I am trying to plan for high school math as my son with be a freshman this fall. We have been using Teaching Textbooks in 6-8th grades but was thinking of switching to Foerster with math without boarders for high school math. I am concerned though that I will not have the time for grading and keeping up with him in a more hands on program as I have 4 other younger children age 7, 5, 2 and 9mo. I love the Life of Fred books but am not comfortable with them as a complete program. Do you think I could have him do both TT and LOF to make a more college ready math program?
