Here is another simple idea to help children understand measuring capacity. At this early stage non standard units of measurement are used eg a cup or a glass full rather than the standard litres and ml. You need a small saucepan and a selection of different cups, mugs, glasses etc. Try to avoid containers which are too small and would take more than 6 to 8 goes to fill the saucepan as it is very easy to lose count when doing this type of activity. One of the most important things to do is to have a guess, or estimate, as to how many cups will be needed and then see how close the guess was. There's never any need to guess absolutely correctly, just get closer with time and experience. Measure capacity (3)
