As a math appetizer for the program, here is a six-minute TED talk by mathematician Arthur Benjamin. The talk features the Fibonacci numbers, one of the two math topics for this year's program. (The other is bubbles!) https://t.co/0B2smuCAzl

There are lots of chances for teachers to work on problems collaboratively, encounter new math ideas, and grow as teachers and mathematicians in community. We also have a great lineup of guest mathematicians who will visit us and share about their work.

We are two weeks out from the start of "21st century mathematics", a program I run for K-12 math teachers. (Register now!) The program helps teachers connect the math they teach with some math that has been discovered in the 21st century. The program is flexible, free, & online.

"While everyone is glad to have a much-deserved break from the routine of early mornings and late evenings, as teachers we often end the school year thinking about the things we 'just didn’t have time to cover'." Read NCTM Pres @LatrendaK's full message: https://t.co/iWQDkSnmuW

Ten squares. The first one has perimeter 14. The second one has perimeter 22. Can anyone find ones with smaller or bigger perimeters? Or other examples that match these? Intrigued? Check out "21st century mathematics", an enrichment program for teachers: https://t.co/rR6A13M5ma

Post-its and pattern blocks are both great for exploring this problem. So is Polypad: https://t.co/sCYPdqlkRM

“The program was so well organized!!! You explained the structure in advance. The materials were readily available. [...] The problem sets were wonderful. The problems were interesting and didn’t assume a lot of background knowledge."

This is the third year of the program and I get more excited about it each time it runs. A couple of past participant quotes: "I have a much better understanding of what mathematicians do and what constitutes the subject of mathematics."
