# #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

# #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

#### 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?
