This module covers the evidence skills that sit underneath every Geography topic: choosing a display, reading a photograph, comparing maps, reading proportional symbols and judging a claimed link between two patterns. Check the current Cambridge IGCSE Geography 0460 syllabus page for how the skills are assessed in your exam year.
The data in our examples is invented and labelled as such. The method is what you carry into an unseen question.
What should you already know?
You need basic arithmetic with fractions, percentages and ratios, plus unit conversion between centimetres, metres and kilometres. If scale work feels slow, revise unit conversion first. Everything else is built step by step in the lessons.
One orienting example
An invented map is drawn at 1:50 000, and two villages are 4.2 cm apart on it. The real distance is 4.2 × 50 000 = 210 000 cm. Divide by 100 000 to get kilometres: 2.1 km.
Notice the three habits in that short line: read the scale, convert the unit, then state the answer with its unit. Every lesson in this module trains a similar habit for a different type of evidence.
In what order should you study the lessons?
- Choose a display for a geographic dataset: start here, because choosing the right graph also teaches you to read one.
- Interpret an annotated photograph without inventing unseen features: separates what you can see from what you infer.
- Compare maps with different dates and scales: adds scale arithmetic and fair comparison.
- Read proportional symbols consistently: builds on scale thinking, using area rather than length.
- Identify an unsupported spatial correlation: the most demanding skill, because it needs the other four.
What are the common traps?
- Treating a line graph as suitable for categories that have no order.
- Describing a photograph feature that is not visible in the frame.
- Comparing two maps by centimetres on the page instead of real distances.
- Reading a larger symbol radius as a proportionally larger value.
- Writing “causes” when the data only shows two patterns appearing together.
How should you use the practice set?
Do the mixed practice set after the lessons, not before. Cover each answer, write your own, then compare. Log each miss in the mistake log and retest queue so you can retest it a few days later.
The map scale, contour and gradient practice tool and the statistics and distribution explorer give extra repetitions. When you want someone to watch your reasoning on unseen material, see our online one-to-one Geography tuition.
