Plastic Visual ASD Morning Routine (Picture Communication Symbols) Uses only high quality picture communication symbol images by Mayer-Johnson (used with permission). These are the most common visual symbols to be used to support the learning and development of those with learning disabilities, and therefore will be the easiest for individuals to understand and begin to implement. Made from plastic for great durability - durable, waterproof and resistant to grease. Boards and symbols all come with good quality sticky backed velcro, pre applied so products are able to be used immediately upon receipt. Ideal for helping your child get ready in the morning. All corners have been rounded to reduce the likelihood of scratches.
