Steven Kellogg is one of my favorite authors, and his books definitely lend themselves to the word choice trait. I particularly love to use Kellogg's versions of Chicken Little for word choice since you won't find the word "said" anywhere in this book. While I read the book aloud, students list words used instead of said on an index card. Then we share out and make a master list. On a subsequent day, students work in partners or small groups to categorize the words from the chart. I allow each partner/small group to determine the categories themselves. This leads to interesting discussions.
