Olympic Medal Math Project

I read something surprising about Norway and the Winter Olympics.

With only five million people, it has won 303 winter Olympic medals, far more than any other country on the planet…
How Norway Scores So Much Olympic Gold, Wall Street Journal

That contrast grabbed my attention. I love when numbers don’t match what we expect. That’s the perfect start for a math project.

If you want, you can skip the rest and just use the finished version at Byrdseed.TV!

Four Tips for a Math Project

When I build a math project, I include four things. They help take a project from good to great:

  1. Authentic Data
  2. An Intriguing Conflict in the Data
  3. An Expert’s Perspective
  4. A Creative Product Based on the Expert

The Wall Street Journal article gives us a great conflict right away:

Suddenly, the Olympics become a giant math playground.

Authentic Data

The internet has everything we need:

Do wealthier countries win more medals? Do smaller countries sometimes outperform everyone?

Curriculum Connections

You can use this data in lots of ways, depending on your students’ ability.

Younger students can:

Older students can:

And everyone should be asking:

What do these numbers reveal?

A bonus idea: students can use spreadsheets to do the calculations and graphing. That shifts the work away from tedious arithmetic and toward real analysis.

Expert Perspective

This is really a statistics project.

Students can take on the role of statisticians, looking for hidden patterns in the data.

A statistician’s main tool is simple:

The final product could be a set of graphs plus a short written response:

What patterns did you uncover?

Graphing Samples

Here are a few examples to get started.

Total Medals vs. Population

Country Name Total Medals Population (millions)
Great Britain 802 63
France 765 66
Norway 451 5
Japan 435 127
Canada 423 35
South Korea 288 50
Austria 287 9
Brazil 108 220
New Zealand 100 5

This scatterplot compares total Olympic medals vs. population in millions using nine countries.

The fun part is what shows up once the data is graphed:

Graphing makes these patterns visible.

Winter vs. Summer

Country Name Winter Medals Summer Medals
Great Britain 22 780
France 94 671
Japan 37 398
Canada 145 278
South Korea 45 243
Norway 303 148
Brazil 0 108
New Zealand 1 99
Austria 201 86

I also graphed summer vs. winter totals and overlaid a rough “temperature gradient” to show each country’s seasonal dominance:

summer v winter

Some quick takeaways:

Ratios

Older students can go one step further and calculate something like:

medals per million people

Country Name Ratio (medals per million)
Great Britain 12.8
France 11.6
Norway 90.2
Japan 3.4
Canada 12.1
South Korea 5.8
Austria 31.9
Brazil 0.5
New Zealand 20.0

Some observations:

And yes—these ratios are worth graphing too.

On Choosing Countries

It’s fun to let students choose their own countries (ten or fewer works well).

Just be careful with huge countries like the US, China, or India. Their numbers can overwhelm the scale of the graph.

Unless, of course, that’s the lesson!
