Prior to teaching the effective use of the calculator, equipment with visual and physical adaptations must be selected. Once the type of calculator has been determined, the groundwork for success can be laid with instruction and reinforcement as needed. Teachers must be diligent in the instructional use of such equipment, and often daily, repetitious instructions are required.

The ultimate goal, of course, is to assist in optimizing a students' abilities, and ultimately contributing to the promotion of their independence.
