Today, we started our new maths topic, capacity. We took the opportunity of the good weather to do some outdoor learning. We discussed that 1000ml = 1L and that we can read how many litres or ml something is on the side of our containers e.g. milk cartons.. P2/3 were introduced to the litre as a standard unit. As a class we discussed the different language around capacity e.g. half full, nearly full, empty and so on and we looked at which containers hold more by showing a tall and thin tube and a wide and small tub.
P2 worked in a small group to compare the pairs of containers to find out which hold more / less and they chose 3 containers to find which holds the most/least amount of water.
P3 went into small groups and each group had options of some containers, a litre jug and a set of cards labelled 'holds about 1 litre', 'holds more than 1 litre' and 'holds less than 1 litre'. The pupils took each container in turn and they estimated and measured what holds more than, less than or about one litre.
