Common Core is all about evidence! Standard One for all grades is all about showing the evidence! This is a great Anchor Chart for Textual Evidence Sentence Starters- I would modify the language required for upper elementary and middle school students.
Language: CCSS This could be an anchor chart in the language center to give the students support of making sure their sentence is formed correctly and has correct punctuation. CCSS The students would be able to communicate their sentences with a peer.
Another teacher wrote: Always Write: An Original Writer's Notebook Lesson from Corbett. One of the most amazing writing sites I've ever seen and explored! If I ever teach middle school or high school English again - this site will be a best friend!
