Description

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.

This unit builds on and formalizes knowledge of angles as a measure of turn and as properties of 2D shapes. Pupils classify and define acute, obtuse and reflex angles, identifying them in shapes and using them to classify shapes. They calculate missing angles, using knowledge that there are 360 degrees in a full turn and also use an angle measurer or protractor to measure and construct angles. This will be built on as they learn to draw construct shapes in the future.

  1. Review understanding and identification of right angles
  2. Review understanding of angles as a measure of turn
  3. Use the terms acute, obtuse and reflex when comparing angles to a right angle
  4. Use the unit of degrees as a standard unit to measure angles
  5. Describe static angles using the standard unit of degrees when compared to a right angle
  6. Describe rotations using the standard unit of degrees when compared to a right angle
  7. Estimate acute and obtuse angles using the standard unit of degrees
  8. Know that the angles in a full turn sum to 360 degrees and use this to solve problems
  9. Know that the angles at a point sum to 360 degrees and use this to solve problems
  10. Angles in quadrilaterals
  11. Know that the angles on a straight line sum to 180 degrees and use this to solve problems
  12. Angles in triangles
  13. Measure the size of angles accurately using a protractor
  14. Draw angles accurately using a protractor
  15. Reasoning about angles in polygons

  • Identify right angles
  • Compare angles using visual tools
  • Estimate angle size using known benchmarks
