Scaling Cubes
Source Institutions
In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.
