<u>EXPLANATION:</u>
Children with fine motor skills exhibit more finely tuned movements such as finger dexterity. The fine motor skills coordinates the muscles like fingers and hands, with the eyes to complete the tasks perfectly. Kids with fine motor skills can easily perform sewing, playing guitar, writing and handling spoon and fork.
Fine motor skills can be achieved only when the kids learn to use the muscles in the hands, fingers and wrist. To improve hand eye coordination in the kids, they should be introduced with some fine motor activities like picking and grasping pom-poms, turning pages, buttoning the clothes and using keyboard.
