This product has two components. The first is an "If - Then" chart with multiple options for the "then" component. The basis for using this chart is when you have a child that needs a very consistent and reward based schedule.
"If you (task to complete), then you can (reward/break)."
I find it is best to laminate the chart and the option pieces. Then use Velcro to move the pieces on and off the board. I usually write the task to complete on the chart using a dry erase marker.
The second board is for visually showing where the student will take the break. I find it best to determine this before starting a task, so the break is efficient.
