Bob Hazen does a lot of things with math. He has taught for 33 years, including 27 years in full-time secondary mathematics, 14 years as a homeschool dad, and 15 years as Algebra-2 tutor for a homeschool academy. For several years he wrote a math column for a national homeschool magazine. In the 1993-94 school year, he was project director for a pilot program in which algebra, calculus, music, and manipulatives were used to teach math to two regular first grade classrooms in a traditional school setting. Bob also founded SAI: the Summer Algebra Institute for Kids. SAI is a half-day, week-long math enrichment program in which color, shape, size, texture, music, manipulative, math symbols, and hands-on activities are used to teach substantive algebra to students with a wide range of academic abilities in grades 3-7. Over 4,000 students have attended SAI since its 1995 founding. Bob has also served on adjunct faculty at several colleges, has been a frequent speaker at homeschool conferences and at state and national math education conferences, and has consulted with numerous homeschool coops.
