I used the 100 easy lessons as well. Worked wonderful! With my oldest (who was barely 5 at the time), I didn't get past lesson 15 and she was off and running on her own with it. Didn't devote as much time with my other daughter. she didn't read quite as early as the other one, but she is 6 1/2 now and reads chapter books easily (working on an American Girl book and has read several Junie B. Jones books).

We will see in a year or so if it works on one of my boys as well.
