A couple of years ago, I was impressed with Dan Meyer and Dave Major's creation of Boat Race, an activity that involved navigating around buoys with some knowledge of bearings. I hoped to use his creation for my ninth graders two years ago, but Boat Race in its original form was zapped from the interwebs. At the time, I did an analog version, which you can find here in PDF form:
This year, when looking at my materials in the revamped Math 9 course, I felt compelled to take a crack at my own digitization of this activity. Here's the result:
You can also visit the live site here and try it out yourself.
The moving circle moves painfully slow by design. Students will (hopefully) be compelled to do a good job of calculating distances and angles accurately. I plan to give them the analog version on paper for planning purposes. Shortest time by the end of the class wins fame and glory.
