Great Math Common Core Tool: Use to Plan Small Guided Math Lessons
While looking for Math Common Core materials, I discovered this cool tool that helps you to search the new Math Common Core standards by topic. You select the concept or the grade and then all the standards related to that topic pop up. It shows how the topics are developed over time across the grade levels. It also helps you to differentiate instruction for small guided math groups by being able to see what came before and what comes next.
