Today we are launching into the #Math behind #fireworks for #July4th. #Quadratic #equations keep people safe, launching the firework at the correct angle & trajectory. (See yesterday’s post for #Chemistry and tomorrow’s for #Physics.) bit.ly/2IPH4OK

@askmrsmartinez SD Math Network Melisa O'Donoghue So glad you were a part of it-not only coming to PD events but promoting and facilitating too! We gotta brainstorm ways to keep it going...

The #1 recommendation from NCTM for catalyzing change in high school mathematics is to eliminate student and teacher tracking. Why the recommendation? “High School Mathematics is Not Working.”-NCTM #nctmannual

@askmrsmartinez Melisa O'Donoghue SD Math Network The math events are great because of the great teachers that show up! Thanks for always being so supportive and so fun to work with, Aly!
