I can use my knowledge of shape properties to draw shapes accurately using rulers and protractors.

Lesson details

Key learning points

  1. A protractor is used to draw and measure angles accurately.
  2. Read the scale from zero on a protractor to draw and measure angles accurately.
  3. Read the scale from zero on a ruler to draw and measure accurately.

Common misconception

Pupils can find protractors tricky, sometimes drawing the wrong angle because the outer scale has been used rather than the inner-scale, or vice-versa.

Emphasise estimation through knowledge of angle types. Model discussion of whether an angle is acute or obtuse and use this knowledge to identify which value on which scale is the measurement.

Keywords

  • Protractor - A protractor is an instrument used in measuring or drawing angles.

Consider how confident pupils are in using a protractor independently. Independent tasks could be scaffolded further by adapting angles to measure in multiples of 5 or 10
