I am currently taking a class offered (free) by our state on teaching math based on the common core state standards (which I have not bothered to read yet). The basic concept of getting the kids to model problems using blocks, pictures, etc. is great. The idea that the traditional algorithms for addition and subtraction will not be taught until the fourth grade--I'm not sure. Plus, I'm supposed to be in the grades 6-12 section, but all we've done is look at different ways to add or subtract numbers.

So, have any of you taught math using these standards/methods? What is your experience so far? Do you have any on-line resources for using this in algebra and beyond?

Thanks.
Kathleen
