It's exciting to see a real anti-Daylight Saving Time movement growing! But the real reason to drop it is because it makes no mathematical sense. mrhonner.com/archives/1805 #DaylightSavingTime

Honored to be featured on Sarah’s awesome blog

A couple years ago, a student said "I know it cancels, but I forgot if it cancels to 0 or 1." This is an issue when "cancel" means different things in math. We can say "creates a zero pair" or "simplifies to 1" instead.

Y’all I mostly can’t wait for next school year, but I’m not ready to let go of these work-at-home Wednesdays

ILYSM 💚@desmos 💚

AP Calculus AB/BC rocking the One-Pagers today for various topics of their choosing. Nice job scholars! These are fabulous! #Kirvan #AVIDstrategies OldmillAVID AVIDAACPS

Do your inner mathematician a favor & watch any TikTok from Howie Hua

Getting ready to make a living perpendicular bisector tomorrow do students discover that any point on the perpendicular bisector is equidistant from the endpoint of the segment. Eek! Super excited

Students making discoveries about perpendicular bisectors today in geometry 💙

Geometry students activating prior knowledge #iloveteachinggeometry

I was so glad to share a campsite with y’all

Binge watching You & pretending it’s not Sunday night

Asked students to tell me a joke. Here’s the best one: “When does a joke become a dad joke? When it’s apparent.” #dadjokes

These teachers!! I work with the best people. Can’t wait to see wait the rest of the days of Christmas look like

ShrinkyDinks time!! This is my favorite geometry activity of the year. Love seeing how creative my students are #iloveteachingmath #geometry

Yup! 💯

I don't know who needs to hear this, but like, having the objective on the board doesn't guarantee students are aware of the learning.
