Understanding advertising
Lesson details
Learning outcome
I can analyse promotions and marketing claims.
Key learning points
- Promotions do not always offer the best value for money.
- Advertisements often use data to make their point.
- The validity of the data and conclusions should not be assumed.
Keywords
Proportion - Proportion is a part to whole (sometimes part to part) comparison.
Unit - A unit is one of something that defines the 'one' you are counting in.
Common misconception
Pupils may think that it is always best to buy a 'deal' as deals are always a good thing.
Throughout the lesson it is demonstrated that a deal or promotion may not always be right for every customer. Is a deal worth it if you don't need to buy that much?
Teacher tip
You may wish to ask your pupils to investigate prices/promotions at different shops which sell the same products. If each pupils picks a different item, the class can then compare which shop is saving the customer more money across all items.
