Mr Burke, Ellis's dad, came into talk about how he uses money in his job as a bus driver. He has to use a lot of maths when he takes money from people paying for their tickets on the bus. He has to add up the price of the tickets they need. Then he has to take the money but if they don't have the correct amount he then has to calculate their change. He has to be very careful not to make a mistake so he has to know his number bonds very well. He also has to know which coins to take out of his special money dispenser so that he can make the correct amount of change.
