Overview

A complete GCSE Mathematics teaching and revision bundle for averages, range, grouped data and sampling. This resource supports students in calculating and interpreting mean, median, mode and range, then extends into frequency tables, stem-and-leaf diagrams, grouped data estimates and sampling methods.

The pack is designed to help learners build fluency while understanding what each statistic means in context. Clear notes, fully worked examples, progressive practice, challenge tasks and a mini assessment make the topic suitable for classroom teaching, homework, revision and cover lessons.

Teacher-facing files are included to support planning, explanation, questioning, differentiation and misconception handling, so the full bundle can be used confidently across a GCSE Mathematics sequence.

What’s Included

This bundle includes:

• Presentation Slides —
• Student Notes — clear explanations, key vocabulary, worked mini-examples, common mistakes, quick checks and summary notes.
• Worked Examples — fully solved GCSE-style examples covering lists, frequency tables, comparisons, stem-and-leaf diagrams, outliers, grouped data and sampling.
• Practice Questions — progressive questions from core fluency to mixed application, with marks shown for each question.
• Challenge Questions — harder problem-solving tasks involving reverse mean, comparisons, outliers, grouped estimates and stratified sampling.
• Mini Assessment — a 45-mark assessment for checking understanding across the whole topic.
• Mark Scheme — detailed answers with method guidance, mark allocations, acceptable alternatives and common errors.
• Lesson Plan — a structured teaching sequence with starters, lesson flow, checks for understanding, differentiation and homework guidance.
• Teaching Notes — teacher explanations, misconception interventions, mini-whiteboard checks, questioning prompts and plenary ideas.
