The 2014 Winter Olympics have concluded. Which country had the most successful olympics? Three students can't agree. Have your students jump into this conflict and work with data and ratios, fractions or percents as they decide which country had the most successful olympics.

Extension: I was thinking about what it must feel like to be an athlete coming home from the Olympics without a medal. Surely most of the Olympians come home without medals. What are some of the numbers? Calculate the percentages. Talk about the odds per country.

We’ve gathered data for your class to use while engaging in this conversation. Athletes should be proud to have competed but the medal hype might be discouraging.

Use our data and engage your students in some math to help get perspective.
