Morse Code Worksheet
Also available as an Adobe PDF file.

Every letter or symbol that you can use to write a message has a code written in dots and dashes that can be used when writing or speaking may not be practical. This code can be sent audibly or visually. With practice it is possible to send and receive Morse code at very fast speeds.

For this exercise it is not necessary to memorize all the letters and symbols used in Morse code, but to understand how they are used. This worksheet is designed to help you understand how to send and receive Morse code. If you want to learn Morse code and be proficient in it's use try visiting TerraX.org's web site at http://TerraX.org and playing the Morse code game.

Part One

Instructions:

To fill in the blanks below use the following words: Morse code, space, dot, dash, static, and full stop.

  1. ________________The length of one of these is equal to the length of a dot.
  2. ________________This can make voice messages, sent over a radio, hard to understand.
  3. ________________A system of "dots" and "dashes" used to communicate when voice or other systems cannot be used.
  4. ________________The length of this sound is three times as long as the length of a dot.
  5. ________________This is used to mean the end of an idea. It can also be used instead of a period.
  6. ________________The length of this sound is short, three times it's length makes a dash.

    Part Two

    Instructions:

    Use the table of Morse code translations to fill in either the dots and dashes or the letters that are missing from the problems below. Example: The correct Morse code translation for Cat is -.-. .- -

    Word(s) Morse Code   Word(s) Morse Code
    Cat -.-. .- -     ... - --- .--.
      .... .- -   Dart  
    Buzz     Full stop

    1.
    Wave       -..-   .-. .- -.--

    Part Three

    Instructions:

    Match the messages with the Morse code. Write the letter of the matching code on the blank by the message that it is. Example: The Morse code translation of 1 is e.
