ENROLLMENT OPENS Mar. 15, 2020 – STREAM: Exploring Transformations 7-9 (Apr. 5-25, 2020)

This 3-week module is based on Montana’s Content Standards for 8th-grade geometry with a focus on translations, rotations, reflections, and dilations. We will examine students’ perceptions about transformations, explore and justify relationships between figures, and discover geometric connections to similarity, proportion, and slope.

ENROLLMENT OPENS Dec. 15, 2019 – STREAM: Transformations and Proofs HS (Jan. 5-25, 2020)

The introduction of the Common Core standards inspired a change in the mindset of “basing transformations on congruence” to the more intuitive approach of “basing congruence on transformations.” In modern geometry, the traditional arguments justifying congruence and similarity are more effectively supported by rigid transformations and dilations. In this 3-week module, we examine how transformations are applied to justify congruence and similarity.
