What students do
The Codebreakers Club hid a scavenger hunt in five locked notes. Turn the cipher drum and place letter tiles until each note reads.
What it adds to the lesson
Crack the Cipher breaks two notes on paper. The desk gives students a drum to turn and five notes to break, so they feel why a shift cipher falls without the key.
