Living Math This is the efforts of Julie Brennan, a former CPA and current homeschooling mom in the San Diego area, who discovered her bright son loved to read but had learned to hate math.

She has started a living math forum (which you can join at her website) to support others interested in a more "living" approach to learn math and is in the process of writing math curriclum and publishing it through pdf downloads on her website.

Thinkwell Homeschool online packages provide a 12month subscription to their online video instruction, 50 hours extended support, interactive exercises, pretests, tests, and notes...for a very reasonable price (currently $125 per subject for the basic package described above). Subjects include 6th grade through 12th grade math (through calculus), and AP biology, chemisty, physics and American government. An optional workbook and video cd may be bought to supplement the online course (but are not sold separately). These are secular videos, so the subjects are taught from a secular view point, and the math is taught by a college professor who used to be a stand up comic and who has a bit of fun with the dry topics occasionally. However the math appears to be basic math concepts and humor overall clean. Subscription is not refundable so view the sample demos carefully first. The math packages are reviewed and recommended by Sonlight for homeschoolers (and sold through Sonlight as well).
