FP1 Unit 3: Numerical Solution of Equations (Edexcel IAL)

A complete, original teaching unit for Unit 3 of the Pearson Edexcel International A Level Further Pure Mathematics 1 (WFM01) specification, following Pearson’s IAL FP1 scheme of work. Two lessons cover locating roots, interval bisection and linear interpolation; and the Newton–Raphson method, including when it fails. Each lesson opens with a starter that checks prior knowledge, then has an editable PowerPoint with worked examples set out as the mark scheme expects, diagrams where they help, practice with answer slides, exam technique, speaker notes and an exit ticket, plus a worksheet with full answers. Also includes a 40-mark unit assessment with a detailed mark scheme and a teacher guide that maps every lesson to real WFM01 past-paper questions from January 2021 to June 2025 (referenced, not reproduced). All PDFs in A4.

Who it’s for: teachers and tutors of students taking Further Pure Mathematics 1 (WFM01) for the Pearson Edexcel International A Level in Further Mathematics. How to use it: teach the lessons in order; set the matching worksheet after each lesson and the 40-mark unit assessment at the end. The teacher guide lists the WFM01 past-paper questions on each topic by session and question number, so students can practise on real exam questions. Mathematical expressions on the slides are high-resolution typeset images (the LaTeX source is in each image’s alt text), while all headings, text boxes, simple expressions in sentences and speaker notes are editable text.
