Did you ever play Mad Libs as a kid? For me, it was a really fun way to pass the time on long, boring car rides. I am delighted to see that it’s also a great way to get students excited about math problems!

Previously, I blogged about a factoring version of this game (scroll down to find it). This time, I have an example that can be used for probability.

The game could be modified to be about nearly any math topic, including fractions and decimals for pre-algebra.

It’s a great way to get students to laugh and start working together. After they finish the problems they have created (at the end of the mad lib), they can do a worksheet together that you have prepared — you’ll find they are much more willing to get some work done after they have played this game!
