4th grade S.S. in our school covers our state, Ohio. GS9 is finishing up a report on Native Americans. They've done a bit of studying about the land forms. This book, Ohio plants and animals / Marcia Schonberg, complemented their S.S. books very nicely. She has other books about Ohio, covering people and history that complement his S.S. book. These were all available at our local library. They're a nice overview of Ohio, written at 6-7th grade reading level, middle school interest level. And if you find something you want to study more in-depth, go for it! GS9(that stands for Grandson 9 yr old) goes to public school but we do a lot of life-long learning activities on weekends and after school.
