Let me know if these are things that interest you as a teacher of children:

- You want the students to find your subject interesting.
- You want the students to investigate your subject in their own time, like an adult would do.
- You want the students to continue to develop their presentation skills.
- You want the students to pique the interest of the other students in the class in your subject.
- You want to expose the students in your class to a diverse set of ideas, opinions, and experiences.

When I (briefly) attended Twitter Math Camp last year, I really enjoyed the My Favorite section of the conference. This is a section where teachers came forward and presented *something* that they liked that they thought the other teachers would be interested in. These included activities, strategies, etc. Pretty much whatever the presenter thought the other teachers would enjoy. They had about 5-10 minutes to present.

To co-opt this **My Favorite** structure to my classroom, I asked every student in all of my classes to present one thing that they found interesting about math.

Here’s the document that I gave the students:

## How’d it go?

Great! I loved it, and I (think) the kids loved it. We had so many different and interesting topics. Here’s a quick subset of the topics that were covered in three of the classes:

Fibonacci and Bartok

Piles

Friendship Paradox

Volleyball winning odds

Pi Cupcakes

Vortex Math

Birthday Paradox

Chaos Theory

Hairy Ball Theorem

3D Polyhedra

Pythagorean Thm

Riot Theory

Monty Hall Paradox

Pappus of Alexandria Thm

Cryptarithms

Golf Handicap

Quad Midpoints make Parallelogram

Kaprekar’s Constant

Number Trick

4 color theorem

Diving Scoring

Brouwers fixed point theorem

P vs NP

Mole Train Woot Woot

Sound and Sine

Fourier Transforms

Photography

4D

Golden Ratio

Font Layout and Yearbook

Binary Numbers

Fermat’s Last Theorem

Rule of 72

Symmetry

Mobius Strip

Paradoxes

Nines

P vs NP

Euler

Golden Ratio and Phi

Mandelbrot Fractal

Reuleaux Polygons

Graham’s Number

Pascal’s Triangle

Tesselations

Schwarz lantern

Monty Hall

Math (and Physics) of Bowling

What’s faster, going up or going down?

Only recognize about 2/3rds of them? Me too. It was awesome seeing the different mathematics that was discussed in our classes. What was the percent of topics that lined up with any of the final exams? I’d say under 5%.

Do you have 2-5 min to spare 30 or so times per class per year with very little burden of prep on the teacher? I would bet that you do.
