This is from Nothing New Press about Christine Miller's Story of the Ancient World :
What stage / age of children is this book appropriate for?
"This book, like all the others in the Guerber history series, is meant for a child’s first introduction to the history of the ancient world. It was written with first graders in mind, which is the age we recommend it for at Classical Christian Homeschooling. It is too advanced for a first grader to read independently, but very appropriate for a history read-aloud to first graders, or any other children in the grammar stage. The content covers the events of ancient history and the Old Testament, and as such children will encounter sin, crime, betrayal, and rebellion against God, as well as repentance, faith in God, heroism, and many examples of God’s faithfulness to men. Although we encourage everyone to use the Guerber histories, including The Story of the Ancient World, with their children in the grammar stage, or first through sixth grades, we have heard from many parents whose teens read these histories with great enthusiasm."
Maybe I'm in the minority, but my 9 yo dd is reading CtC's history spines by herself and she's fine. She doesn't care for the Christine Miller book but she understands it. She's doing all of CtC but the painting part of poetry and we are doing IEW in place of Write With the Best. I also add SOTW to round out history a little.
Can you read the spines together? Or cut down on some of the written narrations and do them orally? CtC did NOT work for my ds who was 12 when he was in it. He couldn't keep up with the notebook pages but the reading was a breeze for him. I think HOD is wonderful when it fits your child but when it doesn't fit, it's drudgery. I bought it for my ds, sold it after using it for 8 units and bought it again for dd.
