I hate to admit this, but I don't know.  Our state has, right?

Yes we have it and I hate it. The teachers do to and we are having a lot of resistance and protest in our school system which is creating the waves we need to make it know how awful things are. We have many teachers moving away from it and letting kids opt out of testing. 

I understand have a baseline that all children need to meet by the end of a grade. I find these programs (and they seem to cycle through every decade or so with a new name) limiting to teachers and don't address the needs of those falling behind or those gifted ones who are charging ahead!

Is that like the standardized tests they've been using to test proficiency in various subjects?

Ugh! I miss the days before Common Core. We have taken to Facebook so many nights trying to get anyone to help us figure out what the heck we're suppose to be doing. I've had to write notes to teachers admitting we know the answer but can't get to it with the method stated. My dad use to always tell me growing up that the great thing about Math is that it never changes...Common Core proved him wrong! 

I have seen some of the common core Math and not crazy about it. I much prefer how Math was taught before common core.

See I am wondering how my son's teacher will be this year because the one last year let them solve the math any way they wanted as long as they arrived at the right answer. Given my husband is a mathematics professer we think it is nuts how they are teaching them. However my friend says her daughter is doing so well with it. We are newly into it and like I said there is a lot of rebelling against it from teachers, parents and kids so I am not sure how it is all going to play out in the coming years.

yes, I agree...everyone does learn differently!
