Try an example

Introduce a short key, for example circle = C, square = A and triangle = T. Circle–square–triangle spells CAT. Then find a known symbol in another word and keep its letter unchanged.

What to check

Begin with words the participant can read once decoded. Solve one example together and leave another for practice. Distinguish the challenge of reading from the challenge of identifying a substitution.

Use patterns and test guesses

Look for repeated letters within words and short words that fit the sentence. A frequent letter is a clue, not a certainty. Keep a symbol–letter table and remove a guess if it creates a contradiction elsewhere in the text.
