Nuffield Mathematics teaching resources are for use in secondary and further education

Level 3 Personal finance

Credit cards

Students use a recurrence relation to work out how long it takes to pay off a credit card loan and how much it costs. They can use a graphic calculator and/or spreadsheet to do the working.

House price moving averages

This activity uses UK house prices to introduce moving averages and weighted moving averages.

Annual Percentage Rate (APR)

Students calculate the APR in the simplest case where a sum of money is borrowed at a particular time and paid back, with interest, in a single payment at a later date.

APR with more than one instalment

This resource shows students how to check and then find the APR in more difficult cases when a loan or debt is repaid in several annual instalments.

Measuring inflation using Laspeyres index

Students use a formula to calculate Laspeyres index to obtain a measure of price changes during different periods of time. They use a spreadsheet and/or a calculator to do the working.

Working with percentages

Use this activity to check what percentage methods students use, and to encourage them to use efficient multiplier methods.
