Reflection: Flexibility Determining the Matrix for Transformations - Section 3: Wrap-Up + Homework


I find that my students sometimes struggle with this lesson, so I like to have two closing plans available. My best case plan is that students will work independently beginning on Page 15. I don't always get there.  This year, I ended up just having my kids do a Postcard to Absent Student. I asked them to explain to an absent student how we could determine the matrix to perform a reflection across the y-axis.  

I chose to do this because I could sense frustration building. My students were being challenged enough with learning to determine the matrix. I did not want to waste the last 5 minutes of class by trying to push them too far, too fast.  


  Flexibility: Having a Plan B available helps!

Determining the Matrix for Transformations

Unit 10: Matrices
Lesson 9 of 12

Objective: SWBAT identify the matrix that would perform reflections, rotations, and translations.

Big Idea: Students use manipulatives to discover the matrices that perform various transformations.
