Students will watch an instructional math video in which the math teacher provides detailed instruction that goes along with the Student Handout. Students will take notes and be guided through multiple examples. There are practice problems (or "You Try") sections where students can practice problems that correspond to content examples covered in the videos. There are no videos for the practice problems; rather, the solutions are provided in the Teacher Guide. Stop and start the video as needed!
Students will need Internet access, a writing utensil, a calculator (TI 84 is used in the videos), and a copy of the Student Handout.
In the Facilitator Guide, you will find specific instructions for using the materials.

Additional Resources:
Transformations | (videos and practice) | Khan Academy - Learn about the most useful math concept for creating video game graphics: geometric transformations, specifically translations, rotations, reflections, and dilations. You will learn how to perform the transformations, and how to map one figure into another using these transformations.
Intro to Triangle Similarity | (video) | Khan Academy - Sal explains what it means for triangles to be similar, and how this follows from the definition of similarity.
