Teacher-created worksheet


Write a simple phrase about getting a special treat (i.e. extra recess or something sweet) on the board in Navajo. Ask students what they think it says and what language it is written in.

Teach them about the Navajo code talkers who were recruited by the Marines during World War II. Pass out the worksheet and practice looking up words or letters. Have the students work in pairs to decipher the phrase on the board.

Have students make up their own sentence using the Navajo code and then have them ask a neighbor to translate the sentence.

Wrap Up:

Talk to the students about their experience. Was it like being a secret agent? How would they go about developing their own secret code? How would they use it in their daily lives?
