SWBAT understand rotations about the origin.

Set the foundation for students' understanding of rotations about the origin - link it to tether ball!

Each day, students complete a warm-up that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

I like reviewing the GOLD question for the huddle for this lesson, since it pushes kids to rotate a single point, allowing them to see the pattern that emerges for any incremental 90-degree rotation.

I tell the kids that I do NOT expect them to memorize these rules, but to apply them by sketching their own visuals and then applying systematic, logical thinking. I love the kind of thinking process this pushes.

Homework is to be completed at home and should take the student approximately 15 minutes.
