Lesson 1
1A Rates
Use ratios, sharing, rates, speed, fuel use, flow rates, map scales, and practical unit conversions.
Lesson 2
1B Unitary Method
Find the value of one unit and scale to any quantity, including best-buy comparisons.
Lesson 3
1C Using Rates to Compare
Calculate and interpret rates in multi-step practical problems including speed, fuel consumption, flow rate and pay, applying rate formulas to find totals and compare options.
Lesson 4
1D Speed as a Rate
Calculate speed, distance and time, and convert between km/h and m/s.
Lesson 5
1E Distance–Time Graphs
Read speed from the gradient, identify rests and return trips, and find average speed from a distance–time graph.
Lesson 6
1F Fuel Consumption Rate
Use L/100 km rates to find fuel used, trip cost, and to compare vehicles.
Lesson 7
1G Heart Rate
Work with beats per minute: count-to-rate conversions, beats over time, and target training zones.
Lesson 8
1H Blood Pressure
Interpret systolic/diastolic readings, pulse pressure, and classify readings against thresholds.
