Common misconception
Children may confuse standard and non-standard units, for example measuring the height of a tower by counting the blocks rather than using a ruler to measure its length in centimetres.
Use prompts such as, 'How many centimetres tall is this tower?' and, 'The first part of the tower is 10cm tall.' to reinforce the use of centimetres as a standard unit of measure.
