One of the “wicked cool” features of the Iditarod website is its interactive map. We are becoming experts on graphic sources in our reading curriculum, so we knew right what to do to read and understand the map.

We investigated sections of the trail. Some are dangerous. Some are long. Each section has its own challenges.

We shared our favorite facts. Calooloo shared that the Yentna River can be dangerous because the water slowly moves under the ice and can overflow onto the top of the ice. Chunky Monkey was fascinated by Unalakleet, where the powerful winds off the sea can complicate the race.
We used the mileage between the checkpoints to calculate our data landmarks. Here is what we found.
Minimum: 11 miles
Maximum: 112 miles
Range: 101 miles
Mode: 48 miles
Median: 46.5 miles
Mean: 46 miles
We think the mushers have to be knowledgeable mathematicians in order to plan out their racing strategy. Math is everywhere, even the Iditarod!
