This blog focuses on Algebra, Geometry, and Threee-Act Math. It provides curriculum-based lesson plans for math teachers. Three-Act Math is a great model for introducing math tasks to students. I plan on teaching K-2, so I would probably not use this blog often, as it is geared toward mathematics taught in middle and high school. However, the blog includes posts that will benefit teachers of all age levels (classroom management, assessment, etc.) I would recommend this website to upper elementary, middle, and high school math teachers.
Check out Dan's spreadsheet in which he has listed the Three Acts of several math tasks!
