Overview

A complete teaching and revision bundle for Algorithms on Graphs in Pearson Edexcel International A Level Decision Mathematics 1. This resource supports the core graph algorithms students need for minimum spanning trees, matrix methods, nearest-neighbour routes and Dijkstra shortest paths.

The materials are designed to help students learn each algorithm step by step, practise clear written working, understand common modelling distinctions and prepare for assessment-style questions. The complete bundle also includes classroom presentation slides as a core teaching tool for whole-class delivery.

Teachers can use the pack for direct instruction, guided practice, homework, intervention, revision or assessment preparation. The presentation slides provide a premium classroom-ready lesson sequence with visual explanations, worked examples, guided practice, misconception checks and plenary material.

What’s Included

This bundle includes:

• Student Notes — clear explanations, method boxes, vocabulary, worked mini-examples, common mistakes and quick checks.
• Worked Examples — fully solved examples for Kruskal’s algorithm, Prim’s algorithm, matrix Prim, nearest neighbour and Dijkstra’s algorithm.
• Practice Questions — progressive questions covering routine and standard applications with clear mark values.
• Challenge Questions — higher-demand tasks involving ties, non-unique solutions, interpretation and error analysis.
• Mini Assessment — a timed assessment-style check covering the main chapter skills.
• Mark Scheme — detailed solutions with method marks, accuracy marks, acceptable alternatives and common errors.
• Lesson Plan — a structured teaching sequence with starter, main activities, checks for understanding, differentiation and homework suggestions.
• Teaching Notes — teacher guidance, questioning prompts, misconception interventions, mini-whiteboard checks and delivery support.
• Presentation Slides — a premium classroom-ready slide deck for whole-class teaching, worked examples, guided practice, misconception checks, visual explanations and lesson delivery.
