Speak in calm, neutral tone

Provide student with two or more choices, e.g., “you can either do your work sitting at your desk or sitting at the table”

Have the student decide in 10 seconds, or you will choose for them, e.g., “I gave you several choices. If a choice isn’t made within 10 seconds, I will choose for you” (this prevents the choosing process from going on all day)

Present the entire class or group with choices when assigning work, e.g., “Students, you can either do the odds or evens, you choose”

Give choices when rewarding, e.g., “Johnny, do you want computer time or a fancy pencil?”
