### The Schedule Makers

I always assumed Major League Baseball’s schedule was constructed using some intense algorithm. It seems that for twenty-five years MLB used human intuition to construct their elaborate schedule. It seems like now programming and computer programming sophistication has caught up.

This is a worthwhile twelve minute video by ESPN’s 30 for 30 series (directed by Joseph Garner). Also a worthwhile graph theory application.

### Hashtag Math

Posted on

Last year as a test review, I asked my students to categorize problems.  Beyond knowing the mechanics, I want my students to know the when and why. Thus I asked them to tell me what “big theme” each problem represented.  With a set of review problems, I began to #hashtag the problems. Two examples are shown below:

I have no scientific research showing that this helps my students make connections and categorize concepts, but they certainly remembered and enjoyed hashtagging math problems!  This is a technique I plan on continuing and is worth considering beyond just review.  At minimum, hashtagging in class was unique, so it stood out as something special.  Their favorite was #factoredform, so I wonder how long until its trending?

### An Election: Heads vs. Tails

Posted on

Yesterday during a tangent in my Algebra 2 class I realized how little understanding my students had about the voting process as well as how predictions are made and how, when, and why networks announce winners without all of the votes counted.

Today, I ran an activity that pitted Heads vs. Tails. Each student received a penny and flipped the coin to determine their vote: Heads or Tails.  The class consisted of 19 students.

In our first election, we strictly counted votes- a popular election.  Tails beat heads 10-9.
