ck-12 FlexMath

I am using a ck-12 textbook for the first time this year, I've written about it in earlier posts. The ck-12 people also provide a free, interactive practice site called FlexMath. It's designed to let students learn algebra at their own pace with the help of a teacher. It is broken down by algebra concept, each concept has resources for teaching and practice. I think the practice resources look very useful. I will be trying it for teaching equation solving, I think it looks especially useful for graphing linear equations
