Do your pupils realise that £14.99 is actually very nearly £15 or do they perceive it as only £14?
Use this worksheet to turn your pupils into savvy shoppers by showing how cleverly shops price items. A discussion is bound to start about pricing which can lead onto the psychology of shopping, used by companies to decide pricing and advertising messages.
This activity is taken from How to Dazzle at Oral and Mental Starters, a book containing 43 photocopiable ideas for use with pupils aged 11–14 who are working at levels 2–3 of the National Curriculum. The tasks are varied and teach pupils to understand and use mental strategies for addition, subtraction, multiplication and division in a range of contexts.
Each task is linked to the National Numeracy Strategy framework for Key Stage 3. They can be introduced to pupils in mixed ability classes or are suitable for pupils working in the lower sets in Years 7 and 8. The activities can also be used with Key Stage 2 pupils. There are three rapid response tests to identify strengths and weaknesses.
