With the help of decoder you can make your own code key and write secret messages!

  • Print out the decoder and cut out the circles.

  • Place the circles so that the smaller circle with letters is on top of the bigger circle with pictures.

  • Make a hole in the middle of both circles and use a paper fastener to attach the circles.

  • Make your code key by selecting a letter on the top circle and a picture on the bottom circle, for example letter ”R” and Ruby’s picture.

  • Once you have your code key in place, see which which picture represents each letter and draw your message. Let your friend decode the message by using the code key.
