#82: EWeek 2021

Do some math problems and earn PRIZES!

Engineers Week (EWeek) is THIS WEEK and you can celebrate with MATHCOUNTS by solving their 5 Problems of the Day (linked below).  BONUS: Just for participating, you’ll have an opportunity to earn some prizes!

• Each day you’ll have an opportunity to solve our Problem of the Day and enter a prize drawing! You can submit your answers anytime during EWeek (Feb 21-27), so don’t panic if you get started late! Each Problem of the Day has multiple parts, and each correct answer you get will be a ticket in that day’s prize drawing.
• Everyone who participates will be entered in a prize drawing! Submit answers to at least one Problem of the Day and you’ll be entered to win, even if you don’t get correct answers.
• Each individual prize drawing winner will get a \$10 Amazon gift card and each group drawing winner will receive a \$50 gift card to the MATHCOUNTS store!

#79 Really Big Numbers

What is the biggest number you can think of?  What does that number mean?  For this math mini spark, you will be exploring some “really big numbers” and what they mean.
• In the episode, “Have You Seen This Snail?”, SpongeBob SquarePants is given a challenge of hitting a paddle ball 29,998,559,671,349 times in a row.  This causes SpongeBob to neglect Gary (his pet snail) and so Gary leaves.  Write this number out in words.

Thank you https://sites.google.com/site/pointlesslargenumberstuff/ for inspiring this this math mini spark.  It definitely sparked my curiosity!

#78 If I had a million…

In this mini spark, you will explore the length of ONE MILLION objects.  You have two options for your recording sheet:  you can either print a copy or fill out a digital version.

For inspiration, listen to How Much Is A Million by David M. Schwartz.

#75 Make Anything into Math

You know, you can think of almost anything as a math problem!

Check out this video
~Ms. Fibonacci from Math Curse https://vimeo.com/44966140

While you’re out and about over the weekend, take a snapshot of anything that reminds you of a math concept/problem.  Create a pic collage or another visual of your choice with your picture and a math problem goes along it. Create an answer key as well. Send a your problem and key to the EY teacher at your school.

#74 Fibonacci Fun

1, 1, 2, 3, 5, 8, 13, 21, 34, 55…

The Fibonacci Sequence is a simple sequence of numbers that anyone can learn!  This Math Minute has you exploring some Fibonacci Fun.

How can I spend my math minutes?
• The list above includes the first 10 terms of Fibonacci’s Sequence.  Write out the next 10, 20 (or more) terms by adding the 2 previous numbers (i.e. the next Fibonacci number is 34 + 55 which is 89).  Yes, I’m aware you can just find a website that lists out the Fibonacci numbers so all you have to do is copy them down, but instead of copying them down, practice your basic math skills and DO the math yourself!
• “Too much of the mathematics we learn in school is not effectively motivated.” ~Mathemagician Arthur Benjamin Watch his TED Video about the Magic of Fibonacci Numbers at https://youtu.be/SjSHVDfXHQ4
• Watch this Numberphile video about Random Fibonacci Numbers.  Then, try the activity he explains in the video using a coin.  My sons Toby and Trevor and I recorded ourselves doing the activity here: https://youtu.be/51K6TKbUGXk
