I'm sure there are lots of vocabulary lists out there for common core math, but I've been using one that I found from East Moline School District.
here to see the full list--it goes way on up to advanced vocabulary in high school. My kids are struggling with the kindergarten concepts, though. I've been surprised at how little they understand the language of math, and depend on adult prompts and cues and demonstration (even my regular education 2nd graders are lacking in many of the kindergarten concepts). Unfortunately for them, simple computation is a thing of the past.
I don't have any materials yet to teach these concepts, but will be developing some games and simple assessments on my own for the younger grades, so be on the lookout! For now, the list is useful, and it's easy to work on many of these with what you have already. I just found this list handy for keeping track of what the kids need to know, and what you have taught them.
