Celebrating Pi Day with Dash

By Alicia C.

Play Ideas

Around and around Dash goes... in honor of Pi Day (March 14)!

What you'll need:

  • Dash
Set up Time

5 minutes


  • masking or painter’s tape to mark your starting point


How many digits of π (pi) can you recite? March 14, or 3/14, is “Pi Day,” and is a celebration of the mathematical concept π, which represents the ratio of the circumference of a circle to its diameter, which is approximately 3.14, hence the March 14 Pi Day festivities!

First, watch the video to see if you can recreate Blockly programs that train Dash to drive in different circles! Then, challenge yourself to see how many different circles you can program Dash to create!


  1. Watch the Pi Day Challenge video where Dash shows you four different circles Dash can make!

  2. Mark a spot on the floor where Dash will start creating circles. We recommend using a small piece of tape placed directly beneath Dash’s left wheel. This will be the starting point of each circle so that you can reference it to the same spot in the video.

  3. Now it’s time to program Circle A, B, C, & D using Blockly! What similarities and differences do you find between the circles?

    Hint: Try using the Set Wheel Speed block in Blockly! What kind of a program makes Dash spin in place vs. make a bigger circle with a larger radius, and what does the Wheel Speed have to do with it?

  4. How many circles can you create using Blockly and Dash? We’d love to see what you come up with! Post your videos to Facebook, Twitter, or Youtube and tag #piday #makewonder!
