Ok....I would go through plans and pick and choose pieces. The Modern History in Pictures book could be used alone for year 4. Flesh out with added resources as you wish. Also The Century video series can vibe found in full on YouTube. Great for year 4.
I am a mama with severe ADHD and have all three programs. :)
I think it depends on if you are able to follow and check off the boxes or if you will change stuff up on your own anyway.
HOD has one full week samples. Try one out :)
I am "thinking" HOD and supplimenting with SL books may be your best fit.
I can't do any of them fully cause I have a horrible habit of adding and tweaking things. :D
Currently 3rd year of using tog and on year 4.... Doing mostly history readings, lit readings, and discussions via online coop once a week. I add documentaries and videos/movies. That is on a good week :) Nothing else right now.
