In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.
