Thank you all for your feedback. I think I am leaning towards Mystery of History, but I could go either way.
OhElizabeth, I appreciate your concern that I would be doing too much in history (or overall). Ariana is advanced for her age, even if she is only 4, and has a 5th grade reading level. We read all the time, daily. She reads chapter books alone. It bother her not that there are no pictures. I do plan on "taking it easy" this year, and not having too much pressure. I realize she's starting ahead of the game, but she wants it, needs it. We did K with her last year, and she loved it. She is completely ready for first grade. We are starting the Little House books, have read The Lion, The Witch, and the Wardrobe (I read aloud first time, she read it three more times before we had to return it to the library), The Secret Garden, Dr Doolittle, and more on that level. We definitely read a variety of books, and will continue to do so. I prefer to read the larger books aloud first, and then she can read them to herself (I enjoy them, too!). I will gogle the old boards.
HappyGrace - Ariana is entering Year 1 ("first grade") this year. I agree TOG is thorough and doesn't need to be added to. I was more wondering if I should use a spine to replace the books TOG recommends.
Janice, "Read, think, write" is good to remember. I will checkout those books you mentioned. You're right, self-education is very important. I look forward to studying TOG with her. Books on CD is a good idea. Thanks for all your advice :)
After doing more reading on SOTH and MOH, I am leaning towards MOH. I guess my question should be, can MOH be used in addition to TOG's recommended books, or in the place of TOG's recommended books?
