Activity 01
Scale Challenge: Measuring Routes
Provide maps of Ontario regions at different scales. Pairs select a route, measure it on the map using rulers, convert to real distances with scale bars, and compare results. Discuss discrepancies and refine calculations as a class.
Analyze how different map scales affect the level of detail presented.
Facilitation TipDuring Scale Challenge, have students work in pairs with real rulers and string to measure distances on a school campus map, forcing them to confront measurement errors and scale inconsistencies directly.
What to look forProvide students with a small topographic map section. Ask them to: 1. Identify the map scale and calculate the real-world distance between two marked points. 2. List three symbols from the legend and explain what they represent.
