Study guide: A Map Answers Some Questions
Use scales, grids, route sums, and dated notices to interpret map evidence.
Ideas to explain in your own words
- Convert equal map segments into fictional ground distances.
- Use a stated column-row convention to locate a fictional map feature.
- Calculate and compare complete fictional route lengths.
- Separate location evidence from a later closure report.
Watch your reasoning
- There are three segments, each representing 200 meters. 200 + 200 + 200 = 600 meters. This calculates the shown route, not an unshown shortcut.
- A3 is explicitly assigned to the tower. A1 is the hall, so the row number matters.
- Six minus four is two extra segments; 2 × 150 = 300 meters. Equivalently, 900 − 600 = 300 meters.
- May 5 falls within May 4–6, and the notice names only pond–garden. It does not describe the other listed connections.
A worked review example
Use a Map’s Distance Rule: Two 200-meter segments total 200 + 200 = 400 meters. The number of segments and the scale rule are both needed. Locate a Feature in a Grid: “The garden is at B2. The pond at C3 is one column east and one row north of it, so the pond is northeast of the garden on this supplied grid. The grid supplies no distances.” Compare Two Shown Routes: “Route A: 4 × 150 = 600 m. Route B: 6 × 150 = 900 m. B is 300 m longer; A is shorter among these two shown routes. The map does not establish opening hours.” Read a Map’s Date and Purpose: “On May 5, gate–pond–garden uses a connection reported closed. Gate–hall–garden uses shown connections not reported closed by this notice. That is a paper-map conclusion, not a guarantee about real travel.”
Make a practice plan
- Try the supplied lesson problems without looking at the answers.
- Compare your method with the worked examples and explain any correction.
- Use the new review cases, then complete the transfer task on paper or in your own document.
