Good CS High School Homeschool Curriculum?

dingo_kinznerhook writes: I grew up in a homeschooling family, and was homeschooled through high school. ( I went on to get a B.S. and M.S. in computer science; my mom has programming experience and holds bachelor's degrees in physics and math — she's pretty qualified to teach.) Mom is still homeschooling my younger brother and sister and is looking for a good computer science curriculum that covers word processing, spreadsheets, databases, intro to programming, intro to operating systems, etc. Does the Slashdot readership know of a high school computer science curriculum suitable for homeschooling that covers these topics?
