My first impression of schoolhouseteacher.com was: Wow there is a lot here. The content is deep, but it is also wide. They have lessons, created by expert teachers, for pre-k through high school for everything from the 3Rs to guitar. I like that they have lessons not only for many different subjects but also in a variety of time frames. They have lessons available monthly, weekly and daily. The best thing is though, the lessons are ready to teach right away. They also have an archive of past month's lessons as well.
The daily writing and grammar is great because it really took a load off of my shoulders. For the daily lessons I simply print off the one page worksheet for both writing and grammar. Zippy does them, we discuss. This gives me more time teaching and less time re-inventing the wheel.
I would highly recommend this website for any homeschooling family. The tag line says it the best, "Everything you need, for a full program or to fill in some curricular gaps."
