Welcome S6R!
I can relate to your lack of confidence in the chronological order of history. 😉 Thats why I LOVE the SCM History Modules! Each module has all the books already listed in chronological order one after another. So in each grade division, you start with the first one first, the second one second, and so forth.
I’m sorry I can’t suggest a spine for Modules 5&6 since we’re only in 4. However, I’m sure there are some great suggestions in the bookfinder. What are the ages of your dc?
Blessings,
Heather
