Combining Ancient History

I’ve been looking through the six module cycle for history. My son (L) will be starting first grade soon and going through each history module as is would work great for his high school credits. But when I factor in his youngest brother (N), he wouldn’t get through the cycles in a neat order to get all of his high school credits. For N we would eventually have to double up history on top of a government curriculum.

So my thinking, was to combine the ancient history modules 1-3 right from the start (grade 1). I’ve seen other forum posts talk about doubling up, or removing Bible and neither one seems a good option for us. Possibly too much work for a grade 1 with a toddler in tow and I really want the feast of biblical history.

My thought was to split the ancient history modules into terms like so:

First cycle through – work through  term 1 of each ancient history module

Second cycle through – work through term 2 of each ancient history module

Third cycle through – work through term 3 of each ancient history module

So each time through we get a little bit of each but it’s new material and it covers a year. I know it jumps out of chronological order but keeping a family book of centuries may help with that.

I think the credits would still work for high school… from the samples each ancient history module is 1/2 credit history.  By doing 1 term from each module every cycle, would still equal 1/2 a credit history each year.  I’m assuming 1/6 credit could be assigned for each term…

I’ve only looked through the samples so I don’t know if that means some books will be left unfinished. Would that be an issue? Will the boys have trouble with ancient history being learned this way?

I would love and appreciate any thoughts on if this would work or what issues I might run into?
