Scholastic book orders are full of descriptive words. Students can go through a book order and find interesting and descriptive adjectives to place on their adjective tree. I have students keep these in their writing journals as a reference tool for their writing to give them ideas for descriptive words. You could also add some “boring” adjectives (sad, happy, fun, etc.) to the tree and have students go through the book order and locate more descriptive synonyms of the words.
