Hi - I just wanted to pass along a some great CCSS Math resources for you. The first one is get2MATH K-5 with links to many, many resources. Another is, The Michigan Department of Education has many resources for each of the standards, and it was brought to my attention by Dr. Nicki's Guided Math Bog. She has a ton of great resources available so you definitely need to check it out. I attended several of Dr. Nicki Newton's workshops in Chicago and she is amazing! Happy web surfing!
