Lorietta, for that age, I suggest reading aloud a variety of children's books (fiction and non-fiction), follow their interests as much as possible, visit museums and zoos, take them on field trips, let them watch educational television, visit educational websites, etc.
If you want to introduce handwriting, I like the Italic Handwriting series (for print - I don't like the cursive part for various reasons). It's available here: http://www.handwritingsuccess.com/
If you want a structured math program for this age, consider Math U See: http://mathusee.com/ or Miquon http://miquonmath.com/ (both use manipulatives - read reviews from current users and look at the samples/demos at the websites). There are other math programs, too... these just immediately came to mind.
For science and social studies, I'd definitely stick with the books, field trips, etc., that I mentioned above. It's much better than textbooks.
I also love the magazines available for this age, Ladybug and Click (see more info here: http://www.cricketma...m/kids_home.asp).
If you want more of a structured curriculum, one that's less school-ish than others is Five in a Row - here's a link: http://fiveinarow.com/
I hope others will come in a share their favorites. When you get a chance, read through my FAQs for more info about homeschooling (http://www.carolinah...r.com/afaq.html).
Let me know if you have any other questions.
