My algebra students have been reviewing for their Algebra End-of-Course exam, and encountered an interesting problem today. It was the very LAST problem in a problem set, and we discovered it at the end of the period!

Rats! Who can I share this problem with?

Yep – I can always count on Twitter for a little fun. 😉

@mathycathy yikes I had to stare at it twice to see what was wrong… #twoplacesatonce

@fnoschese @mathycathy As it travels backwards in time, it also increases in height.That’s some interesting stuff. lolwut.com/layout/lolwut.…

@mathcurmudgeon @fnoschese @mathycathy @riazabdulla This test was clearly written for the Time Lords.

@summer_ash that’s pretty funny.. now I’m trying to imagine falling basketballs as actually traveling back in time.

@summer_ash err…opps. I guess that would be released balloons traveling forward then back in time!

I plan to share this post with my students to continue the conversation!
