Design or purchase a preschool curriculum. The curriculum should focus on language, math, science, manners and any other topics that your local school board requires children that age to learn.
Focus on schoolwork for a few hours each day, working one-on-one with your child to help him fully understand the work.
Take her on educational field trips once a week. For example, visit the library when learning new language topics or take a trip to a local science center to provide examples of how science works.
Read him plenty of books that teach valuable lessons and topics. There are thousands of preschool books available that help kids to learn about letters, numbers and valuable life lessons.
Practice hands-on learning to help your child really grasp the lessons you're teaching. One fun technique is to practice safe science experiments that lead to different chemical reactions. For artwork, mixing paint colors helps young children really understand how two colors can be combined to create a new color.
Work learning into your daily living. Find situations to explain things and encourage asking questions. For example, explain what is happening when you see workers fixing something outdoors. Question your child, as well, to decide if she is learning well or needs to work on certain topics.
