Two activities to help celebrate National Donut Day
How many donuts is that = huge box of donuts to approximate.
How have donuts changed = torus volume measurements, formula intuition, and algebraic transformation of one formula into a second formula.
This activity is a investigation intended to get students and teachers to loosen up a little and appreciate how just considering a situation might lead you to a very reasonable approximation.
Too often students think that there is only one answer that is right and that the method for approaching that solution is also limited to the “correct” approach. Surely this fear of experimenting and guessing leads to math anxieties and the fear to reason and experiment.
Clock math, 1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6,7… is modular math. Let your students learn about the usefulness of modular math as they color and explore Pascal’s Triangle. Very pretty math!
Totally new activity! Let your students talk about their favorite Girl Scout cookies as they figure out what the local GS chapter really earns from these sales. Use this old graphic (where a box only costs $4.00) to figure out…

Students consider how to determine the best candy haul prediction. The math ideas of measurement error and percent error are introduced. Students then predict their own Halloween candy collections numbers and compare their predictions to their actual haul using measurement and percent error.
Monday, September 23, 2019 at 7:50 UTC (which is the same as 3:50 am EST), will be the Autumnal Equinox. It is the time of year when the imaginary plane that passes through the Earth’s Equator would also travel through the…
