Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: s2 charts diagrams. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Statistics because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.

|---|---|
| Bar Chart | Comparing discrete categories |
| Pie Chart | Showing proportions of a whole |
| Pictogram | Simple data for younger audiences |
| Vertical Line Chart | Discrete data with frequency |
| Time Series | Data changes over time |
| Frequency Table | Organising data by categories |

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.
Q1: Calculate the angle for a pie chart sector representing 15 students out of a total of 60.
Answer: (15/60) × 360° = 90°
Q2: A pictogram uses ⭐ = 6 points. How many stars are needed to represent 27 points?
Answer: 27 ÷ 6 = 4.5 stars (4 full stars and 1 half star)
Q3: In a bar chart, what should be the height of the "Blue" bar if 24 people chose blue out of 120 surveyed?
Answer: Height = 24 (the frequency value)
Q4: A pie chart has a sector of 90°. If the total frequency is 200, how many does this sector represent?
Answer: (90/360) × 200 = 50
Q5: Describe the trend shown in a time series graph where values go: 8, 7, 6, 5, 4, 3 over six months.
Answer: Downward trend (decreasing) - values are falling from 8 to 3 over the six months.

Extended Answer
Extended question: Extended Answer 6 marks: The table shows monthly sales for a shop over two years: Month Jan Feb Mar Apr May Jun 2024 12 14 18 22 26 30 2025 15 17 21 25 29 33 (a) Draw a time series graph showing both years. (b) Describe the trend and compare 2024 with 2025. (c) Estimate sales for August 2025, giving a reason for your estimate. <div class="
(a) Plot both years on the same axes with months on x-axis and sales (£000s) on y-axis. Connect points within each year. Use different colours or a key for 2024 and 2025. (b) Both years show an upward trend (increasing sales from January to June). 2025 sales are consistently higher than 2024 by approximately £3000 each month. The rate of increase is similar in both years. (c) The monthly increase is roughly £4000/month. By August (2 months after June): 33 + 4 + 4 = £41,000. Alternatively, the pattern from 2024 shows growth slows in later months, so a lower estimate of £38,000 may be more realistic. Mark scheme: M1 for plotting points, A1 for connected time series with key, M1 for describing upward trend, A1 for comparing years, M1 for extrapolation with reason, A1 for reasonable estimate with justification
Exam Tips: Always label axes and include a title | Check pie chart angles add up to 360° | Include a key for pictograms | For bar charts, ensure bars have equal width with gaps | Look for trends and patterns in time series | Read the scale carefully - don't assume it starts at 0
Common Errors: Watch Out! 1. Wrong: In a pie chart, using the frequency as the angle (e.g. drawing 80° for Pizza because the frequency is 80) Correct: Angle = (frequency/total) × 360° — the angle depends on the proportion, not the raw frequency 2. Wrong: Drawing a bar chart with no gaps between bars (that's a histogram for continuous data) Correct: Bar charts have gaps between bars because the data is discrete/categorical 3. Wrong: Reading a chart value by reading the wrong axis or misreading the scale (e.g. each square = 2, not 1) Correct: Always check the scale divisions before reading values — count the squares and work out what each one represents
AO3 - Reasoning & Interpretation: Reasoning and Interpretation A pie chart shows how a school budget of £500,000 is spent: Salaries 210°, Resources 72°, Maintenance 54°, Other 24°. (a) Calculate the amount spent on Salaries. (b) What fraction of the budget is spent on Resources? (c) The headteacher says "We spend more on Salaries than everything else combined." Is this correct? Show working. Answers: (a) Salaries: (210/360) × £500,000 = £291,667 (b) Resources: 72/360 = 1/5 of the budget (c) Salaries = 210°. Everything else = 72+54+24 = 150°. Since 210° > 150°, the headteacher is correct — Salaries take up more than half the budget.
