I was about to recommend starfall...it is AMAZING. You can also print out pages to go with the online activities. Remember that boys develop language skills behind girls; one of the problems with Kindergarten in schools is that it is geared towards girls. Many five year old boys are not ready to learn to read. I have homeschooled my kids since day one. My oldest is a girl, and she learned to read in K. When my son started last year, I knew right away that it was too soon for him. We concentrated on learning letters and simple math. He's in first grade now, and learning to read is going extremely well because he's ready now. Kindergarten shouldn't be too focused on sit down work; it's more of a time to begin to expose your child to things.
As for public schools helping kids in need (which it doesn't sound like your son is-he's just a normal five year old boy), I have to respectfully disagree with the PP. I have a Masters in Education and was a public school teacher. My best example of "help" is a fourth grade boy I taught. He had recently moved to our state, and this was his first year in our school district. I knew from the first week that he had some learning disabilities. He wrote the most imaginative stories of anyone in the class, but his spelling, grammar, and handwriting were the worst I'd ever seen. I put in the paperwork to get him evaluated for special help during the second week of school. That department didn't hold a meeting to get him into those classes until the last week of school! Meanwhile, I used modifications for him that I used for my special ed kids within my classroom. He truly needed extra help from the special ed class, but he didn't receive it. I really tried, but he failed the grade (only child I have ever had fail).
