Lesson Details

Key learning points

There are 1,000 g in a kg
There are 1,000 ml in a l
There are 1,000 mm in a m
Information relating to measures such as length and mass can be presented in the form of tables or graphs.

Common misconception

When reading bar graphs with unmarked intervals, some pupils might assume each interval equals 1. In the case of the graphs presented in this lesson, the intervals go up in 100s, 200s, 250s and 500s.

Encourage children to apply their knowledge of converting a unit into 1,000 (such as 1 litre being converted into 1,000 ml) and then exploring its composition in 2, 4, 5 and 10 equal parts. Check the unmarked intervals by counting in those steps.

Keywords
