This Can You Crack the Code? lesson plan also includes:
The Navajo Code Talkers played an impressive role during WWII; young cryptologists research this group and practice some decoding skills of their own. Hook kids by playing the clip from National Treasure (about three minutes long), and explain that this isn't a skill only for the movies. As a group, examine the Navajo Code Talkers website, asking scholars to record a few interesting facts as you discuss this group. They discuss numeric patterns, solving a few together and then visiting a website where they see how to make a number grid cipher. Finally, they create their own code and challenge a classmate. The best part? Their code is one of the facts they learned earlier. All online resources are linked.
