Quiverfull,
Thanks for sharing a bit more information. That does help as we ponder how to award credit for the work your students completed this year.
In considering that your 9th grader did the last half of RTR and the first half of Revival to Revolution, I would be inclined to list the history credit for the combined work he did as Western Civilization I on the transcript. This will work due to the content coverage of history being world history (which includes the history of western civ) in RTR and world history (which again includes the history of western civ) combined with beginning U.S. History (again western civ) in Rev2Rev. This would mean that in the remaining high school years he would list MTMM as U.S. History II (or even just plain U.S. History with no number behind it), and then list World Geography, and World History for his remaining high school credits for history as he completes them. This would allow him to earn all needed credits in history.
For science, I am thinking it would be wise to have your 9th grader complete the rest of the Advanced Kit from Rev2Rev to earn a full credit of Physical Science with Lab for high school. So, you could either have the 9th grader work on that through the summer to complete it, or you could have your student pick it back up in the fall and complete it then. After that he would move on to the science in MTMM. One other option, if he plans to follow the path of doing Chem. with beef-ups in MTMM, IPC with World Geography, and Biology with World History (following the scheduling in those guides for science for the most part), then you could potentially forego finishing the Exploration Education Physical Science from Rev2Rev and just award a half-credit in Physical Science for what he has completed and be done with science for his freshman year. But, you would then have to be sure to finish all three remaining sciences with lab for high school credit in MTMM, WG, and WH (which is very doable.)
For English, for your ninth grader, if your student did some combination of DITHR, Rod and Staff English, the last half of Medieval History-Based Writing Lessons from RTR and the first half of the Exciting World of Creative Writing from Rev2Rev, you could award a full-credit in English I.
For math, if your 9th grader did Algebra I or above, you can award a full-credit in math.
You could also probably list a half-credit in Bible for what was covered hour-wise within RTR and Rev2Rev, although that will be a bit of a stretch. However, since it is an elective credit which has more leeway, it would work for his ninth grade year.
At this point, with the work your son did, he pretty much finished a full guide this year, so he can stop Rev2Rev (except for possibly the science - depending on what you decide to do with that) and move onto MTMM (due to the fact that he will be a 10th grader this coming year). Typically, we wouldn't advise skipping the last half of a guide, but with your student's age in mind and the fact that he did complete a full guide pretty much this year (between finishing one guide and doing half of another) it would appear he is ready for a full guide like MTMM as a 10th grader.
One possibility you could consider for the upcoming year is doing school 5 days a week for your high school students during your more focused school months when it works (doing a full day in a day if possible for your olders only) to allow them to move more quickly through the guide on the weeks when schooling is going well. Then, you can downshift with your high school students to 4 days a week on the busier weeks. This allows the older students to get ahead a bit when things are going well. We school 5 days a week here all year, as our busy season begins earlier every year!
For your tenth grader, while not ideal to have that many weeks remaining, it is doable to count credit with what he has completed. It is true that schools often finish only 75% of the textbooks and are able to count credit for that so we can apply that strategy here if needed too.
So, your tenth grader would list MTMM as a full-credit of U.S. History II, a full-credit of Chemistry with Lab (if he did the suggested beef ups of some sort with the Chem.), a full-credit of English II since he is a 10th grader (if he did WWTB II, DITHR, and Rod and Staff English), a half-credit of Bible (if he did the Bible as written in MTMM), and a full-credit of math (if he did Algebra I or above). If he added any foreign language, you would list a half-credit for that. If he added to the Economics study in MTMM, you would list a half credit of Economics. If he didn't add the foreign language or the Economics it will be alright. We can work those in his last two years.
With this plan, your 10th grader would move on to World Geography and start fresh next year. He will need more time for that guide as it is a definite step up from MTMM. So, he may want to consider the 5 day plan for the weeks that it works for him as well (which I also mentioned as a possibility to consider for your 9th grader).
I know that life gets busy and that things often don't go as planned. Just keep on plugging knowing that the Lord has the plan. Your kiddos did progress this year more than you think. They have actually earned the credits that you are recording, so you need to feel good about that!
They are still on a good academic path for high school and will each get through their needed credits by graduation if they stay the course.
I hope this helps!
Blessings,
Carrie
