@NorthPortPolice Does he have the white van?

KNow anything? Please call 1-800-CALL-FBI

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

I put together a new activity, "Watering the Lawn", a real-life application of graphing circles. Check it out and let me know what you think! #iteachmath #mtbos #graphingcircles #reallifemath #iteachprecal @Desmos teacher.desmos.com/activitybuilde… docs.google.com/document/d/182…

Any good PiDay activities for the high school PreCal or Alg2 classroom??? Something that doesn't involve food... #PiDay #iteachmath #mtbos #iteachprecal #iteachalgebra2

@JacquiLehmkuhl Do you have these yet?!?! #iteachmath #MTBoS #backtoschoolshoes #toms

@Mathkies @MrHadzovic @ddmeyer Yes this has been a game changer!

@MrHadzovic @ddmeyer Also adding teachers of like courses as collaborators to classroom. Then you can repost each other’s posts as well.

Teacher in the Desmos FB group says: "It takes a heck of a lot more time and energy to prepare lessons to do online versus teaching in class." Has that been your experience? Any time-saving tips to share?

Here is a website with awesome resources if you a switching to online learning. Lots of Desmos activities! #desmos #iteachmath #MTBoS martycmath.weebly.com/desmos.html

@kim_yoak I sure hope so.

@MrsArnoldPlus1 I did this too. You could also have piecewise discussion. There seems to be 2 pieces if you go back to Jan 23. desmos.com/calculator/xhx…

Yep, I went there today. Look how well this curve fits the data!! The x=0 is February 26th and the y-values are the confirmed U.S. COVID-19 cases each day since. Guess how many a week from today?? #coronavirus #iteachmath

@zimmerdiamonds @gogogoggin 11th grade Algebra 2

Have students calculate a motorcycle's speed using the same method used by police for writing the speeding ticket. Lesson here: bit.ly/2bYjrnI #MTBoS

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...

So much math in this awesome video (including a quick @ddmeyer @Desmos cameo)! @MarkRober #quadraticmodeling #iteachmath #MTBoS youtube.com/watch?v=MHTizZ…

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 teacher.desmos.com/activitybuilde…
