He is very quick in other areas of play and when helping around the house. He catches on quickly to games he wants to play and seems to be a leader when he plays with the other children.
What can I do to help him retain the information he learns? Do I need to seek professional help? I would very much like to get this problem under control before he starts kindergarten. I will continue to work with him throughout the summer.
You will be making a big mistake if you try to turn your child into a scholar before he is ready. Enjoy the fact that he is quick in so many areas, and limit how much time you spend on teaching him letters and numbers. Learning needs to be fun for him. Use rhymes and interesting letter and number books to make learning more enjoyable.
Remember that your son learned to crawl and walk when he was ready. The same principle applies to the skills children need for school. Guard against pushing him to acquire skills before he is ready. There is absolutely no evidence that formal instruction at an early age has any lasting academic advantage. It may even do some harm. Force-feeding academics to preschoolers can even cause kindergarten burnout. Don't be too concerned right now about your son's knowledge of letters and numbers. It is still some time before he will enter kindergarten, and all young children do not know their letters and numbers to 10 on the first day of kindergarten. Almost all, however, will have learned them by the end of the kindergarten year.
