SI Unit Conversion and Using Scale – Activity and Project
The first activity aims to practice using a scale on a map and converting metric (SI) units.
Students use rulers to measure a distance on the map in centimeters, then use the scale on the map to find the true distance (in cm), and finally convert the measurement to kilometers.
The second activity/project challenges students to build a model of a house. Students choose one of 3 options (each with 4 dimensions of a basic house) and create a scale. The scale is used then to size down the house and create the model out of cardboard or construction paper. This project takes approximately 3-4 class periods to complete; students often struggle with initial calculations and determining a workable scale but with practice become much more comfortable with the process.
