"Stumped" is a Laws of Exponents game where two students attempt to "stump" each other by taking simple pieces of a potential exponential expression and adding enough exponents, parentheses, and mathematics operations that it might keep their playing competitor from being able to simplify it. Students love the challenge of not allowing their classmate to give them something they can't solve. They really have no idea that it's making them REALLY good at simplifying exponents along the way. See the preview for an example of how you play the game.
This product is also included in my Laws of Exponents Personalized Learning Unit, which is so good Santa put it on the Nice List twice.
