Hand-Eye Coordination
Hand-Eye Coordination is your brain guiding your hands based on what your eyes see.
Think of it this way
Your eyes spot a jar of jam on the far side of the table. Your brain reads the jar's spot and sends a signal to your hand. Your hand moves across the table and lands right on the jar. Eyes, brain, and hand work as one loop, each step feeding the next.
Explaining hand-eye coordination by grade level
Try to catch a ball that someone throws. Your eyes watch the ball as it moves. Your brain tells your hands where to reach. The faster the ball, the harder your brain works to keep up.
