Have you looked at the Common Core Standards and felt a little overwhelmed? I know I have. I have created KID friendly Common Core Math posters for third, fourth, and fifth grade. I plan on copying my grade level posters onto cardstock, laminate them, and post them for students to refer to when starting a new concept.
You can find these posters in my TpT store.
Look for Language Arts Common Core posters to be available soon!
