I am writing my own curriculum this summer, pulling from many resources. Last summer, I was all about “CGI” and figuring out how to use that approach more in my teaching. That led me here, and my teaching is 1000x better for it. As I research this summer, I keep hearing about “CPM.” I am not a trained math teacher, and I don’t teach in a public school, so I am often last to the party when it comes to new curricular ideas. The website description looks and sounds like it uses a lot of concrete models, offers interesting approaches, emphasizes problem-solving, etc. Anyone have any experience, good or bad, with this program? I’m trying to be picky, as @Jon says, and at the same time thinking how nice it would be if at least some of the activities were curated for me.
