How many gumballs are there?

Gumball Machine Problem from Brian Marks on Vimeo

This problem is a little puzzle to get your students thinking, estimating, and calculating. We've given you a pdf file with only a picture of the gumball machine to use for estimating.
  • How many gumballs are there?
  • At $0.25 per ball, how much will it cost me to buy them all?
  • How long will buying them all take?


For Adventurer members we have our thoughts on how a student might estimate or calculate this quantity.
