Well, mentally it wasn’t a hard thing to wrap heads around, but the question of “why?” came up a lot…to that I didn’t have a good answer.

We did a transformation activity in class today. It went well. While they were doing that, I wrote on the board. Before I tell you what I wrote, you have to know (to make it funny, or meaningful if not funny) that my pass is a small plastic elephant. Other teachers have wooden arrows, steering wheels, etc. I have a small plastic elephant. I wrote “If you don’t have my pass, your absence from class is irr-elephant.” Three people laughed. One of them was the same as the one who got the “only 3 times” yesterday. 3 down, 103 to go. I did have a girl leave my class today. So while I didn’t necessarily make any connections, I did up the percentage of the students to which I have. 102 to go!

TWENTY NINE is the only number which is written (in all capitals, and without the hyphen) with as many strokes as its value. Try it , I did!

Also: play on a calculator. If you start with any row, column or diagonal, and type it forward and backward to get a 6-digit number (123321, 456654, 789987, 159951, etc…) they are ALL evenly divisible by 37.

29th…what’s special about 29? It’s part of a Pythagorean triple? Nah, that’s not interesting enough. Prime? Eh, there’s infinite primes. The strokes-value thing is interesting, but they’ll be too much arguing “but I cross my I,” or “What about the hyphen?” or trivial stuff like that which will take more than the 2 minutes that I want this to take. Sum of 3 consecutive squares! 2^2 + 3^2 + 4^2 = 4 + 9 + 16. Maybe I’ll go with that. In Tarot, 29 is represented by the 3 of Wands. It infers spiritual power, introspection, reflection and receptivity. Sweet! We’re doing transformations in Algebra 2 — reflection? Boo-yah. There it is. Goodnight

## About Mr. T

Well, I'm interested in math. Teaching it, learning it, describing it, living it. Creating it. Most importantly (to me) is helping others appreciate it as much as I do.
