Teaching style

I am passionate about helping students find joy and success in math. In my classroom, students talk about math with their peers and learn by doing. I love an activity-based classroom where students are engaging in math in a variety of ways, grappling with problems and showing up as leaders. Every student has a strength to offer in the math classroom; they just need to opportunity to show it.
