There are three pages of Caesar cipher challenges here in this pdf file. The first includes information on how a Caesar cipher works, and they all have messages for the kids to decipher.
Named after Julius Caesar, who apparently wrote many of his letters in code, this cipher substitutes one letter of the alphabet with another according to a rule, or "key". For example, if the key was "Right 3", if you wanted to write an E you would hop along the alphabet 3 steps to the right, and use H instead.
