Four parts, one coherent lesson
Every part returns to one tool: speed = distance over time, read as the gradient of a distance-time graph, with velocity adding a direction.
Lesson plan
A timed 45-minute sequence: a simulation-led hook, v = s over t, Rally Coach, a calculation check, and an exit ticket. Objectives, vocabulary, examiner traps, differentiation and a timing and contingency note.
Worksheet and answers
Six original questions on speed, velocity, average speed and unit conversion, with a full worked answer key.
Slides
Ten editable slides with accurate diagrams: the round trip, speed as a gradient, conversions, and the average-speed trap.
Rally Coach activity
Two matched problem sets with answers, and a full step-by-step facilitation guide: roles, a teacher script, coaching prompts, and troubleshooting.

This bundle pairs with the student topic page Speed and velocity, and the hook runs on the site simulation The Round Trip Trap: distance and average speed grow while velocity carries a direction and can return to zero. That contrast opens the lesson.
One tool, practised until fluent
The simulation sets up the difference between speed and velocity, then the lesson builds one tool, v = s over t, read as the gradient of a distance-time graph, which also introduces the unit's twin-graph poster.
Rally Coach then gives step-by-step paired practice, and because the activity ships with a full facilitation guide, roles, a teacher script and troubleshooting, it can be run faithfully by any teacher. The traps it pre-empts are the usual ones: a velocity with no direction, dropped units, and averaging two speeds.
