Links to online resources for two-minute proofs have been added for Algebra I, Geometry, and Algebra II. Two-minute proofs are quick demonstrations, proofs without words, or informal explanations that can be used in a classroom as an introduction or summary of a concept. The inspiration for these links was a workshop co-facilitated by Bobson Wong at Math for America called "Two-Minute Proofs." Bobson is a three-time recipient of the Math for America Master Teacher Fellowship.
