This is posted in support of the mini-session I’m leading at CMC-North Mini-Conference. A session description for those who might stumble across this post:

Many topics in math seem difficult to address conceptually and tend to be taught procedurally. We’ll explore technology tools that encourage students to “notice and wonder”, talk about and make sense of mathematical situations, and develop conceptual understanding of triangle properties, linear equations, systems of equations, factoring trinomials, calculus concepts, and more.

My thanks to everyone who came to the session.  As promised, here’s a copy of the session handout [pdf].
