Year 3 - Maths - measuring capacity

Year 3 have been working on units of measure. Today we investigated the capacity of different receptacles. Capacity is a measure of how much something can hold before it becomes full. A millilitre is the volume of one cubic centimetre. A thousand millilitres is a litre.

Capacity includes:

• The meaning of capacity and volume
• Discussion of appropriate units of capacity
• How to read scales and some common errors in reading scales
• Methods to work out the volume of a range of shapes
• Standard and non-standard units of capacity
• Activities to practise understanding of capacity and volume

First, we estimated how much water we thought a receptacle might hold. After that, we measured and worked out the difference. We found that our estimations improved as we progressed through the task.
