Hi Cindy,
In our homeschool, we just use a history spine and I fill that in with living books and documentaries. That said, we did join a CC-like co-op three years ago and here are a few more things we do:
-we have a weekly history memory sentence. This week it is about the Monroe Doctrine. I don’t necessarily try to fit our history to each specific memory verse, but when we reach the Monroe Doctrine in our history the kids will make the connection (esp. my 13YO and my 9YO).
-our co-op also has a history timeline, which we do use in our homeschool. My two older kids have already memorized the timeline beginning to end. I like it because it allows them to have a general understanding of when something happened, and that, for example, the American Revolution was before the French Revolution. Later on, as we study each time period in more detail, they’ll learn the connections between the two, etc.
So, I’ve found that the history work in our co-op greatly enhances our history at home.
