The Earth seems flat for us living on it. If it were the shape of a cube, only those living on the cube’s edge might suspect something strange is going on. But what would be the “degree” of that strangeness? Could we get a measure of the overall “non-flatness” of a cube from what those on the edge report? We’ll explore these peculiar, amorphous questions and whether the cube is, actually, just as round (aka “equally flat”) as a sphere.

This is a two-session master class. In the first session, teachers learn from the master. In the second, participants have a rare and valuable opportunity to exchange ideas with other brilliant teachers. Participants are assigned a small amount of homework to prepare for each session.

Dr. James Tanton earned his Ph.D. in mathematics from Princeton University. He is an author, a consultant, and ambassador for the Mathematical Association of America, chair of the Advisory Council for the National Museum of Mathematics, and a founder of the Global Math Project, an initiative to transform the entire world’s perception of what mathematics can, and should, be. James has taught mathematics both at university and high school institutions. He advises on curriculum, consults with teachers, and gives demonstration classes, lectures, and professional development sessions across the globe. He is also a recipient of a Joint Policy Board for Mathematics communication award.
