Khan Academy, the free Web-based tutorial program, landed on the education landscape in about 2011, when it was featured on the popular weekly news show "60 Minutes." The program is now used worldwide by more than 10 million learners each month and is used in more than 29,000 classrooms in 216 countries. Are classroom teachers using the program as envisioned by its founder Salman (Sal) Khan? Unfortunately, from the observations of the author, many are not. Ineffective use of any instructional strategy could increase students' rampant dislike of mathematics and jeopardize reforms aimed at increasing mathematics achievement. In this article, the author describes the Khan program and how it can effectively be integrated into the classroom mathematics curriculum.
