Unit 4: Measurement, Scale, and Precision
Duration of Days: 10
How to use an Architect’s and Engineer’s scale, the math behind "Grid Scaling," and why scale is critical for manufacturing and construction.
Re-draw objects at 1:2, 2:1, and 1:4 scales using the grid method; practice hand-scaling physical objects using calipers or rulers.
A "Scale Accuracy Lab" where students must measure a physical classroom object and produce a perfectly scaled hand-drawing of it
