What age would you expect a child to recognise and be able to work out how much money they had.
I recently came across an 8yr old who had 80p in coins (50p,20p and 10p) but had no idea how much they had or what they could afford to buy with it.
I was a little surprised.
I can understand not being able to add up but to not know the names and value of coins or notes would worry me.
I suppose that if the parents use plastic for every payment they make they may not have been exposed to many cash transactions, but maths lessons include a large amount of cash based problems to introduce them to decimals.
