Seventh graders learn how scale drawings — maps, blueprints, and models — use a scale to shrink or enlarge real objects proportionally, and how to convert between drawing measurements and real ones.
Students will be able to…
A map fits a whole city on one page, and a blueprint shrinks a house to fit on paper. How does a scale let a drawing represent something much bigger — accurately?
Project each item and have students use the scale to find the real (or drawing) measurement. The tool explains scale factors.
