Key learning points
- There are 1,000 ml in 1 l
- There are 1.000 g in 1 kg
- There are 10 dl in 1 l
- There are 100 cl in 1 l
- We can use knowledge of multiplying and dividing by 10, 100 and 1,000 to convert between units of mass and capacity.
Common misconception
Children may confuse when to multiply or when to divide when converting between units of measure.
Encourage children to think about which unit of measure is greater e.g. kg are greater than g. In a given amount, there will be fewer of the greater unit so we need to divide.
