# For Teachers: #TMC18 Morning Session Wrap-Up & Reflections

I want to reflect publicly on the amazing experience that was #TMC18.  This was my third Twitter Math Camp, and I get more out of the experience every time I attend.  I am grateful to Dave Sabol, St. Ignatius High School, Lisa Henry, and the entire TMC planning committee for their hard work and dedication.  Thank you all.

# For Teachers: Pythagorean Project

My students just completed a project on The Pythagorean Theorem, and I wanted to show some awesome work they did.

# For Teachers: Teaching The Algebraic Properties Through Writing

The single worst lecture/lesson I have ever given was when I introduced the Algebraic Properties to students.  Mind-numbing, boring, sleep-inducing…and that was just me!  The students must have been feeling it even worse.

# For Teachers: Soda Can Enigma Machines

Caffeinated AND mysterious!

This week in my Advanced Pre-Algebra classes, we learned about The German Enigma Machine and Alan Turing’s efforts in WW2 to break the Enigma code.

# Random Seating Chart w/Excel

I’ve had some requests from the #MTBoS community to talk about my Random Seat Generator I’m using this year.  Here ya go:

# Room Tour 2016/2017

I report back for inservice tomorrow, and the students come back next week.  This begins year 18 of my teaching career, year 15 at my current school (and in my current classroom).

# TMC16 Reflections

So I’ve been putting this off for a while.  But I’ve had good reasons.  Well…at least one good reason.

# For Teachers: Please Don’t Teach Exponent Rules

Let’s take a look at three monomials (terms) that one might be expected to be able to simplify in a Pre-Algebra or Algebra 1 class:

If you were discussing traditional exponent rules as you might find in a math textbook, how would you approach these problems?  I’ve put a hypothetical conversation below.
