This week we talked about capacity in Maths. The students learned that capacity is the amount of liquid a container can hold. They also learned about the units we use to measure capacity, namely litres (L) and millilitres (ml). They learned that we use ml to measure small quantities and L to measure large quantities. They also learned that 1 litre is equal to 1,000 millilitres. The students also practiced making estimations of the capacity of different containers as well as reading different amounts of liquid on a scale. They did all this by means of hands on activities since we used different containers filled with water. We put green food colouring in the water so they could read the capacity clearly on the scale on each of the different containers. We estimated and poured different quantities of coloured water in different sized containers. We experimented with different containers to see if they could hold more or less than 1 litre. We even saw how many of a particular container were needed to fill up a larger container. For example, they learned that they needed 2 500ml containers to fill up a 1litre container. The students also saw different sized 1 litre containers to learn that even though they looked different, they all had the same capacity. It was a fun learning experience and the students enjoyed pouring the coloured water in the containers!
