Maggie,
Hello and welcome to the boards!

I used CTC last year with my then 9th grader. It went very well and we enjoyed it very much. The reason I used it for high school was simply because we were new to HOD and thought it would be good to start at the beginning of the history cycle. I now realize that there is so much more to HOD guides than just the history time period! There are so many skills woven into each guide in the areas of language arts, life skills, and writing ( I am sure there are more). So if you were able to put your child in the guide that they place in best on the placement chart as Carrie suggested, this would be ideal.... but since you stated that
I can not afford to buy 2 programs,
It seems that using CTC for both children best fits your family. I would be glad to share what we used last year to beef it up and make it high school worthy. We loved everything and it was a great fit for us!
We did EVERYTHING in the CTC guide EXCEPT for the "Science Exploration" box. We added the extension readings and extra stuff( I will list in a minute) to up the level of history reading. Then we did high school level math, language arts, and science. This is what we did in list form and most of it (if not all) is compiled from Carries suggestions.
History- CTC guide plus extensions (including the extra narrations etc),
The Archaeology Book by David Downs
Our Young Folks Josephus by William Shepard
Unwrapping the Pharaohs
Plutarchs Lives for Boys and Girls by W.H. Weston
Caesars Galic Wars by Olvia Coolidge
Bible- Bible in CTC giude
Balancing the Sword- studying books of Job, Daniel, Philippians
Literature-CTC guide ( for written narrations, dictation, writing(Write with the Best 1), and poetry study)
Drawn into the Heart of Reading (using high school level books for each genre and workbook 6/7/8)
Rod and Staff level 7 (half of the book, reserving next half for 10th grade)
Math- Video Text Algebra
Electives- Shop coarse by Pacworks
Foreign Language
Also Bible fits here
Science- Pacworks Physics and Chemistry 1/2 for 9th grade and other 1/2 for 10th(this is actually worthy 2 credits)
We read the extra history reading in the order that I listed them. We enjoyed everything listed here and it worked very well for us! My son had not had a lot of writing experience (one of the areas I had slacked in), so we chose to do only WWTB 1. I think Carries says that it is best to have the child do both Write with the Best levels 1 and 2 for the year. Also, I assigned grades to his student notebook and his poetry reciting to add to his DITHOR and writing grades for an overall Literature grade at the end.
I hope this is helpful. If you have any questions ask away. Also I would be glad to tell you exactly what HOD materials we ordered for our 9th grader to do CTC in this way, if that would be helpful?
