- Module 3 Pre-Prerequisite Assessment
- Covers 6th and 7th grade ratios and proportional relationship standards
- Module 3 covers dilations—foundational learning came in 7th grade with scale drawings.
- Module 2 Assessment Review
- Brief review assessment to see where students are at from the previously taught module—need to identify gaps

Wednesday / 8.G.A.4
Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them. / TSW…
Investigate the properties of dilations. / MP.3 Construct viable arguments
MP.8 Repeated reasoning. /
- Dilation Investigation
- For this activity, students create their own design on a coordinate plane and use this design to explore properties of dilations. They will be asked to shrink and expand their design by a given scale factor, compare the coordinates of each design, and finally be given an opportunity to prove the properties of similarity and dilation on a coordinate plane. Students will use a protractor to demonstrate corresponding angles are equal.

Thursday / 8.G.A.4
Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. / TSW…
Take a pre-requisite assessment for module 2. / MP.3 Construct viable arguments
MP.8 Repeated reasoning. / Module 3~Lesson 3: Examples of Dilations
- Example 1:
- Ask students to (1) describe how they would plan to dilate a circle and (2) conjecture about what the result is when they dilate a circle.
- Exercises 1-2:
- Students dilate an ellipse on the coordinate plane.
- Example 2-3: Mapping figures BACK to their original figure
- Exercise 3:
- Describe sequences that map one figure onto another
- Closing:
- What were the main points of this lesson?

Experimentally verify the properties related to the fundamental theorem of similarity (FTS). / MP.3 Construct viable arguments
MP.8 Repeated reasoning. / Module 3~Lesson 4: Fundamental Theorem of Similarity (FTS)
- Opening Exercise: Learn Zillion task
- Discuss Theorem
- Exercise: Students use the FTS theorem to answer questions given a dilation.
