I am still fairly new and don't know all the titles that go with the age groups. I've heard them, and tried to quickly look up on CC's website, but couldn't find my answer. So, instead of the title of the age group, I'll say that I work with 1st-3rd graders. I know I've got some 6 yr olds, and 8's. I think/hope most of this could be adapted to different ages/levels. I hope you find this reply. I really try hard to get back to everyone who comments:) this is my attempt.
