# #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

*The Fibonacci Sequence*

## 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! Watch his TED Video about the Magic of Fibonacci Numbers at https://youtu.be/SjSHVDfXHQ4**“Too much of the mathematics we learn in school is not effectively motivated.” ~Mathemagician Arthur Benjamin**- 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

# #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.

- 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** - 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).

# #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?**

- 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).
- 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** - 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.
- 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).
- 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.
