Ray Harvey was professor of mathematics and physics before he had a stroke. Ray’s stroke brought him to hospital mute, blind and with severe aphasia. Then Ray learned that he couldn't add three simple one digit numbers together so he could no longer lecture and went into forced retirement.
To aid his recovery, Ray bought toys called “Twist and Shout” which are designed to help both hand movement and mathematical skills. Each toy focuses on one mathematical operation - addition, subtraction, multiplication and division.
Ray practiced with the toys for two hours a day and after six months Ray got his mathematical skills back.
The toys also have a headphone socket so there is no need to disturb others while you practice.
