Students work in small groups to find fascinating facts about the Summer Olympic Games and Olympic history. This is not really a math activity, but it might be great to use as a launch or to share with another teacher on your team.

The link may not work, but it just linked to a lesson plan that is described here. Students choose a sport, research it on the Internet, and create a graph.
Olympic Records
Give the students 10 graphs showing how Olympic records have changed over time, and ask them to determine which sports they represent.
Here are some questions to consider, which may help you to make sense of the graphs:
Can you determine what the units might be on the vertical axis for each graph?
Why do some graphs show a decreasing trend and some an increasing trend?
Are there any unusual features on any of the graphs? Can you think of a plausible explanation for them?
A History of World Records
Interactive graphs from the New York Times
How Badly Would Usain Bolt Destroy the Best Sprinter of 1896?
Animated interactives comparing the gold medal finishing times or distances in several sports. Not part of a lesson plan, but might be a cool engage activity.

At the Olympics, the blink of an eye can be all that separates the gold medalist from the 10th-place finisher. In some events, this is obvious. But in others, with athletes racing one by one, the closeness of the race is harder to perceive. Listen to the differences in this lesson from the New York Times.

Track a Sport
Students track the results of various sports during the Olympic games and report on the results. This lesson plan is for language arts, but this could easily be adapted for math. Instead of writing a news report, students can create a graph.

Mini-Metric Olympics
Students will become familiar with metric units by estimating and measuring in a "Metric Olympic" setting. Look at the preview for ideas.
AIMS lesson. Not viewable now.
Olympic Records Through Time
Are we faster, stronger, better than we used to be? Compare the records of gold medal Olympic winners for the last 100 years and decide. Produce a graph/chart which shows performance in a particular event over time. If possible, find an equation which describes the trend in performance. Write/discuss the possible causes for the change.

Science of the Winter Olympic Games
From NBCLearn and the Silicon Valley Education Foundation. The site breaks the lesson into grades 5-8 and 9-12. Although the title says science, there are several math lessons, including the following:
Olympic Metric Conversions
The Internal Athlete: Cross Country Skiing
The science lessons also have a strong math component and sound like they would be great for an interdisciplinary project.
Winter Olympic Math from Scholastic
These lessons are geared toward elementary, but they could be modified for middle school.
Countdown to the Winter Olympics from Education World
Winter Games Lesson Plans from the Australian Olympic Committee
Another site geared toward elementary, but adaptable for middle school.
