"A time-honoured way of learning how to do this type of activity is by first using building blocks such as Multilink or Lego. For example, using bricks of two different colours how many three brick towers can you build? Because the towers can be easily moved around it is possible to put them into order to spot duplicates or missing towers. The order could be determined by how many of each coloured brick are in each tower. It is understanding that there can be order to this task that makes it easier to do."
