Once students are finished creating ads for The Lorax, you can have an ad party. Ask parents to donate food and drink items for the party to save on cost. For fun, you can decorate the room with Dr. Seuss items or even paper Truffula trees. You can display students' ads around the room with comment sheets under each one for positive comments only. As students are eating and drinking, they can walk around the room, view each other's ads, and write comments to their classmates. You can also have students give a presentation of their ad and tell classmates what advertising techniques they used when creating ads.
