CRACK THE CODE is a fun way to experience what archaeologists or linguists go through as they attempt to decipher and decode unknown languages of the past. Like a cryptogram, have students use the letter frequency chart and the common tendencies of the English language, to crack the code and decipher this very important message! I like to use this for my history class to help students understand the difficulties that historians face in discovering an unknown language. You could also use it as a brain break or a fun filler for any class. Regardless of the use, it’s a fun challenge for students to do individually or as a group competition. Enjoy, and thanks for checking out the resources at Mister Harms! Have an awesome day!

What’s Included:

- A coded message from an unknown language
