Be sure to check out some of MathWorld’s Interactive Entries, updated and contributed on a daily basis. http://mathworld.wolfram.com

**Would You Rather? **Is a website maintained by John Stevens for the purpose of sharing quick and fun math challenges for students. Would You Rather? presents a picture with a mathematics problem that asks "would you rather?" Most of the questions have a financial aspect to them. One of my favorite examples is this challenge that asks "would you rather go on a 5-minute shopping spree in the store of your choice or get a $2,000 gift card to the store of your choice?" Would You Rather? offers a simple worksheet that your students can use to analyze the choices presented to them in the challenges. http://www.wouldyourathermath.com
