Math without borders

Math Without Borders offers self-paced high school math courses that pair Foerster’s textbooks with video lessons and problem walkthroughs. Created by veteran teacher David Chandler, the program covers Algebra I, Geometry, Algebra II, Precalculus, and Calculus through downloadable or disc-based lectures plus assignments from the texts. Parents appreciate that instruction comes from a real teacher who works each example slowly, making a challenging book more approachable. Once purchased, families can reuse the materials with multiple children, improving value over time. It’s best for motivated teens who can pause, rewind, and take notes independently; some may still want occasional live help.
