Spies throughout time have used coded messages to encrypt their data. Today, the boys created their own code. Working independently or in partner teams, they created a code "cheat sheet" and also a message using their made-up code.
While they were busy tinkering with language and codes, I was helping a couple at a time with navigating Ollie. At the end of the meeting, three teams competed in a relay race with Ollie. Fun times!
