A presentation on Jai Alai, the Basque sport that is described as "the fastest sport in the world." Includes key vocabulary, a description of the equipment used and the rules of the game, and a video clip of a match.
I used this as an example presentation before assigning a project to report on a sport from a Spanish-speaking country. However, this could easily be used as a cultural activity/presentation during a sports unit.
Bounus points if you can find some jai alai-like equipment (or actual equipment) for the students to give it a try!
