Where is your favorite place to eat pizza?  My Top 3 are Sortinos, Mama’s Pizza, and Papa Johns.  Of course whenever we eat pizza as a family, we have to make up some math problems!  Explore some “pizza math” by completing the activities below. 

How can you spend your Math Minutes?

  1. Calculate the area, circumference, and price per square inch of the next pizza you order.  Make a display of the math/calculations.  Compare it to a pizza from another location.
  2. Watch the videos at: https://youtu.be/WdmlODxZm1w and  http://www.popularmechanics.com/science/a22162/pizza-math/ and post a comment about something new you learned.
  3. Play Papa’s Pizzeria at: http://www.coolmath-games.com/0-papas-pizzeria or play Tony Fraction’s Pizza Shop at: http://mrnussbaum.com/tonyfraction/
  4. Read about how to cut a better slice of pizza with math at:  http://www.popsci.com/cut-better-slice-pizza-with-math and post a comment about something new you learned.
  5. Play Pizza Fractions at: http://math.rice.edu/~lanius/fractions/
Have a yummy time exploring pizza math!

#32 Math Minute: Narcissistic Numbers

According to Wikipedia, a narcissistic number is…

In recreational number theory, a narcissistic number (also known as a pluperfect digital invariant (PPDI), an Armstrong number (after Michael F. Armstrong) or a plus perfect number) is a number that is the sum of its own digits each raised to the power of the number of digits.2000px-Confused.svgHUH?!

Narcissistic Numbers aren’t actually that confusing if you know how to do a couple things.  Here’s how you can spend your Math Minutes so that you can learn more about these peculiar numbers!

  • Watch this video by Numberphile: https://youtu.be/4aMtJ-V26Z4
  • Look at the list of Narcissistic Numbers on Wolfram Alpha:  http://mathworld.wolfram.com/NarcissisticNumber.html
  • Pick a Narcissistic Number to “work out” on paper to prove it works.  See example below.

#31 Math Minute: Super Bowl Math

Super Bowl LI happened on Sunday, February 5.  Whether you’re a football fan or not, it’s interesting to look at the event’s history.  This Math Minute post has you predicting, collecting, and displaying some data related to the Super Bowl.

How can you spend your Math Minutes?

  • Make some predictions.  Without looking online for the answers, predict how much a 30 second ad cost to run during the Super Bowl in the following years:  1967, 1977, 1987, 1997, 2007, 2017.  Record these predictions on a sheet of paper.  Next to your predictions, use this site to record the actual cost for those years.
  • Create a pictograph.  Pick 5 NFL teams and write those on the x-axis of your graph.  Using this site, record how many Super Bowls each team played in.  Use a helmet, a football, or some other picture to display the data.  Make sure to include a key for your graph (i.e. 1 football = 1 Super Bowl).  Give your completed graph to the EY coordinator at your building and we may showcase it on the EY blog!
  • Create a scatter plot of the data on this site.  Use the x-axis to represent the year and the y-axis to represent the cost of a 30 second ad.  There are several tools you can use to make your graph including Numbers (app on the iPad), Create A Graph website, Scatter Plot Tool, and others.  Share your completed graph with the EY Coordinator at your building.
  • Choose any other data related to the Super Bowl to analyze.  Some ideas include ages of players, points scored, salaries of players, etc.  This article talks about the data, analytics, and probabilities associated with the Super Bowl.

Have Fun!

I found this very complex mathematical formula that allows one to figure out the day of the week any date falls on.  Don’t let the formula intimidate you!  I did this with some 3rd graders today and with a few explanations, they were able to figure it out.  So can you!

Click here for a quick tutorial on how to use the formula

How can you spend your Math Minutes this week?

  • Watch the video linked above
  • Figure out the day of the week you were born on using your birthdate and year.
  • Figure out the day of the week for another date in history (Pearl Harbor, Declaration of Independence, etc.).
  • Check out this Dr. Math Forum post for some more information about calendars and even a different formula to use

Turn in all LEGIBLE work to the EY coordinator at your building for a small prize!

According for fractalfoundation.org, A fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. Driven by recursion, fractals are images of dynamic systems – the pictures of Chaos.
