Winner of tonight’s “most succinct post PACKED with ideas” award. #ElemMathChat

A few strategies:
-using turn & talks to allow students to rehearse and also cross pollinate ideas
- using “math talk” moves (eg rephrasing, repeating, etc)
- using math language routines, like stronger & clearer and collect & display
- sentence frames

Yes! Connecting - one of the 5 practices. So important. I feel like this is an area of growth for me. #ElemMathChat

A2: I am a fan of sharing 2 or 3 different approaches or solution paths for a problem and having students make connections between them. Having them note where aspects of the problem appear in the different student work. #ElemMathChat

Yes! We have to do what we want our students to do! So powerful! Part of growth mindest learning is vulnurabilitiy learning! At the end of Unit zero I share this quote - on my vision board- every year! #ElemMathChat

A1: Start by having routines from the beginning of the school year where exploring and conjecturing and asking questions are built into the math. That way, sharing ideas as they form is just part of the culture of learning. #ElemMathChat

One of the most influential mentors I’ve had is @akademic67.bsky.social. Her ideas, her depth of care, her fight, her wit, and-of course-her shoes…all unparalleled and impeccable. Everything she is and does for kids, for teachers, for education is what we should all aspire to be and do. #NCSM25
