Year 1 have been learning to compare, describe and solve practical problems for:
capacity and volume [for example, full/empty, more than, less than, half, half full, quarter]. They also learn to measure and record using non-standard units.
Year 2 have been learning to choose and use appropriate standard units to estimate and measure capacity (litres/ml) to the nearest appropriate unit. They also learnt how to compare and order volume/capacity, and record the results using >, < and =.
