Real Life Problems • Go shopping with your child to buy two or three items. Ask them to work

out the total amount spent and how much change you will get. • Buy some items with a percentage extra free. Help your child to calculate

how much of the product is free. • Plan an outing during the holidays. Ask your child to think about what

time you will need to set off and how much money you will need to take. • Use a TV guide. Ask your child to work out the length of their favourite

programmes. Can they calculate how long they spend watching TV each day / each week?

• Use a bus or train timetable. Ask your child to work out how long a journey between two places should take? Go on the journey. Do you arrive earlier or later than expected? How much earlier/later?

• Help your child to scale a recipe up or down to feed the right amount of people.

• Work together to plan a party or meal on a budget. • These are just a few ideas to give you a starting point. Try to involve your

child in as many problem-solving activities as possible. The more ‘real’ a problem is, the more motivated they will be when trying to solve it.
