Why Has Math Changed So Much? Want a Cheat Sheet?

Are you one of those parents who sits with his/her child doing math homework wondering, when did math get like this?  Why is it so different from what used to be taught in school?

I have found that actually looking AT the new Common Core Standards for Mathematical Content and Practice can give great insight into why math has changed so much.   So much is in the media about how bad these math standards are, but if one really takes a closer look and the actual standards, it does not seem all gloom and doom.

Want to look at a few key pieces from the standards that will help you understand their math homework a bit more?  Here are a few key pages and links to the actual standards too!
