Justin LanierHi! In July I'm once again running an online program for K-12 math teachers called "21st century mathematics". Its goal is to help teachers to connect math they teach with some math that has been discovered in the 21st century.
Pass it along!

HenriA Teacher’s 12-year Journey: Marcus Elbel shares how curriculum and ideas from www.mathed.page helped improve his students’ engagement and learning.
Reaching Consensus on curricular and pedagogical matters can improve the effectiveness of a math department and improve student learning. I suggest a pathway in this post.

Peter RowlettNew #openaccess article in The Mathematical Gazette:
Optimal play in ‘Guess Who?’
Suggests using questions with an embedded paradox to produce three responses from your opponent - yes, no, or argh paradox head explodes - allowing you to narrow down the suspects more quickly.
The authors say their optimal strategy uses nothing "more advanced than induction and a recursion relation based on elementary probability... Hence Guess Who? could guide an introduction to #GameTheory to interested students through a ‘real-world’ game."

Inquiries-Week 9: Mod Multiplication
Thanks to Sam Graf for introducing me to this and suggesting some toys. Introduction Multiplication tables can be fun. Line up your numbers, multiply, and find patterns. Like with 5x5, we can fill it out and highlight symmetry, divisibility, squares, and so much more. In this inquiry, we're going to
