Krazy Kahoot

Saturday, October 10 3:00 pm to 4:00 pm ET (online) Join MoMath’s favorite math quizmaster, Steve Sherman for a fun-filled family game bursting with a wide range of entertaining questions for ages 10 to 110. Is your family up for this lively challenge?! To fully participate in this program, you will need a smartphone, tablet, or personal computer with internet access. Please open Kahoot.it on your computer or download the app on your smart device. During the event, you will receive a PIN to access the game. Families are encouraged to work together. Krazy Kahoot is appropriate for families with children ages 10 and up — mathematically precocious children under 10 are welcome; many students under the age of 10 may find the questions challenging. This is an online-only event. Occasional video recordings are made available for a fee at videos.momath.org. In the form of a final exam, Nell brings us a touching poem conveying the beauty of mathematics and personal friendship through metaphors of lines: parallel lines, perpendiculars and transversals, and tangent lines “unraveling strings of memories.” The vivid imagery of Nell’s poem brings the humanity of mathematics of life.

They do a great job of bringing this highly technical material to life in an engaging way. Click here to watch Josie, Elisa, and Monika’s video. With Andres and Alfonso’s “Harmony Code Play” online app, users can explore the mathematical ratios in chords and scales. The judges were impressed by the clarity of the webpage’s design, its attractive interactivity, its references to math in musical pieces — and above all, how fun it is to play with and listen to. This app makes us want to play chords.

The judges appreciated the site’s clean and captivating interface that brings the user into an interactive activity of even picking an apartment in NYC!

The judges were captivated by simplicity and elegance of Sofia’s poetic imagining of a sine curve, that “refuses to choose between joy and sorrow, or between positive or negative,” the text of the poem following the curve itself.

Aria’s impressive, colorful 3D-animation of a ping-pong table stands out among the many Desmos demonstrations we have seen, using equations of curves, surfaces, and motion to create a colorful animation of a ping-pong table. The judges called it “impressive” and “clear,” noting that the orange parabolas used as decoration are helpful for communication. Click here to view Aria’s project. Camila’s “A Parabola’s Dating Profile” is witty and entertaining, slipping many important facts about parabolas into every corner of the piece. The judges praised the piece for being a clever idea and flawlessly executed, noting that all the little jokes are mathematically accurate and relevant. “Overall,” one said, “it’s engaging and delightful.” Click here to read Camila’s piece. In her poem “The Shape of an Answer,” Ceyda describes her frustration with mathematics class, where “symbols covered the board like quiet code.” Soon, though, vivid metaphors provide her a key: The sides of an equation are like two sides of a story and functions are promises; graphs are records of truth and change. One judge remarked that these beautiful tiny metaphorical expressions really do give insight to the concepts. Another wrote that Ceyda “perfectly captures the emotional journey from frustration to triumph in learning mathematics, wrapped in clever and apt metaphors,” continuing that the poem is a masterful use of words and imagery.

His lively explanation of how to collapse the terms of a telescoping series is clear and clever. One judge said it was “Delightful! Very engaging, well-explained, and creative,” and another commented on the excellent pacing of this short video. Click here to watch Jason’s video. Have you ever tried to fit a sofa through a corner in a hallway? What is the largest-area shape that can make this turn? In this hilarious video, Udip and Anthony take the viewer through the history of this problem, showing us successive refinements, up to the current state of the art — in fact, the optimal solution remains unknown. As one judge wrote, the video “nicely represents math as a journey through decades.” Another commented on the engaging narration and smooth animations. Above all
