What is the main theme of Common Core? I have heard about people who disliked it for years. Now it seems some teachers like it. I mixed up Race to the Top with Common Core neither of which our state participates in....so we get no training in it. Is it anything like showing the kids different ways to solve math problems? My cousin ( Ohio) showed me the lattice for multiplication and I love it. The kids learn it so quickly that way. I show them because I think they are fun. It is fun to see them catch it in a day or 2, but I have to go back and teach it the regular way too because the teacher above me really does not like it. Is there a philosophy to it? Do you like it?
