OCR A-level Maths: Exponentials and Logarithms (Pure Year 1) – Complete Lesson Pack

A complete, ready-to-teach OCR A-level Maths (H240) lesson on exponentials and logarithms, for Pure Year 1. Students meet exponential graphs and eˣ, treat logs as the inverse of powers, use the log laws to solve equations, and apply exponential models and log graphs to real data. Built for teachers and tutors who want fully modelled lessons without hours of preparation. Covers OCR specification 1.06a, 1.06c, 1.06f, 1.06g, 1.06h, 1.06i.
Topics covered:
• Sketch y = aˣ and y = eˣ, and know that d/dx(eᵏˣ) = keᵏˣ
• Understand logarithms as inverses of exponentials, and use the laws of logarithms
• Solve equations of the form aˣ = b, and equations involving logs, e and ln
• Use exponential models, and logarithms to turn curves into straight lines
What’s included: annotated PowerPoint with click-by-click I do / We do modelling and speaker notes (plus a PDF); Bronze, Silver and Gold exam-style worksheet with full worked answers; two A5 student help cards; a two-page teacher guide with OCR spec links, timings and misconceptions; double-sided homework (21 questions, 47 marks: AO1 23, AO2 12, AO3 12) with a separate answer copy; printable exit tickets.
