Learning goals
- We are learning to solve problems that require finding a familiar fraction, decimal or percentage of a quantity, including percentage discounts, choosing the best strategies.
- We are learning to estimate and approximate solutions to problems involving rational numbers and percentages.
- We are learning to investigate and calculate percentage discounts of 10%, 25% and 50% on sale items, with and without digital technologies.
