You could also have some fun practising your money skills! Parents you could set a price list for snacks and meals, and children you could calculate how much you have spent and your change from a £10 or £20 note. Or if you have younger brothers and sisters, how about setting up a cafe or shop? Set up your own menu or price list, and work out how much your 'customers' spend.
How about emptying out your money box, purse or piggy bank and working out how much you have saved?
