# #68 The Math Behind Pringles

##### This Math Minute was inspired by the Pringles commercial that played during Super Bowl LIII.

Thanks to Ava and Karin too for your help!

I’ve always been intrigued by the shape of Pringles, but this commercial took it to the next level and had me pondering the mathematics behind this beloved chip!

How can you spend your Math Minutes this week?

2. Watch this video on stacking Pringles in a complete circle.  If you try it yourself, make sure to record it! 🙂  Check out Cooper and Jack’s attempt!
3. A Pringles can is a cylinder that is 30 cm tall.  The circles at each end of the can have a radius of 4 cm.  Find the surface area and volume of the can.  Click here for help with the formulas.  Turn in your work to the EY Coordinator at your building.
4. Create a package that will hold a single Pringle.  Send it to yourself (or a friend) in the mail and see if your package kept it protected during its journey (didn’t cause it to break).
5. Check out this interactive Pringle stacking website! https://www.pringles.com/us/wowyoucanstackpringles.html Leave a comment with the combination you think would taste the best!

The #spadyboys had a friendly Pringle Stacking Competition/Taste Test the other night.  Check out the video!

#### parade | pəˈrād | noun

##### a public procession, especially one celebrating a special day or event and including marching bands and floats.

Who doesn’t love a good parade?  People throwing out candy from elaborately decorated floats, listening to marching bands while baton twirlers dance by, watching the line of fancy cars drive by with kings and queens waiving…the list goes on!  Have you ever participated in a parade?  What is something you remember?  When I was in 4th grade, I dressed up as one of the orphans from Annie and walked in my hometown parade.  My little sister was Annie and my older sister was Miss Hannigan.

One of my favorite holiday traditions is watching the Rose Bowl Parade on New Year’s Day.  This year marked the 130th parade in Pasadena, California.

How can you spend your Math Minutes?

• Read about the Parade here: https://tournamentofroses.com/about/ and post a “number fact” about the parade.  For example:  45.5 Million people watch the parade on television and 700,000 (estimated) watch it live. Source Feel free to post as many facts as you like.
• Create a Infographic about some of the data you found out about the parade.  Check out Violet’s example.

## Say what?

##### A student recently asked me if I knew the NATO alphabet.  I hadn’t heard of it so I told him to send me an email about it and voila…We have our #66 Math Minute Post!

Here are a few ideas on how you can spend your Math Minutes…

CM (Charlie Mike): Means continue mission.  Keep moving forward.

Thanks Alex from Swanson for this great Math Minute post idea!  I love learning new things!

# #65 What’s a smartphones made of?

##### Everyone seems to have one and my 7th grader is sure he’s the only middle schooler without one!  What is it?  A smartphone!

###### How can you spend your Math Minutes this week?
• Print off a copy of this worksheet and then click here to watch a video about what smartphones are made of.  Fill in the worksheet as you watch the video.  Turn your completed worksheet in to your EY Coordinator.
• Read about the rare earth elements on the sites linked below.  Create a Pic Collage, a Keynote presentation, or choose another app to display the information you learned.
• Create a trading card of one of the rare earth elements.

# #63: KenKen

## Can you KenKen®?

https://www.kenkenpuzzle.com/

Watch this tutorial and/or this tutorial to see how to play.  If you’d rather read the instructions, look below.  When you’re finished, print out the puzzles and try to KenKen®!  Turn in your completed puzzles to your teacher or EY Coordinator.

• The goal of KenKen® is to fill the whole grid with numbers, making sure no number is repeated in any row or column.
• If it’s a 3×3 puzzle, you only use the numbers 1-3.  If it’s a 4×4 puzzle, you only use the numbers 1-4.
• The “cages” are outlined in dark black.  The top left corner of each cage has a “target number” and a math operation (+ – x /).  The numbers you put in the cage have to make the target number.
• Sometimes a cage is one square in which case, it’s a freebie.

# #62 Aibohphobia

#### Aibohphobia: the fear of palindromes

###### What’s there to be afraid of?  Palindromes are so cool!  Whether the phobia is real or made up, palindromes are definitely real and this week we’re going to have some fun with them!

According to palindromlelist.net, a palindrome is a word, phrase, number, or other sequence of symbols or elements, whose meaning may be interpreted the same way in either forward or reverse direction (i.e. mom, wow, racecar, 10501, etc.).

Did you know that any number can be written as the sum of 3 palindromes?  It’s true!  Check out this Numberphile video.  Then, visit Christian Lawson-Perfect’s website  to try it out yourself. A computer works best for this step.  Leave a comment with the number you tried and the 3 palindromes that add up to your number.

# #61: Math Contests

### Who’s up for a contest?

Each week during the 2018-19 school year, a math contest will be posted on the EY Blog.  There are several ways to access the contests.  1. Your teacher should have a poster in his/her room with a QR code you can scan.  2. You can go to the EY Blog main page and select Math -> 2018-19 Math Contests.  3. Click here!

• Each contest will be a Google Form that you can take on your school iPad.  Although we have no way of checking, we would like for you to take no more than 20 minutes on each contest.
• Theses contests were designed for students in grades 5-6, but any student is welcome to participate.
• If there is more than one submission for any particular student, the score for that contest will not be counted.
• You MAY use a calculator, but please work by yourself!
• We will keep a running total of your contest points and award prizes periodically.

Good luck and have fun!

# #60: Millions, Billions and Trillions

by David M Schwartz is one of many picture books I have on my bookshelf.  It’s a great book to help students visualize what a million, billion, and trillion look like.  A Million Dots by Andrew Clements is another one of my favorites.  In the book, you will actually see ONE MILLION dots!  Don’t believe me?  You can count them yourself!  Check to see if you have it in your school library!

I really thought I knew everything there was to know about a million, billion and trillion until I came across this Numberphile video.  If you’re up for a challenge and making your brain stretch a little, then this Math Minute is for YOU!

Directions:

1. Print a copy (or have your teacher print you a copy) of this worksheet.
2. Follow the directions on the worksheet.  When you’re finished, turn in your completed worksheet to the EY Coordinator at your building.

###### What is your favorite kind of cookie?  Mine is chocolate chip and I especially love my mother-in-law’s recipe that has pudding in the batter.  Yum!

For this week’s Math Minute, look at the choices below and get started!

• Watch this video about one of America’s favorite cookies.  Jot down some facts as  you watch the video.  Complete this quiz afterwards.  One response per person.  Duplicate responses will be eliminated.
• Oreo Thins have a diameter of 4.5 centimeters and a thickness of 7.5 millimeters.  Write your answers to the following questions on a sheet of paper with your first and last name, school, grade, and teacher.  Have your teacher put it in the “Pony” to Sunset Hills EY.  One entry per student please.
•  What is the Circumference (C = pi * diameter) of an Oreo Thin?
• What is the Area (A = pi * radius squared) of an Oreo Thin?
• How tall would a stack of 10 Oreo Thins be?

# #58: Math Video A Day

###### Research has been conducted on the effectiveness of using video in the classroom, and according to one study by Kaltura, video is better than the written word when it comes to information retention, education, and overall experience.

I can vividly remember my 7th grade math teacher showing a video call The Case of the Missing Chick Cows : Adding Positive and Negative IntegersIn the video, the Chick Cows were disappearing all around town and farmers started to blame each other for stealing them, only to find out that at night, the Chick Cows were linking arms and flying away.  Some of the Chick Cows had left wings and others had right wings.  When they linked arms together, they were able to fly away.  Over 30 years have past since I watched that video and I still remember it.  Videos have a way of making information “stick” and we are in a day and age were we have access to a plethora of videos that can help us learn.

For this Math Minute, print off the worksheet, “A Math Minute A Day” and use a QR Code reader to scan the code for each video.  As you watch each video, jot down new and/or interesting information.  What connections can you make?  Which video did you find the most interesting?  Silly?  Entertaining?  Let us know by leaving a comment!
