It was fun to see the different designs they came up with. They seemed very engaged!

My smart board pens wrote in the correct colors today for the first time in months without randomly changing colors. This was my excitement for today! It's the little things sometimes...

My students had fun tossing tennis balls and using the Motion Shot app to model projectile motion with quadratic functions on @Desmos! #MTBoS #iteachmath #iteachalg2 #quadraticmodeling
