Look at the fantastic boats designed and constructed by the children in First Class! Everyone described their boats, how they made them, why they chose the materials they chose, etc. It was so exciting to see them all float!
Of course a swimming pool is also very handy for learning about capacity in maths. We all estimated how many litres of water it would take to fill as far as the first ring of the swimming pool. Emily was the closest with her estimate of 99 litres but we were very surprised to learn that it actually took 240 litres!
We were also surprised to learn you can have all different shaped containers – wide, narrow, even cube-shaped – and they all measured exactly 1 litre! It was fun to measure with a variety of different containers and we definitely have a much better understanding of capacity after all our estimation and experimentation.
