Lesson 1: Introduction: Scale Drawings
Duration: 50 minutes
Starter Activity (5 minutes)
Quick Recall
3 quick questions to activate prior knowledge about scale drawings. Use mini-whiteboard or paper.
Main Content (35 minutes)
Parent/Teacher Guide: Before lesson: Read script below. Prepare materials. Pre-teach key vocab: R2. If stuck: See Troubleshooting below. Break into smaller steps. Extension: See Stretch & Challenge section.
Teaching Script (35 mins): Mins 0-5 - Hook: "Today: Scale Drawings. Goal: by the end you can a plan scale is 1 : 200. A wall is 6.5 cm on the plan. How long is it really, using the method shown step by step. Connects to units (N13) because you'll reuse its method throughout today's work." Mins 5-15 - Direct Instruction: 1) Define: "Scale Drawings is..." 2) Key principle: "Most important:..." 3) Draw diagram, label live. 4) Real example: "Like A plan scale is 1 : 200. A wall is 6.5 cm on the plan. How long is it really - 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: A plan scale is 1 : 200. A wall is 6.5 cm on the plan. How long is it really?
What is asked? A
Recall knowledge: Real = drawing × scale factor; convert cm → m (÷100) or km (÷100,000); Area scales by the factor SQUARED — a 1 : 100 plan makes areas 1 : 10,000
Apply: 6.5 × 200 = 1300 cm = 13 m
Check: Check the units named in the question and sense-check the size of your answer.
Answer: 13 m
Tip: "Show working - method marks > answer marks."
Worked Example 2: Multi-step
Q: On a map, town B lies on a bearing of 060° from A, 9 cm away. The scale is 1 : 50000. Find the real distance.
Break down: Separate parts?
Solve each: 9 × 50000 = 450,000 cm = 4.5 km, on a bearing of 060°
Combine: The parts chain: each answer feeds the next step of the question.
Final answer: M1 for the scale multiplication, A1 for 4.5 km. Bearings: always three figures, measured clockwise from north.
Worked Example 3: Data/Application
Q: On a map, town B lies on a bearing of 060° from A, 9 cm away. The scale is 1 : 50000. Find the real distance.
Read data: Axes, units, scale
Patterns: Trends, anomalies
Explain: Why? Using scale drawings
Conclude: Evidence-based
Common Questions & Troubleshooting
Q: "Why does Real = drawing × scale factor; convert cm → m (÷100) or km ( work this way?" A: Analogy: "A plan scale is 1 : 200. A wall is 6.5 cm on the plan. How long is it really". 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: "Running out of time." A: 1 mark/min. Skip hard, return. Attempt all - partial marks count.

📝 Mark Scheme Guidance
How examiners mark R2: 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 R2 questions: Underline the command word, count the marks (one mark per point expected), and answer in the format the command word demands.

✏️ 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.
