IGCSE Physics: Calculating Speed | Edexcel Modular | Unit 1 | L1

This lesson covers spec point 1.4 — knowing and using the relationship between average speed, distance moved and time taken.

PowerPoint includes:
• Retrieval starter reviewing SI units for distance, time and speed
• Direct Instruction (I Do) — average speed equation introduced (v = d ÷ t) in words and symbols; each variable defined with units; worked examples calculating speed, distance and time with full substitution shown
• Guided Practice (We Do) — three calculations: calculate speed from distance and time; calculate distance from speed and time; calculate time taken for a given journey
• Independent Practice (You Do) — real-world speed calculations (cars, cyclists, sprinters); rearrangement tasks; multi-step problems
• Review and Reflect — 3 MCQs and exit ticket calculation

Activity Sheet includes:
• Formula box: v = d / t
• 10 exam-style questions covering speed, distance and time calculations, rearrangements and real-world contexts
• Stretch question requiring multi-step reasoning to compare two journeys
• Full mark scheme for teacher use
