Also wanted to start strong on Thinking Classrooms (@pgliljedahl.bsky.social) work after some struggles last year. Very grateful for @fawnnguyen.substack.com's piece on giving yourself permission to go off-script. Kids especially enjoyed the Chicken Nugget Task and showed so much thinking! 3/3

A classroom whiteboard with the numbers 6, 9, and 20 written in large font across the top. The board is filled with multiplication expressions, starting with the multiples of 6, then multiples of 9, then multiples of 20.

we filled up our class jars of Math-y activities. Ended up leading to a great moment of pointing out that we have succeeded in Math, even if we didn't realize Math was happening at the time! I was able to snap a photo of one student's Jar that captured some of the positivity of the lesson. 2/3

A student sheet titled "My Jar of Math Master". The jar is filled with examples of activities that "feel like" Math, including Lego, Time, Monopoly, and Planning. The sheet has been decorated with marker drawings of ribbons, a spider and its web, a rainbow, a unicorn, shopping bags, a cookie, and a flower.

Inspired by @themathguru.bsky.social's session at Calgary Teachers' Convention, I've been starting every Math class with low-stakes Math Talk question. Here was today's -How Many Do You See? (Dice Talk image via Dave. Martin)

A classroom screen displays a photo of an arrangement of blue and yellow dice with the title "How Many Do You Count?"
