maths

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.

Angles: compare, name, estimate and measure angles

Three and a half full turns is equal to {{ }}°.

 The code turns a character by the number of degrees shown.  Andeep wants the character to turn a full turn. What does he need to add to complete a full turn?

Sofia turns a full turn in two moves. The first move is 285°. The second move is {{ }}°.

A boat turns 45°, then another 80°. How many more degrees does the boat need to turn to complete a full turn? {{ }}° is needed.

Complete the sentence. A right angle is {{ }}°.

A polygon with four sides and four right angles. 	

A polygon with six sides and six vertices.

A polygon with eight sides and eight vertices.

This is a trapezium. Look carefully at the vertices and the angles inside the shape. Complete the sentence. The trapezium has {{ }} acute angle(s).

An angle greater than 180° but smaller than 360°

Which of these is the best estimate for the angle shown?

Sofia faces north. She rotates until she is facing north again. Sofia has rotated {{ }} degrees.
