"When teachers understand math differently, students learn math differently. And when professional learning empowers teachers and gives them confidence and clarity, the momentum that follows is contagious."
When Teachers Understand Math Differently, Students Learn Math Differently
When I look back on the past two decades I’ve spent at Leander ISD, I think about how much elementary instruction has changed. I’ve been a third-grade teacher, a reading specialist, instructional coac...

Shifting the focus to problem-solving is not "abandoning accuracy. [It] is about raising the level of thinking we ask of students... We are asking [them] to reason, justify, listen & reflect. We are teaching that math is something we actively do & that their ideas matter." -@zakchamp.bsky.social

Constructing & drawing 3-D structures "raised up students who didn’t think of themselves as 'good at math' & gave others the opportunity to see & admire their strengths. Students also learned more about each others’ interests & experiences, & that knowledge led the class to go deeper with the math."
