My Take
Overall I really liked this tool. They offered a number of lessons tied to one concept. Each lesson has an opener, guided practice and closer. They show each lesson covers the common core curriculum as well as offer IEP goals. I work with special education students and their case managers are looking at what we cover and how we covered that material or evidence of it. This site helps you with that!
How I Use It
This site offer a variety of lessons for math teachers. I plan on using this site in my class this fall. There are a number of lessons that tie in with the concepts I teach. These lessons offer an alternative approach to instruction as opposed to just standing up there lecturing. I see this site giving teachers various teaching paths and projects.
