S., yes, you are smart enough to teach your child and I think you are a wonderful mother who is interested in and trying to find what is best for your son. (And just for the record, you have very FEW misspellings in your post and they look like you were typing too fast)
Keep the learning fun during the summer. There is a website called Mathletics.com and it motivates a child to keep their math skills up. It does cost some money but I don't think that it is that much (we get it through our school).
For reading, I would go to the local library and join their summer reading program. It's free and usually pretty fun.
I would also have him write in a journal each day.
You could also go to a local teacher's store and ask their clerk to show you some good teaching books to use. If you explain what you want, there is sure to be one that would fit your needs.
Good luck....you are being a great mother, he is lucky to be your son!
