Lesson 1: Common Measures of Rate
| Section | Details |
|---|---|
| Objective | Use common measures of rate (hourly pay, exchange rates, flow rates, fuel consumption). |
| Activities | – Starter (5 mins): Ask: “If a worker earns $60 in 5 hours, what is the hourly rate?” – Main (30 mins): Teach definition of rate; practice calculations with money, exchange rates, and flow rates. Real-life examples: converting currencies, petrol usage. – Plenary (5 mins): Quick-fire quiz with short rate problems. |
| Resources | Worksheets, calculator, currency conversion examples. |
| Time | 40 minutes: 5 (Starter) + 30 (Main) + 5 (Plenary). |
| Homework | Solve 10 rate problems (hourly pay, exchange, flow). |
| Assessment | Worksheet: calculating and comparing rates. |
| Past Paper Practice | “A worker earns $72 in 6 hours. Work out their hourly rate.” |
Lesson 2: Average Speed and Other Rates
| Section | Details |
|---|---|
| Objective | Solve problems involving average speed and apply other measures of rate (pressure, density, population density). |
| Activities | – Starter (5 mins): Ask: “A cyclist travels 45 km in 3 h 45 min. Estimate their average speed.” – Main (30 mins): Teach speed = distance ÷ time. Solve word problems involving average speed, pressure, and density. Include units (m/s, g/cm³). – Plenary (5 mins): Students solve 3 speed/density problems on mini whiteboards. |
| Resources | Worksheets, calculator, diagrams of speed/density problems. |
| Time | 40 minutes: 5 (Starter) + 30 (Main) + 5 (Plenary). |
| Homework | 10 problems on average speed, density, and pressure. |
| Assessment | Worksheet: word problems on speed, density, and pressure. |
| Past Paper Practice | “A cyclist travels 45 km in 3 h 45 min. Work out their average speed.” |
