This 3-week module is based on Montana’s Content Standards for 8th grade geometry with a focus on transformations (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. Specific goals and activities include the following:

• Identify and analyze common misconceptions in students’ understanding of transformations.
• Investigate model lessons dealing with important concepts related to rigid transformations and congruence versus similarity.
• Explore how to support students’ use of the Mathematical Practices through informal geometric proof and modeling.
