A friend of ours who’s not particularly religious, used Switched On Schoolhouse by Alpha-Omega Publications for her 14 year old and they both loved it.
I don’t know how you feel about using the computer for a child as young as yours.
My opinion, and it’s got nothing to do with religion, is that the less exposure they have to TV and computers at that age, and the more to books, the better.
You might want to read *Better Late Than Early* by Drs. Moore and Moore about early childhood development. It’s a fascinating book.
Switched on Schoolhouse doesn’t start until 3rd grade
