I personally enjoy writing, and as a math teacher I love getting my students writing about math.
One of my favorite writing assignments for students is math-themed haiku. The rigid constraints of haiku make it an easy exercise, it allows students to access and interact with mathematical ideas in a different and creative way, and the elegance and efficiency of the for evoke the character of mathematics itself.
Here are some selections from this year’s Geometry class. Enjoy!
|We are both equal
We look exactly the same
We are congruent
Leading to certain theorems
Web of proof and math
|Three lines have congerged
Meeting at a single point
They are concurrent
Angles are dissimilar
Sides are unalike
A simple explanation
For congruent things
|Math is easy now
Calculators do all the work
Sit back and relax

Part of my presentation demonstrates simple ways that Desmos can be a part of every high school math class: Algebra, Geometry, Trigonometry, Pre-Calculus, and Calculus. While Geogebra is generally more suitable for demonstrating and exploring geometry, Desmos certainly can be useful in that course, so I wanted to show something relevant and interesting as part of my talk. I thought, “Why not compute the circumcircle for an arbitrary triangle?”
While all the pieces of the mathematical puzzle were there for me, figuring out how to put them together in Desmos was a fun, frustrating, and worthwhile challenge. I had to play around with the basic concepts associated with perpendicular bisectors and think creatively about some mathematical problems and equations. I even ended up using the new regression feature in Desmos in a clever way!
I often get caught up in little challenges like this, and this is why Desmos is so wonderful: it provides us a mathematical makerspace. It invites us to play around, to create, to engineer, to build. And all of this happens through using the language and concepts of mathematics.
Today we celebrate another Permutation Day! I call days like today permutation days because the digits of the day and month can be rearranged to form the year.
Celebrate Permutation Day by mixing things up! Try doing things in a different order today. Just remember, for some operations, order definitely matters!
