We found the book Oliver's Travls: An Ohio Adventure at our public library. My kids enjoyed reading it. It is a story about a mouse named Oliver who travels around Ohio with a map from his Grandfather. He visits various historical sites and landmarks. It was written by Cynthia Furlong who has a blog, and illustrated by Bruce Langton. My kids agreed probably a 3-5 th grade book.
I think it sounds like a great way to get some Ohio history into your curriculum that does not involve a large project. Your student could read this to fulfill the Ohio history requirement. An excellent resource.
Some great ideas to expand on the book would be to print off a map of Ohio and fill in where Oliver Travels. Here is a web page with many Ohio maps for you to choose from.
Happy Ohio History!
