Mimi has a post about a great lesson focused on the details of solving algebra problems, and catching and understanding errors. She’s taken a lot of great ideas and combined them into a fabulous lesson. You should go take a look!
Amy Gruen at square root of negative one teach math has found a way to teach piecewise defined functions that worked for her students. This is a really difficult skill for a lot of students, so this is a totally awesome lesson to read about–go read it!

I really love how Carolyn’s lesson on factoring polynomials using fractions tiles worked (go read it right now!). There are two things I see that made the lesson work really well: one is […]
