Fido Puzzle

 

Well, it’s Friday.  Time for our fun post of the week!  Today, I confound you with the Fido Puzzle.  It’s a cute interactive site which is seemingly able to read your mind.  Follow the directions carefully, and Fido’s clairvoyant owner will be able to guess your mystery number.  It’s fun to play, and you can challenge your class to figure out the secret behind the mathematical magic!
