It’s been awhile since we studied Ohio history, and both times we did it through a co-op. This was back when my youngest (now 10th grade) was in 3rd grade and again in 7th grade, and I didn’t personally choose the materials.
However, in an attempt to look back on books we’ve read that included Ohio history, I found a couple of resources you might check out. This blog is geared toward teaching geography, but there are some living history books listed. Another blog lists a few books for each of the 50 states. If you scroll down, you’ll find Ohio.
Also, I do recall reading The Wright Brothers by George Sullivan during our Modern History module. You can find more information about this book in the SCM Bookfinder.
