The first talk in the Mathigon Guest Speaker series was last week. Dr. James Tanton shared 12 proofs that 2 = 1. It was a joy-filled and engaging session. Watch the talk at https://www.youtube.com/watch?v=JbbU4GgpXLk. I think you'll find it worth your time! Sign up for future events in the Guest Speaker Series at mathigon.org/events.

Working on adding fractions with students? Consider using this lesson on Egyptian Fractions! https://mathigon.org/task/egyptian-fractions
In this version of Bingo, using different sided dice can motivate students to discuss the sample space and probabilities of the different numbers that can be rolled. https://mathigon.org/task/bingo
Easily changing the scale of the numbers lines on Polypad can help students create a visual model of multiplying decimals. Learn more here: https://mathigon.org/task/decimal-multiplication
Using the Algebra Tiles on Polypad can help students make sense of and visualize what it means to "Complete the Square." https://mathigon.org/task/completing-the-square
In the game "Cover Up," students try to be the first one to make 1 whole. Learn more about the game here: https://mathigon.org/task/cover-up.

High SchoolDo you know this ancient legend:
"According to legend, the city of Delos in ancient Greece was once faced with a terrible plague. An oracle told them that this was a punishment from the Gods, and the plague would go away if they built a new temple that was exactly twice the volume of the existing one. The Delians doubled the edges of the temple, but the plague did not stop. What went wrong?"
