Week 10: Power of Two Tag

Tag is a great way to get moving, and it isn’t just for kids. I have had my highschool groups play with just as much zeal as the 5 year olds. For this week I encourage learners to create outdoor tag games that incorporate a mathematical concept.

Here is an example using the power of 2 in tag:

  • Start of tag – 1 person is “it”
  • That person has to tag 2 people to become “not it”
  • Now two people are “it” and they must tag 2 people to become “not it”
  • The game ends when everyone is “it”

With chalk learners can draw an “it” tree to show the exponential growth of the game (1,2,4,8,16,32… or 2^0, 2^1, 2^2, 2^3, 2^4,…)
