Agreed - it has been a virtual desert out there for homeschooling material for high school students as far as math and science...really for all subjects. A lot of the homeschool curriculum companies focus on gradeschool level. Saxon math doesnt work for everyone and history has been a real issue for us. Fortunately, Ive been able to look at a variety of things because of forums like FR and some blogs I like to read.
I - and I hate to sound critical of my parents - consider the first two of my three high school years to have been a the waste other than Saxon and some of my enrichment activities. The curriculum she used for me was fairly useless. What good it did was in essays I wrote or books read; most of the assignments were a waste. My last year of high school we figured that out, transitioned me to community college, and spent the year reading things like the writings of the Founding Fathers and writing essays and research papers. Much more useful, but not what we could have achieved.
I personally love Saxon and plan to use it with my kids but I know not everyone does.
It’s going to be really interesting for me starting to homeschool; my parents’ new kids (adopted from foster care) are 18 months and 3 years older than my daughter. I might steal resources from my mom, or suggest different ones for her.
