VideoText Interactive Homeschool Math is an educational materials company, specializing in multi-sensory programs, for middle and high school mathematics (Pre-Algebra, Algebra 1 & 2, Geometry/Trigonometry). The focus is on the “why” of math, not just the “how”. Mathematical concepts are taught, not shortcuts and tricks. The instructional strategy is in 5/10-minute video lessons, using computer graphics, supported by course notes, student worktexts, solutions manuals, progress tests, and instructor’s guides, plus access to our TOLL-FREE HELP LINE at no extra charge for both our Classic and Online versions.
