This is a graphic organizer that I use with my students to improve defining and describing skills. It focuses on their ability to define a word by it form (looks like, feels like), function (what the item does or is used for, place (where you will find it), category (what group it belongs to), materials (what it is made of or it parts). The visuals help non readers.
I have seen a great improvement in oral communication in using this tool. It can be used alone, with content vocabulary or mixed in with your literacy units.
