If you have a student who needs help to stay on track, I have found this board to be quite useful. It allows for students to get 3 starts, once they achieve their goal they get to choose a free choice activity.
Included are a variety of free choice activities.
If you have a student who needs help calming down, then use the second board (I place them on the students desk). It has 4 strategies (sit down in chair, take 2 deep breaths, count to 10, happy again)
