Token Boards - great tool for helping motivate a student to complete a task, with a small reward at the end. Short ones are the best, unless you're trying out more of a long-term reward system, like a sticker chart throughout the day or week. You can print and cut out the tokens, or use a marker/sticker/or highlighter for each token. If you'd like it to be reusable, you can laminate the token board for durability.
