4 detailed 50-minute lessons with teaching scripts, worked examples, parent guides, and assessment criteria.

Write down everything you already know about cartographic skills. Then check against the key terms: Exam Tip, Rule, Rule. Use a mini-whiteboard or paper.
Start with the revision notes summary, then attempt: Explain how to give a 6-figure grid reference.
Your student states one thing they learned and one question they still have about cartographic skills.
Quick recap: write 3 key points from Lesson 1 on cartographic skills. Check them against the notes below.
| Term | Meaning | Example |
|---|---|---|
| 1:25,000 | 250 m | OS Explorer; walking; fieldwork; exam extracts |
| 1:50,000 | 500 m | OS Landranger; route planning; regional studies |
| 1:250,000 | 2.5 km | Regional road maps; atlas maps |
| Steep slope | Contour lines close together | Height increases rapidly over a short horizontal distance |
| Gentle slope | Contour lines far apart | Height increases gradually over a longer distance |
| Valley / V-shape | V-shaped contour lines pointing uphill (towards higher ground) | A river or stream flows along the valley floor; the V points to the source |
| Spur / Ridge | U-shaped contour lines pointing downhill (towards lower ground) | A finger of higher ground projecting from a hill; the U points to the lower end |
| Summit | Concentric rings getting smaller towards the centre | The highest point; often marked with a spot height or trig point |
Q: Explain how to give a 6-figure grid reference.
Answer: To give a 6-figure grid reference: (1) Identify the 1 km square the feature is in; (2) Read the easting (bottom-left number along the bottom); (3) Estimate how many tenths across the feature is from the left edge of the square (0-9) and insert as the 3rd digit; (4) Read the northing (bottom-left number up the side); (5) Estimate how many tenths up the feature is from the bottom edge (0-9) and insert as the 6th digit. Example: a feature 4 tenths across and 8 tenths up in square 4728 has the reference 474288.

Q1: Explain how to give a 6-figure grid reference.
Answer: To give a 6-figure grid reference: (1) Identify the 1 km square the feature is in; (2) Read the easting (bottom-left number along the bottom); (3) Estimate how many tenths across the feature is from the left edge of the square (0-9) and insert as the 3rd digit; (4) Read the northing (bottom-left number up the side); (5) Estimate how many tenths up the feature is from the bottom edge (0-9) and insert as the 6th digit. Example: a feature 4 tenths across and 8 tenths up in square 4728 has the reference 474288.
Q2: On a 1:25,000 OS map, two points are 7.2 cm apart. What is the actual distance between them in kilometres?
Answer: Actual distance = map distance × scale = 7.2 cm × 25,000 = 180,000 cm = 1,800 m = 1.8 km.
Q3: Describe the contour pattern you would expect to see for (a) a steep slope, (b) a valley, (c) a summit.
Answer: (a) Steep slope: contour lines very close together, indicating height increases rapidly over a short distance. (b) Valley: V-shaped contour lines pointing uphill (towards higher ground), with the river flowing along the valley floor away from the point of the V. (c) Summit: concentric rings of contour lines getting smaller towards the centre, with the highest point in the middle, often marked with a spot height or trig point symbol.
Q4: A river drops 150 metres over a horizontal distance of 3 km. Calculate the gradient as a ratio.
Answer: Gradient = VI ÷ HE = 150 m ÷ 3,000 m = 150/3000 = 1/20 or 1:20. This means for every 20 metres horizontally, the land rises 1 metre vertically.
Q5: Explain what vertical exaggeration is and why it is used in cross-sections.
Answer: Vertical exaggeration is when the vertical scale of a cross-section is larger (shows more detail) than the horizontal scale, making slopes appear steeper than they really are. It is used because real landscapes often have gentle slopes that would appear almost flat if drawn at true scale. For example, if horizontal scale is 1:25,000 and vertical scale is 1:5,000, the vertical exaggeration is 5x. Always state the vertical exaggeration so the reader knows slopes appear steeper than reality.
Q6: What is a bearing and how is it different from a compass direction?
Answer: A bearing is a precise angle measured clockwise from north (0-360°), expressed as a 3-digit number (e.g. 045°, 270°). A compass direction is an approximate direction using cardinal and intercardinal points (N, NE, E, etc.). A bearing is more precise - "NE" could mean anything from 022° to 068°, while a bearing of 045° is exact.
Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.
Review what these command words require: state (one point), describe (say what happens), explain (say why), compare (both sides), evaluate (judgement).
Attempt a past-paper style question on cartographic skills from the exam board past paper finder (see Resources), then mark it against the scheme.

Tick each item honestly — if any box is unticked, re-read the relevant section above.
How examiners mark cartographic skills - GCSE Geography Lessons: 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 cartographic skills - GCSE Geography Lessons questions: Underline the command word, count the marks (one mark per point expected), and answer in the format the command word demands.
