Shopping Corrections

Michael-sHow do you make supermarket shopping bearable for everyone?

If you’re like me, you know full well how draining a visit to the supermarket can be if you are accompanied by children. But shopping is unavoidable. So we need a strategy.

My son, David, like most 8-year-olds, has a very good sense of ‘fairness’. He can spot an unfair situation from miles away! I decided to use this ‘gift’ as a way of keeping him entertained (and busy) while shopping.

Firstly, this is all about spotting mistakes.

Here are a couple of examples:


Why are the crisps 87p each, but £1.50 each if you buy 2?




This one is similar, but the price difference (mistake) is less obvious




And another from a different supermarket


How big a price drop do you need to qualify something as being in the ‘Sale’? 

With these ‘errors’ in mind, when we next went to the supermarket I challenged David to spot any mistakes with the pricing or the offers. He was intensely focused on this, and had to do a lot of calculating to test out the prices on the multi-buys and ‘special offers’.

This brings in lots of practice related to percentages, fractions and doubling and halving.

In the end, we didn’t find any mistakes in our local store, but he’s convinced he will and wants to look again next time we go!


If you test this idea out please post a comment below, especially if you have photos.

It’s up to you to decide whether or not you ask your children to help you ‘report’ the error to the supermarket manager!
