How Many Students Can Fit On The Playground?

🔓 This is an unlocked sample! Byrdseed.TV is open for new memberships through October 1st, 2021. Join today!


Using Google Earth and authentic measurements, students will reach a reasonable estimate of how many students could fit on their playground.

Students will need:

  • a measuring tape or another tool for measuring
  • access to Google Earth or a similar mapping tool that can measure lengths


  1. Make guesses about how many people could fit on a four-square court.
  2. Calculate the area of a four-square court as well as how much space a student takes up.
  3. Calculate how many people really could fit on a four-square court and then test it with real kids.
  4. Calculate how many students could fit onto the entire playground using Google Earth.
  5. Extend the idea to calculate how many people could fit into other large spaces.


The registration window closes on October 1st, 2021

"I love Byrdseed.TV. It is a lifesaver"  ~  Lori in Washington

"I just subscribed to Byrdseed.TV and am loving it -- though it is kind of scary addictive in a binge-watching kind of way (that, by the way, is a compliment)."  ~  Elizabeth from Florida

"I absolutely LOVE all of the ideas on your site. I am using Byrdseed TV to differentiate activities for my clustered students to work on when the rest of the class is doing something they’ve already mastered."  ~  Wendy in Washington
