First, let me begin by telling you that I have a common core pinterest page where most of this stuff can be found! Click here to check it out. I have pinned many assessments, activities, and much more from blogs out there.
I have also included the common core app widget on the side bar to the right. Open it to find the standards for all grades and subjects. If you would like to get the common core app for on the go access click here.
Two new and useful blog sites...
If your like me and you love technology...here is a great new online practice platform for elementary grades. Best part is...it's 100% common core aligned and if that wasn't enough...it's free for teachers!!! Scootpad generates continuously personalized practices for each student with no intervention from the teacher. There is a downside to it though :( As of right now it's only for grades 1, 2, and 3. However, they are working hard to get grades K, 4, and 5 up by August.
Our schools Math Coach has always been a big advocate for CPALMS. This site has amazing resources for teachers in both math and ELA subject areas including lesson plans, assessments, games, and more. They are currently converting everything over to CCSS.
I hope these will help you feel better about all this common core talk! If I find anymore resources I'll add them to this post and my pinterest board too of course. :)
