Big bucks

Mike Trout just signed a huge contract.  He'll be receiving $430 million dollars playing for 12 years with the Los Angeles Angels.  Let's take a look at some of the other big world sports' contracts from the NBA, NHL, NFL, MLB and European Football (what Americans call soccer).  We often hear about big player contracts. Who makes the most per year? Per game? What sports?

In this activity, with a twist on unit rate, students find the average pay per year or "unit rate of pay" for a collection of highly paid athletes. Students think about unit rate; proportionality; slope; the relationship between multiplication and division; and the contrast between the pay of various sports.

Does seeding really matter?

March Madness is the big 68 team college basketball tournament that takes over our TV viewing during the weekends of March. School and office friends are filling out brackets.  Engage your students in percents as they get excited about March Madness. Is getting a higher seed really an advantage?  Use 30 years of data to help determine for which seeds it makes sense to pick an upset.  Finally, students determine a general strategy for picking games in the first round.

Sunday, March 17th, is Selection Sunday for the Men's March Madness Tournament.  Monday night, March 18th is the selection night for the Women's March Madness Tournament.  The March Madness bracket predictions can begin.

What are your chances of picking every game? How does the change from 64 to 65 to now, 68 teams in the field complicate things?  How many brackets would you need to fill out to pick every possibility?  How many reams of paper would you need to print all of those brackets?  Let’s do the math!   Also, check out the video below that explores your odds of picking all games in the tournament perfectly.

April just had a new baby!

Saturday, March 16, 2019.  April went into labor at about 11:00am and birthed a new baby giraffe at about 12 noon.

Here are two past Giraffe baby activities for today!

Huge Key Lime pie

More for π Day!

On a cold and snowy day in Boston, two chefs created a huge Key Lime pie to remind the frozen people of the Northeast how tasty and warm the Keys of Florida are.

After you show this movie to your students, ask them what they wonder about this huge pie and what they would like to figure out.

Supposedly the huge pie served 1,000 commuters but our figuring suggests something else. This is a Yummy activity about multiples, proportions, volume, reasoning and π.
