The worst birthday party ever

Scan for the app

Inversion means flipping a problem upside down. To plan the best party, first plan the worst!

  1. List ways to make a party terrible.
  2. Flip each one into a way to make it great.
Example: Worst: invite nobody. Flip it: send invites a week early.

Extend it: Use inversion on a school morning: what makes it the worst? Then flip it.

My brain felt: ☐ easy ☐ just right ☐ stretchy
