Our favorite history curriculum, hands-down, is Linda Hobar's The Mystery of History. CBD has it on all on sale right now for 30% off, which is a great deal. The companion audio CD's (think: fold laundry, make dinner, knit, write a letter, etc. while the kids are listening) and enrichment project and art packs are all on sale, too!
You can read about why we love The Mystery of History here. Maybe it's the perfect history curriculum for your family, too!
