Engage the child in a game of "Simon Says." Get the child to imitate the way you use large muscles, such as making large circles and then smaller circles with your arms. Stand on one leg and then on the other to help promote balance.
Draw a hopscotch board on the ground. You can do this with chalk outdoors, or with painter's tape in the house. Hopping from one square to another will help 4-year-olds use leg and foot muscles with more precision.
Play ball as often as possible. Throwing and catching promote hand-eye coordination as well as control over the arm and shoulder muscles. Kicking a ball back and forth or trying to kick it through a goal develops leg muscle coordination. Rolling the ball on the floor back and forth or knocking appropriate items down are fun ways to practice indoors.
Set up obstacle courses. Indoors or outdoors, obstacle courses give children the opportunity to develop control of their muscle groups. Obstacle courses should change from one activity to another, such as going from walking to crawling to climbing, or require sudden changes in direction.
Get lots of art supplies and encourage children to do arts and crafts. Coloring, tracing, cutting with scissors, using stickers and rubber stamps, using glue or tape require careful manipulation of the fingers and hands, without using the entire arm.
Place some small items on the floor, such as crayons or small toys. Play a game by having the child pick up the items with his toes. This helps develop eye-foot coordination and the use of individual muscles in the foot and ankle.
Use a flashlight to practice improving hand-eye coordination. Turn off overhead lights, draw shades or curtains. Call out an object, and tell the child to find it with the flashlight beam.
Let the child practice dressing dolls or play dress-up so she can practice on clothes. Snaps, buttons, zippers and lacing shoes help children develop finger dexterity.
