If you have students with autism or other disabilities who need the help of visual supports, you may want to examine the photos and examples over at Do2Learn. Picture schedules and visual directions can help students become more independent, learn unfamiliar tasks, and reduce their anxiety about new routines (e.g., checking a book out from library) and classroom activities (e.g., playing a math game with a peer).
Keep in mind that these supports are not just for students with disabilities; many students are more visual than auditory and can profit from visual models, directions, or rules.
