#30 Math Minute: What day of the week is it?

Screen Shot 2017-01-10 at 11.34.09 PM

I found this very complex mathematical formula that allows one to figure out the day of the week any date falls on.  Don’t let the formula intimidate you!  I did this with some 3rd graders today and with a few explanations, they were able to figure it out.  So can you!

Click here for a quick tutorial on how to use the formula

How can you spend your Math Minutes this week?

  • Watch the video linked above
  • Figure out the day of the week you were born on using your birthdate and year.
  • Figure out the day of the week for another date in history (Pearl Harbor, Declaration of Independence, etc.).
  • Check out this Dr. Math Forum post for some more information about calendars and even a different formula to use

#29 Math Minute: Fractals

According for, A fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. Driven by recursion, fractals are images of dynamic systems – the pictures of Chaos.

#24 Math Minute: The Art of Math

Math concepts are fantastically weaved into all kinds of artwork and Cloud Gate in Chicago, IL is no exception!  Cloud Gate is British artist Anish Kapoor‘s first public outdoor work installed in the United States.

According to the city of Chicago website,

The 110-ton elliptical sculpture is forged of a seamless series of highly polished stainless steel plates, which reflect Chicago’s famous skyline and the clouds above. A 12-foot-high arch provides a “gate” to the concave chamber beneath the sculpture, inviting visitors to touch its mirror-like surface and see their image reflected back from a variety of perspectives.

Inspired by liquid mercury, the sculpture is among the largest of its kind in the world, measuring 66-feet long by 33-feet high.  Listen to the audio tour below.

#23 Math Minute: A Yummy Graph!

infographic |ˌinfōˈɡrafik|

a visual image such as a chart or diagram used to represent information or data. a good infographic is worth a thousand words.

I went out to lunch recently with my family and noticed an eye-caching infographic at the center of each table.  I wish I could post a picture of it, but that would ruin the surprise!

Below you will find the data from the infographic.  Your job is to create a picture that displays all the information.  The only requirement is that all the information below is somewhere on your 8 1/2 x 11 page.  Use colors, crayons, pencils…whatever!  Get creative!  Don’t know what an infographic is?  No problem!  Take a look at some of these examples.

Data that must be included on your infographic…

  • 39,598,080 mini gingerbread muffins devoured last year from this salad bar
  • 1980 was when this restaurant introduced a salad bar.  It was based on the suggestion of a radio salesperson.
  • 10,000,000+ salad bars were ordered at this restaurant in 2015
  • The original salad bar at this restaurant offered 9 ingredients.  Now there are 50+ ingredients and they include select USDA-certified organics.
  • There are 1,906,884 possible combinations for a 5-ingredient salad with a base of lettuce.
  • If you had 1 salad a day, it would take 5,224 years before repeating a salad combination.
  • No MSG since 2008 and everything on the salad bar is trans-fat free.

Make sure your first and last name, teacher’s name, and school are on the back of your page.  Give your completed infographic to the EY coordinator at your building.  We will post some examples on the blog and the winner will receive a free salad bar from the restaurant!

#21 Math Minute: Names of Polygons

Screen Shot 2016-04-30 at 4.34.11 PM

While teaching an enrichment lesson to 3rd graders a few weeks ago, one of them asked what a 13-sided figure was called.  It was a great opportunity to do some research together.  We found a few great resources which I’m now sharing as this week’s Math Minute!

How can I spend my Math Minutes this week?

  • Watch The Greedy Triangle by Marilyn Burns  Reading this book aloud is my  favorite ways to start a geometry unit.  After watching the video, post a comment about your favorite shape and where it appears most often.
  • Pick a polygon and draw 4-5 pictures of where that shape appears.  Turn in your drawing to the EY Coordinator at your building.
  • This website: was where the 3rd graders and I found the answer to our 13-sided polygon question.  Take a look at the different naming conventions for polygons on this site and post a comment with a few new names you discovered.  Take it a step further and draw your polygon.  Remember that a polygon is a closed figure made up of straight lines.
  • Create a “Geometry Around Us Presentation.”  Look at this example: as a starting point.  You can use any tool (Explain Everything, Pic Collage, Keynote, etc.) and include as many vocabulary words as you like.  Try to find pictures of polygons in your school or outside.
  • Write your name in block polygon letters.  Color the letters and under each one, write the correct name for each polygon.  Turn in your drawing to the EY Coordinator at your building.
