The purpose of this activity is to support students in measuring length with scales in situations where they must interpret the space between units.
Present simple scenarios in which students, working in pairs, need to interpret the space between marked measurements. Restrict the examples to centimetres at first, such as:
Present students with a ruler from Copymaster 1 that shows centimetres but not millimetres.
How long is the pencil in centimetres?
Discuss imagining marks on the scale to establish a measure.
Two main methods are likely to be evidenced in this discussion:
