Lesson 1: Introduction: Multiplicative Relationships

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

3 quick questions to activate prior knowledge about multiplicative relationships. Use mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read script below. Prepare materials. Pre-teach key vocab: R6.
If stuck: See Troubleshooting below. Break into smaller steps.
Extension: See Stretch & Challenge section.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: Multiplicative Relationships. Goal: by the end you can 3 tins cost £2.10. How much do 7 tins cost, using the method shown step by step. Connects to proportion (R7/R10) because you'll reuse its method throughout today's work."
Mins 5-15 - Direct Instruction: 1) Define: "Multiplicative Relationships is..." 2) Key principle: "Most important:..." 3) Draw diagram, label live. 4) Real example: "Like 3 tins cost £2.10. How much do 7 tins cost - the same maths you already do when shopping or cooking..."
Mins 15-25 - Guided Practice: Ex1: Teacher models. Ex2: Student tries with guidance. Ex3: Student independent.
Mins 25-35 - Independent Practice: 3-5 questions. Immediate feedback.
Worked Example 1: Basic

Q: 3 tins cost £2.10. How much do 7 tins cost?

  1. What is asked? 3
  2. Recall knowledge: Multiplier = new ÷ old — apply the SAME multiplier to every connected quantity; Inverse multiplier: to reverse a ×2.5, use ÷2.5 (or ×2/5)
  3. Apply: Multiplier 3 → 7: 7/3 · £2.10 × 7/3 = £2.10 ÷ 3 × 7 = £4.90
  4. Check: Check the units named in the question and sense-check the size of your answer.
  5. Answer: £4.90

Tip: "Show working - method marks > answer marks."

Worked Example 2: Multi-step

Q: A map has scale 1 : 50000. How many km does 4 cm represent?

  1. Break down: Separate parts?
  2. Solve each: 4 × 50000 = 200,000 cm = 2 km
  3. Combine: The parts chain: each answer feeds the next step of the question.
  4. Final answer: M1 for × 50000, A1 for 2 km (the cm → km conversion is part of the mark).
Worked Example 3: Data/Application

Q: A map has scale 1 : 50000. How many km does 4 cm represent?

  1. Read data: Axes, units, scale
  2. Patterns: Trends, anomalies
  3. Explain: Why? Using multiplicative relationships
  4. Conclude: Evidence-based

Common Questions & Troubleshooting

Q: "Why does Multiplier = new ÷ old — apply the SAME multiplier to every work this way?"
A: Analogy: "3 tins cost £2.10. How much do 7 tins cost". Try re-draw the worked example from memory, then check it against the model answer.
Q: "Wrong answers on calculations."
A: Checklist: units? formula? calculator mode? sig figs?
Q: "Can't remember key terms."
A: Flashcards (term front, def+diagram back). Spaced repetition: day 1, 3, 7.
Q: "Exam wording confuses me."
A: Commands: Describe=what you see; Explain=reasons; Evaluate=pros/cons+judgement; Calculate=working+units.
Q: "Running out of time."
A: 1 mark/min. Skip hard, return. Attempt all - partial marks count.

Assessment Criteria

📝 Mark Scheme Guidance

How examiners mark R6: Read the command word carefully — State = one word/phrase (1 mark), Describe = pattern or detail (2 marks), Explain = reason with "because" (2–3 marks), Compare = similarities AND differences, Evaluate = both sides + conclusion. Method marks are awarded for correct working even if the final answer is wrong. Always show your working — unexplained answers score zero for AO2.

Success on R6 questions: Underline the command word, count the marks (one mark per point expected), and answer in the format the command word demands.

Board Notes & Revision Links

This lesson is examined by: AQA 8300 | Edexcel 1MA1 | OCR J560 | Eduqas C300 | CCEA M-units. Tier and paper details vary - always check your board's current specification.

Follow-up revision: R6-multiplicative-relationships on GCSE Revise (notes, flashcards and auto-graded target tests for this exact topic).

📐 Reference Diagram

3 parts (£30) 5 parts (£50) Total: 8 parts = £80 → 1 part = £10 Ratio 3 : 5 → Amy gets £30, Ben gets £50

✏️ Draw-Along Instructions

Parent/teacher: Draw a bar divided into parts proportional to the ratio. Label each part with its value. Write the total above. The ratio tells you how many parts each person gets.

Display the reference diagram (or draw it live) while pupils copy. Check each label as it is added.
