They say friends are family you choose for yourself. Grateful @stephenjull and I were finally able to catch up this time NOT in front of a screen. 🙂 (Last time we hung out was ISTE18 in Chicago). #ISTELive

Secretly embedded inside every square is a 3-4-5 right triangle! 😮 How can we formally prove this phenomenon true? 🤔 Source: @gogeometry geogebra.org/m/dMNUJHTa @geogebra #MTBoS #ITeachMath #geometry #math #MathChat

Absolutely ❤️ how @GraspableMath helped my Ss actively wrestle and make sense of their algebraic misconceptions in their setups re: Law of Sines. With GM activities, you can disable drag feature (across = sign) so Ss need to indicate what to do to both sides of any equation!

Requests please! We've just started building a few auto-assessed GM 'worksheets' tagged with common core standards. activities.graspablemath.com… We're making a few more...and thought we'd ask our teaching friends: are there any specific topics coming up that you'd like us to cover?

My week has been transformed after @LeadbeaterCh switched me onto the amazing @SAFE_Project where you can listen in real time to the sounds of the Borneo rainforest courtesy of their @Raspberry_Pi powered acoustic monitoring system. acoustics.safeproject.net/21…
