Little Juan needs new things for school. His mother takes him shopping and buys goods costing 15p. She only has a 20p piece, so what should she do? El Nombre explains that when the amount you give to pay is greater than the amount you owe, you need to be given change. He also explains that one 5p piece is worth the same as five 1p pieces.

This clip is from:
Numbertime, Change from 20p

Pupils can watch the clip and then be given coins. Half the class could be given 20p pieces and the other half smaller value coins. Pupils would then get into pairs, with each pair having one 20p piece holder and one smaller change holder. Once this is done, the teacher could display on the board a price lower than 20p. In their pairs, pupils would have to get together the correct amount of change for that product when 20p is paid for it. This could be repeated multiple times, each time with a different price being displayed on the board.
