Plotting and Interpreting Real-World Graphs
MA17-01
This lesson is coming soon.
In this lesson
Read a value off a real-world graph (travel, conversion or simple kinematics) and correctly translate a calculated value into a plotted point on that graph.
What it covers
- Reading a value (distance, time, cost, temperature, speed) off an already-drawn real-world graph
- Plotting a new point onto a real-world graph once a value has been calculated (e.g. 'the taxi reaches the airport at 10:57 — mark this on the graph')
- Travel graphs (distance-time): reading off stationary sections (flat = stopped), direction of travel, and total journey time
- Conversion graphs (e.g. currency, units, temperature) used to convert between two quantities by reading across and up
- Simple kinematics graphs presented in a real-world story (a car speeding up, a lift stopping) read descriptively, without calculating a numeric gradient
- Using given graphs to find an approximate solution to a stated real-world problem

For teachers
This GCSE Maths lesson teaches plotting and interpreting real-world graphs. By the end, students should be able to read a value off a real-world graph (travel, conversion or simple kinematics) and correctly translate a calculated value into a plotted point on that graph. It works through two worked examples and the mistakes examiners report.
