#70 Algebra in Pictures

Images to create this puzzle taken from pdclipart.org

One of the things I struggled with when taking Algebra was the use of letters (variables) to represent numbers.  However, if we remove the letters and replace them with pictures, somehow Algebra becomes a little more manageable.

How can I spend my Math Minutes?

  1. Figure out the picture puzzle above stating what the ? represents in the final “equation”.  On a piece of paper, put your answer along with your first and last name, grade, school, and classroom teacher.  Give it to your EY Coordinator (or tell your classroom teacher to “pony” it to EY at Sunset Hills).
  2. Create your own picture puzzle.  I used Keynote, but you could use Explain Everything, Pic Collage, or another iPad app.  Pictures for your puzzle can be found at https://www.pdclipart.org/ These puzzles can be emailed to Dr. Spady (ask your EY Coordinator or classroom teacher for the correct email).
  3. Figure out the 11 puzzles pictured below.  On a piece of paper, put your answers along with your first and last name, grade, school, and classroom teacher.  Give it to your EY Coordinator (or tell your classroom teacher to “pony” it to EY at Sunset Hills).

Thank you Mrs. Bridwell for the inspiration to create this post!  Thank you to Mrs. Bridwell’s 6th graders for all the great puzzles below!

#69: Snowiest February

Who knew SNOWIEST was even a word?!

Was February 2019 the SNOWIEST of all time?

How can I spend my Math Minutes?
  1. Create 1, 2, or 3 different graphs to display the data above.  For a clearer image of the data, click here.   Use the Create-A-Graph website to make a graph of the data.  Be sure to include a title and label your axes.
    • Top 5 Snowiest Februarys
    • The Top 5 Snowiest Winter Seasons (Dec-Jan-Feb)
    • Top 5 Snowiest Winters (Jul 1- Jun 20).
  2. Take a look at the graphs in the image below.  For a clearer image of the graphs, click here.  The information in the blue box is particularly helpful in reading the graphs.  Answer any of the following questions by leaving a comment and/or leave a question for someone else to answer.
    • How many times in January/February 2019 did the temperature range fall mainly in the record highs?  What about the record lows?
    • On how many dates was the temperature range very small (short blue bar)?
    • How many times did the temperature range fall in the average section (green)?
    • What do you find interesting about these graphs?

 

 

 

#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?

  1. Read about the Geometry of Pringles by visiting this website: https://interestingengineering.com/geometry-of-pringles-crunchy-hyperbolic-paraboloid Post a comment about something new you learned.  Make sure to include your first name only, grade, and school (i.e. Ava, 6, Loveland).
  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!

#67 Rose Bowl Parade

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.
  • Read about the Design and Manufacturing process for floats.  Leave a comment with something new you learned and/or your idea for a float.

#66 Alpha Bravo Charlie

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!

#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.

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.
