Nuffield - Working with Percentages

The activities in this resource look at percentage increase and decrease both individually, in combination and in reverse. It would make a good recap resource for those confident in working with percentages or a focus lesson for those in need of reinforcement.

+
Relevance to Core Maths qualifications

  • AQA
  • Eduqas
  • OCR

Suggested approaches

Students should be encouraged initially to think about different ways to calculate percentages with reference to a multiplicative method to give final amounts after interest has been added. Examples of real available savings accounts would be useful too.

+
Resources/documentation

In addition to this overview, there are:
• Detailed teacher notes (Word and PDF)
• Student information sheet (Word and PDF)
• Excel spreadsheet worksheet
• Excel spreadsheet worksheet – solutions

+
Relevant digital technologies

Access to Excel or an alternative spreadsheet programme is required. Calculators and internet access would also be useful.

Possible extensions

Students could be given a virtual sum of money to invest in one of the available savings accounts in order to maximise their return. Reference to ISAs, variable rates and long-term investments should be made.
