I made these cards while working with students with IEPs focusing on attention issues. They can be printed (on card stock if you can) cut and laminated. Remember to also cut out the Good Job card from page two! I like to keep them on hand when we're at the carpet. Some teachers like them around their neck. Just hole punch them, ring them and string them if you think they will be more accessible. Accessibility is key.
I've added some additional blanks so you can make your own as necessary. You might have a biter. No biting is a great additional card.
