Lesson Plan: Scale Drawings and Models
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the scale factor and the dimensions of both the scaled model and the actual object and apply this to real-world problems.
Objectives
Students will be able to
- understand the relationship between the drawing scale, the actual length, and the drawing length,
- calculate the drawing scale, the actual length, and the drawing length,
- define minimization and enlargement and their relation to the drawing scale,
- decide whether a drawing scale represents a minimization or an enlargement.
Prerequisites
Students should already be familiar with
- ratio notation,
- ratio as fractions,
- proportion,
- unit conversion.
Exclusions
Students will not cover
- scales other than and .
