I was going to write this in a comment, but thought people might want to refer back to it.
All 5 of my siblings with kids used Teach Your Child to Read in 100 Easy lessons. 17 out of 18 of my school age nieces and nephews were able to read chapter books by the time they started Kindergarten (two or three read all the Harry Potter books by the time they were out of kindergarten!). I will get that book sometime in the next year for Dean.
One friend who ran a tuition based preschool gave me some good sites:
I have another friend who runs a preschool out of her home and she has a blog where she says what they did that day. Great ideas from her. Most of her themes are around letters of the day.
When I start getting specific games made, I'll let you know where I got them.
