Mrs. Polinski set a great tone for the year by having students complete the 100 Numbers task in groups, write individual reflections on what group work looks and sounds like in math, and share out in small and whole groups on the first day of class! Heritage High School @LCPS_Math #MTBoS

So glad I had the opportunity to join one of Becky Ring's classes for a data talk from the The New York Times, and another class for a powerful reflection activity! Loudoun Valley HS @LCPS_Math #MTBoS #ITeachMath

Mrs. Andrea got her students communicating at the beginning of class with a slow reveal graph (slowrevealgraphs.com), and they later engaged in a collaborative learning station! Loudoun Valley HS @LCPS_Math #MTBoS #ITeachMath

Mr. Powers fosters international mindedness with his intro to the squeeze theorem! He shared the French (Théorème des gendarmes) and Russian names and some of the history behind it. His accompanying graphic also helped the theorem stick with his Ss! Loudoun Valley HS @LCPS_Math

Ss in Rodney Snyder's class have been learning to count... in other bases! One S shared a magic trick based on 😉 base 2. Turns out there was a "bug" in the trick, which sparked a great discussion about how much we learn from mistakes and de-bugging code! Loudoun Valley HS @LCPS_Math

PEMDAS is trending again so I'm begging you to just use clearer notation

A thought-provoking read: To Address Learning Gaps, Go Deeper ascd.org/el/articles/to… via ASCD

Today a student in Cheryl Helbing's Geometry class asked why there are 360 degrees in a circle - a great question and I didn't know the answer! A quick Google search yielded a lot of interesting information but no definitive answer! Heritage High School @LCPS_Math #mtbos #iteachmath

Happy NCTM Day! Thrilled to be here with so many @LCPS_Math teachers!!! #NCTMDC23

Next: “Centering Students as the Facilitators of Discourse” with @annmgaffney and Anna Roberds. How we as teachers can give students the space to generate thoughtful questions because we learn mathematics through TALKING about it! Great new task idea, too! NCTM #NCTMDC23

SO EXCITED I got to meet Dan Meyer! “Make Yourself a Technology-Proof Teacher” was a wonderful reminder that teaching is the process of inviting, celebrating, and developing student thinking! “Students like and learn from teachers who like and learn from them.” NCTM #NCTMDC23

“Inviting, Listening to, and Leveraging Students’ Ideas: It All Starts with Noticing and Wondering” with @ClaireVerti and Notice & Wonder Woman Annie Fetter was a great reminder to accept ALL answers verbatim without “revoicing.” Check out my cool new laptop sticker! NCTM #NCTMDC23

😍😍😍

Good morning, DC! Ready for another day of inspiration and learning at #NCTMDC23! NCTM

Got to meet 2 more math SUPERSTARS today! 😍 Peter Liljedahl Tony Record NCTM #NCTMDC23

That’s a wrap! Thank you to NCTM for organizing another fabulous conference and THANK YOU to @LCPS_Math for the opportunity to attend! #NCTMDC23 #mtbos #iteachmath

Did you miss #NCTMDC23? Or did you attend and can't figure out how to find anyone's slides or handouts? Oh wow check it out they're all right here. 👇 conference-handouts.s3.amazonaws.com/2023-ncsm-wash…
