Playing Card Structure

Enclose a small cow, if you can.

Materials Needed

  • 26 playing cards
  • imaginary farm animal of your choice



  1. How big a fence can you build using 26 playing cards so that a cow inside the fencing could have the most room to graze?
  2. It would be a pretty tiny cow. In other words, build an enclosed area with 26 playing cards that has the biggest area inside. The cards must each be touching, if only by just a little, and they must be on their edges somehow, not just flat on the table.
