This infographic comes from the blog over at eyeoneducation.com. I particularly like the first suggestion, “Brainstorming with a Twist.” I often have my students brainstorm, but I have never thought of adding this additional challenge once they are finished. You can go here to view the book, Teaching Students to Dig Deeper: The Common Core in Action, by Ben Johnson, from which the infographic is adapted. There is a link on that page to download a PDF sample from the book.
