Four parts, one coherent lesson
Every part returns to one picture: the speed-time side of the twin-graph poster, read two ways, gradient and area.
Lesson plan
A timed 45-minute sequence: a simulation-led hook, the gradient and area methods, Pairs Check, a Gallery Walk, and an exit ticket. Extended objectives, examiner traps, differentiation and a timing and contingency note.
Worksheet and answers
Six original Extended questions on gradient and area from a speed-time graph, with a full worked answer key.
Slides
Ten editable slides with accurate diagrams: the two readings, the area split into shapes, and a full worked example.
Pairs Check activity
A problem set and a gallery task with answers, and a full step-by-step facilitation guide for both Pairs Check and the Gallery Walk.

This bundle pairs with the student topic pages Motion graphs and Acceleration, and the hook runs on the site simulations Distance from a Speed-Time Graph (area) and Acceleration from a Velocity-Time Line (gradient).
Two readings from one line
The simulations split the speed-time graph into its two Extended readings: an area that matches a true distance, and a line whose slope is the acceleration. The lesson then makes both methods routine, the large triangle for the gradient, and the split into a triangle and a rectangle for the area.
Pairs Check has learners solve, coach and check in turn, and the Gallery Walk exposes them to different correct layouts and common slips. The activity ships with a full facilitation guide for both structures, and the traps it pre-empts are the classic ones: reading the area as a speed, and forgetting a deceleration is negative.
