1	Starter: finding percentages of quantities with and without a calculatorCalculator method (change the % to a decimal and multiply) ·    36% of 120 = 0.36 x 12 Main: increasing/decreasing a quantity by a percentage using multiplicative methods (use of a percentage multiplier is expected):Calculator method (change the % to a decimal and multiply) ·    Increase 60 by 15% = 115% of 60 = 1.15 x 60 ·    Decrease 60 by 15% = 85% of 60 = 0.85 x 60 ·    Using the % key on a calculator My Maths lesson Increase or decrease an amount by a % CB
2	Starter: compound interest without a calculator e.g. £550 is invested at 10% per annum compound interest, how much will there be after 2 years? Main: compound interest with a calculator (using multipliers) My Maths lesson - Slides 1-6 Teachers TV on Calculating Interest Worksheet to complete whilst watching Teachers TV Note that problems involving simple interest for more than one year will not be set but that compound interests on investments up to 20 years could be assessed.
3	Starter: In the last 2 weeks of a sale prices are reduces first by 30% and then by a further 40% of the new price. What is the final sale price of a shirt which originally cost £15.

Want pupils to appreciate that this is the same as 15 x 0.42 i.e. the shirt has actually been reduced by 58% overall. Example Questions JEE Successive Percentage Change CB Main: repeated percentage change including compound interest Plenary:  solving problems E.g. a seal colony is decreasing at 12% per annum. If the original population is 2000, after how many years will the population have fallen to half its original number? (Calculator)
4	Starter: expressing one quantity as a fraction or percentage of another (non-calculator) Main: expressing one quantity as a percentage of another including percentage change (calculator) Easiteach lesson ck Teachers TV on Percentage Change Worksheet to complete whilst watching Percentage Change Method: write change/original as a fraction then multiply by 100
