Three years ago I made a swap in districts and grade levels, which was the same year my state adopted the CC. The adjustment was 'easy' for me because I really didn't know the difference. Everything I need to teach my 2nd graders was all I was familiar with. I'm curious to hear from others who haven't switched grade levels what the changes looked like. Can you share an example of an "old" standard with a CC standard for comparison? A thread from Giraffe (?) got me thinking. She said something about her standards being similar to one she was expected to learn as a kid....but 3 grade levels after...in an honors class! Any examples of rigor gone wild?
