Many districts now require teachers to display focus goals at centers, so Dr. Jean (http://www.drjean.org/) and I have translated the standards into "child friendly" language and made "I Can Center Cards" for each ELA and Math Common Core State Standard. We know that so much is required of all of us, and we thought this may help to lighten your load!
Copy the center cards ( 2 cards per page) on card stock, and cut them in half. Hole punch at the top, and secure each strand with a book ring. Flip through the book, and display focus goals at learning centers. You can also put magnets on back to display the cards if that works better for you. Feel free to adapt these cards so they work best for you and your students.
