Give the session one aim
Choose a narrow goal: recognising the table areas, explaining a sample turn, or reading a score entry. Tell everyone that the first practice is for asking questions. Avoid turning it into a test of who can remember the most details.
Keep one reference open
Use a complete rules source, with a bookmark at the section you are learning. Ask one person to read and another to explain it in their own words. When the explanation is uncertain, return to the passage together instead of voting on what sounds familiar.
Use visible cards
For a teaching exercise, lay the sample cards where everyone can see them. Stop after each decision and ask what information the learner needs next. These pauses are a practice technique, not a change to the rules of a regular game.
End with a useful note
Write down one resolved question and one question to revisit. A short, accurate record is easier to reuse than a long list of guesses. Send the beginner route to the group so everyone can find the same starting point.
