Doodle games from closed lines and shapes on a plane. Fun to watch, and infinite variations! In the first example, the author invites you to "draw a squiggle, a closed curve that ends where it begins." Then she shows you how to turn it into a beau...tiful--and mathematically pure figure. She repeats this with two other exercises all the while quipping about how cool math is. (04:25)[more]

We revisit the philosophy department and the question of whether numbers really exist? Featuring Mark Jago from the University of Nottingham. Film and interview by Brady Haran Edit and animation: Pete McPartlan. (09:40)

Baby Dragon helps some third-graders by showing them his timeline project. The timeline project encourages kids to do "timeline math".Students have to use math from Baby Dragon's timeline to answer certain questions. (11:58)

Time to hype the American Mathematics Competition 2012 at Lusher Charter High School (New Orleans). Parody of the 1993 jam "Rebirth of Slick (Cool Like Dat). Doesn't really go over many topics in particular, but it does focus on a few. It is mostly j...ust a song about loving math and being "Cool Like Math." Very entertaining song to show kids to get them interested in math. (03:53)[more]

A third-grade teacher sings about key words and numbers. These songs help kids learn to count by numbers 2-12. These songs also help kids recognize important key words in math problems. She covers doubles, even, odd, quotient, word problems, counting... quarters, place value, etc. This is a great resource to reinforce math concepts taught in the elementary classroom. (07:31)[more]

Po-Shen Loh is a Hertz Foundation Fellow and Carnegie Mellon mathematics professor who thinks that history is a much harder subject than math. Do you agree? Well, your position on that might change before and after this video. Loh illuminates the inv...isible ladders within the world of math, and shows that it isn't about memorizing formulas—it's about processing reason and logic. (03:52)[more]

Benjamin makes numbers dance. In his day job, he's a professor of mathematics at Harvey Mudd College; in his other day job, he's a "Mathemagician," taking the stage to perform high-speed mental calculations, memorisations and other astounding mathema...tic stunts. It's part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner. (15:08)[more]

This is a student-led interview with a mathematician. The interviewing student has questions she has prepared and conducts the interview well. This would be great to show as an example of how to hold a formal one-on-one interview/discussion. NOTE:... It is lengthy, so use discretion as to which segment would be best to show. (13:22)[more]

Math puzzles and math games continue to become more and more popular. They seem very easy at first, but many people end up getting them all wrong. (06:40)
