We used the ACE Curriculum straight out of coming out of public school. Although it was nice to have a workbook with all the work in one- learn it then answer questions- I felt it did not go into enough detail and was very basic.
I was hoping this would teach more than what they learned in the public school but it taught quite less. They only had a page on each subject then move on. We covered WWII in 2 pages. I think this would be okay for an extra or maybe a guide but not alone.
Also, kind of corny jokes and comics through out the books which we felt were a bit old fashion.
