Try and make a game of it  challenge them and have them challenge you.
Use humour  "I ate and I ate 'till I was sick on the floor"  "Eight eights are sixty four"
Involve them in everyday calculations that you do. At the shops  have them work out how much it will cost to buy different amounts of items  Is it cheaper to buy a 2 small boxes of cornflakes or 1 large one? How much will 6 apples cost? How much change should I get?
Try to make it relevant  How many sweets can they buy with their pocket money?
