Feed them breakfast. Hungry kids can't concentrate on anything but their hunger pangs. They simply don't have enough energy to listen to the teacher, read their textbooks or concentrate on solving problems. Get them to bed early. Kids who are rested are more mentally alert and able to focus on learning.
Sleep helps restore energy in their rapidly growing bodies.
Parents of children who reach their potential don't allow television, hobbies, computer games, sports or friends to come before school and homework. Stay in touch with teachers. Present yourself as the teacher's ally. Attend parent-teacher conferences, and find out how your child is doing. Ask for suggestions on what you can do a home.
