LI: to replace bundles of objects with an object representing a certain amount.
Mr Wong's maths groups have been learning about Place Value. They have figured that tekau is an easy number to count in, especially for large numbers. Now they are learning to exchange bundles of tekau for a new object that is worth the same amount. First they did exchanges of sticks (tahi) for beans (tekau), then they counted how much worth they had accumulated.
This animation animates an exchange of tekau objects into tahi new objects that are worth tekau of the original.
