Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work" Comment recorded on the 19 October 'Starter of the Day' page by E Pollard, Huddersfield: "I used this with my bottom set in year 9. To engage them I used their name and favorite football team (or pop group) instead of the school name. For homework, I asked each student to find a definition for the key words they had been given (once they had fun trying to guess the answer) and they presented their findings to the rest of the class the following day. They felt really special because the key words came from their own personal information."

Level 1  Simple Interest
Level 2  Compound Interest
Level 3  Exam Style Questions
Simple interest: I = P × R ÷ 100 × T
Compound interest: I = P(1 + R ÷ 100)^{T} − P
I is the amount of interest earned by the investment.
P is the principal, the amount originally invested.
R is the rate of interest expressed as a percentage.
T is the number of years the amount was invested for.
If you are following a syllabus that allows the use of a graphic display calculator you could use the Finance Solver to help calculate answers for the compound interest questions.
