Another triangle and circles phenomenon geogebra.org/m/q7Kv4fyf GeoGebra Antonio Gutierrez #MTBoS #ITeachMath #geometry

Start of today’s #ThinSlice in one of our #ThinkingClassrooms. When Ss analyze and discuss with each other on their feet, initial learning is SO MUCH BETTER. Engineering & Science University Magnet School Peter Liljedahl #BTCthinks

Interesting rhombus surprise! 👀 geogebra.org/m/pheqetJQ GeoGebra Antonio Gutierrez #MTBoS #ITeachMath

Another right triangle wonder. How can we prove this phenomenon true? 🤔 geogebra.org/m/vjkqPrEr GeoGebra Antonio Gutierrez #MTBoS #ITeachMath

Using technology to explore in a thinking classroom. I love it when Ss actively engage with mathematics, regardless of the simplicity or complexity of what it is I want them to discover. (Here, a very simple concept.) geogebra.org/m/myqhscbz Peter Liljedahl Engineering & Science University Magnet School GeoGebra

Lots of crazy phenomena happen when you build equilateral triangles off the sides of any ordinary triangle. Check this out! 👇 geogebra.org/m/MzZ97W9U GeoGebra Antonio Gutierrez #MTBoS #ITeachMath #geometry

Here, Peter Liljedahl virtually kicking off the start of the #acespdsi CT Building Thinking Classrooms Conference. 200 people from all over CT here today.

.Melisa McCain : It wasn’t the same presenting without you! But nonetheless, I’m glad our session still rocks the boat (in a good way) and gets people talking about how we need to change how we grade. 🙂 Here, at a BTC CT conference hosted by ACES. #acespdsi Peter Liljedahl

Square & quarter-circle wonder. But why? 🤔 geogebra.org/m/HWc2dVtF GeoGebra Antonio Gutierrez #MTBoS #ITeachMath #geometry

My first T job started JAN 2, 2002 and went to June 02. And all these years later I run into Lara B., the T who I temporarily replaced as a long-term sub when she went on maternity leave back then. Ironically, her Dad was my Calc 1 prof. Central Connecticut State University back in Fall 97 #DejaVu

Really enjoying listening to this discussion among Sunil Singh , Steve Phelps, Bobson Wong , & Desiree Y. Harrison . Is NCTM worth it?
