This presentation provides three days of teaching that cover the objectives:

  • Understand angles as an amount of turn and right angles as quarter turns.
  • Recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn.
  • Identify whether angles are greater than or less than a right angle.
  • Identify horizontal, vertical, perpendicular and parallel lines.

It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards.

Day 1
Show a clock face on the IWB. Where does the minute hand point at quarter past? At half past. Quarter to? Draw lines to split the clock into quarters. Shade a quarter section. This is a quarter of the clock face. What’s the angle between the lines? [a right angle; 90 degrees; 90°]. Draw a right angle. A right angle is a quarter turn. Repeat to identify a half turn and a three-quarter turn. Note that the clock hands turn clockwise. Turning the other way is anti-clockwise.

Day 2
Show a picture. Close your eyes. Turn it 90° clockwise. Open eyes, what have I done? You have turned it through a right angle, a quarter of a full turn. Repeat, turning it through 2, then 3 then 4 right angles, both clockwise and anticlockwise. 2 right angles is half a complete turn, 4 right angles a complete turn.

Day 3
Draw a square and a rhombus. Which is a square? All the sides in each shape are the same length. Observe how each angle in a square must be a right angle. Show a large set square and how a ‘square’ corner is a right angle. Compare angles in the square and rhombus against the right angle of the set square.

Day 4
Use the range of shapes on ‘Perpendicular and parallel lines’ (see resources) to explore lines that are vertical, horizontal, perpendicular and parallel. Look for examples of these around the classroom.

This teaching is part of Hamilton’s Year 3 Shape block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
