Measurement makes no sense when it is isolated from everyday events. When you study Volume and Capacity with your students always link your discussion to real life examples. Before investigating millilitres, for example, ask each student to bring in an empty plastic litre container, preferable a transparent one. Use your school’s marked litre and millilitre resources to measure and then mark out where multiples of 100 mL come to in each container. Ask your students to compare what these multiples look like in different-shaped containers. Can they then predict where it will come to in a new container?
Encourage them to visualise, to imagine where the finish line will be. Look at where 200 mL orange juice comes up to in this marked container, for example. You need your eye to be level with the line to get an exact measure.
