The Desmos/Mathalicious happy hour in New Orleans on Friday was a great end to a long week of conferencing with math teachers, math ed professors, and the occasional vendor. My unofficial crowd estimate puts it at something like 50x the size of their 2014 event in Denver, CO.
The Desmos team and I wrote up some happy hour questions which were fun enough that several people requested the complete list. You should feel free to use them also. Please address complaints, quibbles, or corrections to Bill McCallum c/o Illustrative Math.

2. Kids Say The Darnedest Things

- … who invented the Cartesian plane, a) Albert Einstein, b) Carter Von Ludvig, c) Rene Descartes, d) Eric Cartman, e) none of the above? What percent said the correct answer? (A: 9%.)
- … to name any mathematician. Name the top four answers for one point each. (A: In order of descending popularity, Albert Einstein, my teacher, Eric Cartman, Carter Von Ludvig.)
- … which is there more of, a) feet in a mile or b) pounds in a ton? What percent said the correct answer? (A: 57%.)
- … what their favorite number was. Name the top four favorite numbers of elementary students? (A: In order of descending popularity, 7, 10, 8, 11.)
- … which would you rather have: $100 or a stack of quarters from the floor to the top of your head? Which was the winner? (A: $100. That got 67% of the vote. Did they choose well?)
- … which was heavier, a) a ton of bricks, b) a ton of feathers, or c) a ton of kittens. What percent said “kittens?” (A: 5% The winner was a ton of bricks at 93%. Good job, kids.)
- … what was faster, a) the speed of light, b) the speed of sound, c) the speed of wind, or d) the speed of kittens. What percent said “sound”? (A: 25%.)
- … if zero was a) even, b) odd, or c) neither. What was the most popular answer? (A: In order of descending popularity, Even [46%], Odd [10%], neither [44%].)
- … what the biggest number is. Name the top four most popular answers for one point each. (A: In order of descending popularity, infinity, one hundred million, one billion, googleplex.)
- … to name the shape of a stop sign. Name any of the top four most popular answers for one point each. (A: In order of descending popularity, octagon, hexagon, pentagon, hectogon.)
3. Common Critters
Even though your students may struggle to meet the Common Core State Standards, some members of the animal kingdom are doing just fine. We’re going to match a standard to an animal. You tell us if the statement is backed up by a scientific study or if we just made it up.
- Salamanders can “identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.” (A: True.)
- Ants can measure lengths indirectly and by iterating length units. (A: True.)
- Goats can prove the addition and subtraction formulas for sine, cosine, and tangent and use them to solve problems. (A: False.)
- Chickens can fluently add and subtract within 5. (A: True.)
- Octopuses can tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m. (A: False.)
- Dolphins can construct viable arguments and critique the reasoning of others. (A: False.)
- Crows can use appropriate tools strategically.(A: True.)
- Owls can count out a number of objects from 1-20. (A: False.)
- Parrots can correctly name shapes regardless of their orientations or overall size. (A: True.)
- Spiders can apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions. (A: False.)
4. Music Round
We’re going to play 10-second clips of famous songs. You need to name the number that features prominently in the song.
- “99 Problems,” Jay Z. (A: 99.)
- “22,” Taylor Swift. (A: 22.)
- “Jenny,” Tommy Tutone. (A: 8,675,309.)
- “Take Five,” Dave Brubeck. (A: 5.)
- “Summer of ’69,” Bryan Adams. (A: 69.)
- “Seasons of Love,” Cast of Rent. (A: 525,600.)

That’s so fun! It was so crowded that I found myself out in the balcony with some others the whole time so I never got to hear the trivia! Thanks for posting these and for hosting such a fun event!
AdamApril 14, 2014 - 11:41 am -
Thanks for posting these, Dan. I was going to ask for them. I hope we get a chance to do this again next year. I’m just getting my voice back.
JacquelineApril 22, 2014 - 10:31 am -
I have been to a ton of bar trivia nights, but never one centered around math! What a great idea! Does Desmos/Mathalicious host these events in other major cities? I live in upstate New York and would love to go to one!
PatrickApril 23, 2014 - 7:31 am -
I’m going to share these with my fellow math teachers today. That night was a lot of fun. Please share them next year as well since it will be a while before I get to attend the NCTM conference. Thanks

Very subtle alignment on 3.1. These guys were really on their game.
