Using paper plates and a piece of wool or string. Children put a number of cubes on the plate as directed and then partition it into two sets. Ask how many they have on each side of the plate. Done as a group or even a class, note down different ways children have partitioned the original number. Using fingers to make numbers, tell them they must use both hands, ask them to show you a given number. Partitioning numbers is a lead into number bonds at this level.
