It can be difficult for children on the autism spectrum or with severe impulsive behaviors (such as ADHD or Down syndrome) to discern which sorts of objects around the school are theirs to touch, and which objects are off limits due to unwritten social rules. These signs are great for cutting out and laminating, then attaching to various objects where the teacher would like to reinforce expected behavior with regard to public vs. private property.
My teacher's chair. The interactive white board. Other children's cubbies or backpacks. A favorite electronic device. Personal space with friends! Even that door handle that leads to the playground. All of these things can be misunderstood and so when we attach a visual like these Permission Cards (invited to touch) or Prohibit Cards (not okay to touch), we make it clear and provide a teachable moment to express which objects are okay to be near or control.
To generalize the skill it is recommended that the classroom be fixed with several labels, then as the behavior is learned and followed appropriately, the signs can be taken down one by one with each successive mastery of the student behavior.
