Morse code worksheets
Six short messages, an A–Z chart and a separate answer key. The worksheet is one A4 page in black and white.
How to use the worksheet
- Print one worksheet per learner. Keep the answer key separate.
- Start with HI. Find the pattern for each letter in the chart.
- Move to the longer clues. A slash separates words; it is not a letter to translate.
- Ask learners to encode a two-word message for a partner. Check that a single letter's marks remain together.
- Use the Morse to English tool to check the result. A red group needs another look at its marks or spacing.

Explain the spaces first
.- is A. . - is E followed by T. . / - puts E and T in separate words. In the written exercises, one space separates letters and a slash separates words. During playback, the silent gaps have different lengths: one unit inside a letter, three between letters, seven between words.
The worksheet spells ordinary letters. The distress prosign SOS is a special continuous signal, ...---..., rather than three ordinary letters with spaces. The practice tool's SOS example spells the three letters. Do not treat this exercise as emergency instruction.
Make it a listening exercise
Use the puzzle kit for the same messages as WAV files at 15 words per minute. Let learners listen once before showing the written code. Use the speed slider in the text tool if the rhythm is too fast. There is no score or time limit.
