The challenge
Next time you go to a shop or supermarket and spot a sale sign, stop.
Ask your child to consider whether this price is good value for money. Calculate the discount.
For example, let’s say a roast chicken costs $12. It's been marked down by one-quarter (or 25%). How much does it cost after the discount? If you bought the chicken at its new price, what could you afford to buy for dessert with the savings?
