Typing on a Computer Keyboard. For some students, learning to type on a computer can be as difficult a task as learning to write with a pencil. Students with good fine motor skills are often better at mastering this particular skill. Typing requires coordinating finger movements and memory skills.

A motor skill is simply an action that involves your baby using his muscles. Gross motor skills are larger movements your baby makes with his arms, legs, feet, or his entire body. So crawling, running, and jumping are gross motor skills. Fine motor skills are smaller actions. When your baby picks things up between his finger and thumb, or wriggles his toes in the sand, he's using his fine motor skills.
