It’s March in Dallas and the weather’s great! Maybe it’s Spring Break and you’re enjoying a day in the park with friends and family! Here’s an “edutainment” challenge for you that you can do on your own or in a team. Math educators (in school or out of school), there is more information for you here. You’ll get to visit some fun places of your choice in Dallas, you’ll enjoy quality time with friends and family, and you’ll see different places (from parks to zoos, from playgrounds to art museums) in a whole new way!! In fact, you’ll see math in a whole new way, too. And, there are prizes!!


Use the freely downloadable Otocast app to view your gameboard, consisting of 15 different math walks and over a hundred math walk stops across Dallas. You have a month to visit any number of Dallas locations you like from our list of participating sites. These walks were developed by the talkSTEM nonprofit and SMU under the walkSTEM and MathFinder initiatives with support from the National Science Foundation as well as several Dallas-based grant-giving organizations.

Here’s what you do:

  1. Just download the free OtoCast app on your iOS or Android device. Tap the badge icon within the March Mathness Challenge collection of tours to log in and begin earning badges for visiting stops.
  2. Visit a minimum of 7 stops, across any math walks in the March Mathness collection, for a chance to win $50 in gift cards each week in March and two $100 grand prizes at the end of the month. The more stops you visit and learn from each week, the higher your chances of winning (that’s math in action!).
  3. Tap a map pin to select a stop and view images, read information, or get directions. When you’ve selected a stop, press the play button to begin listening & learning!
  4. Get creative! In addition, to going on app-guided walks anywhere you choose from the above list, tag @talkingSTEM and #marchmathness in a photo or selfie of you posing a math-related question of your own at one of our stops for a second entry. Include your unique question in the caption in your post. These creative entries are eligible for more prizes!

Remember to be respectful of the spaces you’re exploring, and have fun!
