Please consider joining the Thinkfinity Common Core group. We will be sharing information, resources, CCSS based lessons, and offering an opportunity to discuss topics and issues dealing with Common Core State Standards. Please feel free to post comments, opinions, and resources that you've found helpful. Common Core Standards are a national effort and I know we can learn from one another. If you have suggestions for topics for future discussions, feel free to share. Many states are providing professional development opportunities to their staff and it would be interesting to hear about some of those.
