This resource handily introduces compound interest to more able KS3 groups and GCSE in the form of adding interest to a bank account. Other topics covered include percentages and decimal multipliers.
This resource is an investigation (with teacher notes and accompanying worksheets) which gets students to investigate whether how often interest is added to a bank account effects the total amount of interest.
The problem is so:
I invest £1,000 in a savings account at an interest rate of 3.1% p.a. for one year. What interval at which the interest is paid will get me the most money?
The students can then be guided to calculating the total amount of interest when it is added, daily montly etc. before being guided to an overall formula to solve the problem.

Bundle
Huge Set of KS3/GCSE Maths Foundation Whole Lessons and Investigations
A bundle which consists of 6 Powerpoints (on Constructing/Solving Linear Equations, Writing Equations and Formulae, Working out the Interior and Exterior Angles of a Polygon, Recognising and Drawing Nets of 3-D Shapes, Sample Space Diagrams and Standard Form). Each Powerpoint contains enough material for a whole lesson and has plenty of questions and worked examples.

Bundle
Huge Set of KS3/GCSE Maths Investigations
A set of 6 investigations (complete with teacher notes and worksheets) where students are set a challenging problem and work to find the solution. Each investigation should take up a whole lesson. The first investigation focuses mainly on probability and gets pupils to find the total possible number of half-time scores if given the full-time score, eventually finding a formula connecting the two. The second connects geometry and algebra, getting pupils to generate a formula which links the total possible number of triangles with a given perimeter. The third investigation gets pupils to discover the origins of square numbers whilst the fourth gets students to calculate the optimum rate (using compound interest) at which interest should be added to money in order to achieve maximum interest. The bundle concludes with a pair of investigations on triangular numbers, the first helping pupils to appreciate the properties of the sequence and the second which gets pupils to discover the derivation for the nth term of the triangular number sequence.
