Bring math to life with classroom-tested activities that connect geometric and algebraic concepts to real-world measurement and exploration, all designed to work within the four walls of your classroom. In this session, you'll learn how to run a Pi Day challenge using physical measurements, investigate special right triangle ratios through hands-on construction, and tackle a volume optimization task with nothing more than cardboard, curiosity, and a TI-84. Walk away with activities and strategies to make math feel more alive, relevant, and fun for your students.
