Unit 1- Percentages

Unit Objectives
​
Prior Knowledge/For Review – Students should be able to:
  • Find one quantity as a percentage of another (eg percentage score) (Video 1.01)
  • Use the unitary method to find any percentage of a quantity with a calculator (Video 1.02) (Video 1.03)
  • Increase and decrease by a percentage (Video 1.04)
  • Use multiplicative method to find percentages of quantities (Video 1.05)
  • Use multiplicative method to increase and decrease by a percentage
  • Find percentage changes (Video 1.06)
IGCSE Core Learning Objectives – Students should be able to:
  • Calculate equivalence between decimals, fractions, ratios and percentages (Video 1.07)
  • Calculates percentages including applications such as interest and profit, including simple and compound interest (Video 1.08) (Video 1.09)
IGCSE Extended Learning  Objectives – Students should be able to:
  • Solve reverse percentage problems (Video 1.10)
