This morning in Maths we completed some more learning about volume. We learnt the word volume meant ‘how much room is inside a container’ and we measure it in litres and millilitres. We looked at a jug and found out that there are 1000ml in 1l. Miss Williams showed us how to fill the jug accurately with 1l then pour it into a container to find out whether the container has a volume of more than 1l or less than 1l. We practised using the < and > signs also.
We then worked together outside to sort some containers. We had to work together as a team and take turns sensibly. We filled our jug with 1l of water then tried to fit it inside the container. We found out that if we had more water left in the jug when the container was full, the volume of the container was < 1 l. If we had no water left over and there was still room inside the container, the volume was > 1l.
Some children thought they had found containers which held exactly 1l but when we checked they held less. Miss Williams found one she thought held about 1l and Nicholas explained how we could check. He said if we measured a litre then poured all the water into the container so the jug was empty and the container was full, we would have found it holds 1l. It turned out Miss Williams was right! But did she estimate or did she just look on the label?!
