Just as rigid motions are used to define congruence in Module 1, so dilations are added to define similarity in Module 2.

Module 3, Extending to Three Dimensions, builds on student's understanding of congruence in Module 1 and similarity in Module 2 to prove volume formulas for solids.

Using the Virginia Museum of Fine Arts website, students explore the sculptural work of 20th Century Conceptual artist Sol LeWitt to expand their understanding of geometric concepts, creatively play with mathematical ideas, and be inspired to make art of their own.

The website page provides a scaffolded approach to exploring Sol LeWitt's sculpture titled "1, 2, 3, 4, 5, 6." culminating in a challenge for students to build a 3-D Tinkercad model of a geometry concept of their own choosing.

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. Learners build bigger and bigger cubes to understand these scaling relationships.
