My new math crush!

Love it!

Your students are ready for this. #iteachmath #MTBos

A little something to satisfy your #fractional thinking #iteachmath #MTBos

Stop planning! Here’s your math task for tomorrow #iteachmath #mtbos #persevere

Tell me what’s wrong with this question…

Sunday #puzzle What fraction of the black equilateral triangle is shaded in red ? #GeometrySnacks #WFIS @edsouthall

I need 153 followers to break 75k so why not give back to a lucky classroom (and it’s my birthday week!) I’ll donate $153 to a random teacher who retweets this if I break 75k followers by midnight. #LetsDoThis #ClearTheList #TeacherTwitter #CodeBreaker

Big news: Polypad now supports 3D geometry! 🎉⚽️🎁 Use one of our built-in solids, or create your own net using polygon tiles. Then click “fold” and watch the magic happen…

Made some fraction addition and subtraction repeated practice with visual feedback in @desmos. #iteachmath #mtbos teacher.desmos.com/activitybuilde…

Thinking about restarting #ObserveMe. Is anyone still doing that with their classrooms?
