Leapfrog and Reader Rabbit software was enjoyable when my son was young. When he was older, I searched for and found other educational software that didn't involve shooting or blowing up things. I used that as something he could use when I needed a break but was still feeling anxious about him "falling behind".
In general, struggling readers usually benefit from being read *to*. If she's willing to sit beside you as you read, great! If not, you are still improving comprehension skills, especially if you talk about what you read. What did you like? What did you hate? How would change or improve it? Which character was your favorite? These kinds of discussions (you talk about your views, too) work on comprehension.
Keep your eyes open to anything involving math and history, since those seem to be areas of concern for you. I found a book of math detective short stories. I used to play pinochle with my son (playing three hands, while he played his), and he kept score and added up the meld.
Blast to the Past and Crime Through Time are two good book series that reference historical events. Like the Magic Tree House (which we also enjoyed), these books open the topic and provide a springboard for further research and discussion of historical events. Another historically based series is Little House on the Prairie. There are additional books, written by other authors, about Laura Ingalls maternal ancestors, too. Even though I had a boy, I read them to him, and he enjoyed them. Farmer Boy certainly interested him more, and I sped through descriptions of sewing, but he found the farming and landholding aspects interesting.
Joanna Cole, who wrote the Magic School Bus books, also branched out into history. I can't remember the series name, because she only had one published when my son's taste in book changed, and he preferred Harry Potter and the like.
My son created a Wheel of Fortune game on the computer using spreadsheets, and learned spelling more easily by typing stories into WordPad documents, then copying them into Open Office documents, and running spell check. Using WordPad is important, since it doesn't autocorrect!!
Visit bookstores, libraries, educational stores, as is feasible.
Unschooling doesn't have to be all or nothing. You can bring unschooling possibilities into your everyday activities. Keep a notebook of what you've done for your records, and you have evidence for yourself or your school district that subjects are being covered.
