This lesson breaks down how the theorem was formed, giving students an opportunity to truly understand the concept before they apply algebraic reasoning. With the google add-on Peardeck, students can interact directly with the lesson from their computer. You, as the teacher, can see all student answers and share your favorite responses with the class!

What is Pear Deck?

Pear Deck is a google add-on that allows you to create an interactive assignment for your students. Pear Deck is great for teachers because as the teacher you are able to see each student or group's response on your personal device. This gives you an opportunity for immediate intervention and reteach. If you are not on a 1 to 1 campus you can use this formative assessment as a center or have students work in groups taking turns answering the questions.

**This product does not need to be used with Pear Deck. You can also project the presentation and use it as a guided review or starter.
