Discussing Math

During this semester, I would like us to start talking and providing evidence for the results we get. Just as we did in ADL, I always asked you to provide evidence in proof of your answers. I want each and everyone of you to have a deeper understanding of Math. I don't want you to simply memorize the formulas and/or methods used to solve mathematical problems. 

The chart paper above is displayed in my new room, 403, I would like us to get in the habit of using these sentence starters to express your knowledge and operations used in Math. 

Math isn't just about numbers!
