BLOSSOMS - The Broken Stick Experiment: Triangles, Random Numbers, and Probability with Professor Richard Larson

Video Summary: This learning video is designed to develop critical thinking in students by encouraging them to work from basic principals to solve a puzzling mathematics problem that contains uncertainty. One class session of approximately 55 minutes is necessary for lesson completion. First-year simple algebra is all that is required for the lesson, and any high school student in a college-preparatory math class should be able to participate in this exercise. Materials for in-class activities include: a yard stick, a meter stick or a straight branch of a tree; a saw or equivalent to cut the stick; and a blackboard or equivalent. In this video lesson, during in-class sessions between video segments, students will learn among other things: 1) how to generate random numbers; 2) how to deal with probability; and 3) how to construct and draw portions of the X-Y plane that satisfy linear inequalities.

If the students are asked to the no. of possibilities after they have understood the probability of forming triangles. This could possibly lead the students to explore the concept of infinity (in terms of real numbers)
