My students have a love/hate relationship with riddles. They groan and complain that I’m asking them to do the impossible, but as soon as they solve one they beg for more. This is a good time of year for these fun puzzlers from Reader’s Digest. There are more than a few that are new to me and I plan to add to my repertoire. The one below, from Cydcor on Flickr, is a variation of a student favorite in my classroom.
