IEW Geography or American History

Good Morning, Our children will be in 7th, 5th, 3rd, and 1st grades next year. I am probably going to use Notgrass America the Beautiful to teach them American History. For IEW, we have used the SWI-A with the three oldest kids, and this year are doing the Ancient History theme-based lessons with the two oldest and Bible Heroes with the second grader. Next year I would like to use their Geography-based lessons or U.S. History-based lessons. Any comments on these two theme-based courses and which you would recommend? If anyone reading this has used either course, could you comment on how long it takes to teach each week? Thank you!
