Explanation
We use must + a base verb to say that something is necessary or a rule: You must stay on the path. We use mustn’t (must not) to say that something is not allowed: You mustn’t feed wild animals. Must has the same form for all people: I must, she must. Questions are not common for rules. We can also use have to for the same idea: You have to wear a hat. Read the rules for a nature trip: they are written for visitors and use must and mustn’t. A rule is often followed by a reason with because: You mustn’t touch the coral because it is delicate.

Listen. A guide talks to a group of children.
Look at the rules. Say what the children must or mustn’t do.
Read the book’s page 62 and make rules for an eco-tourism trip. Use must and mustn’t.
Now you. Say three rules for visitors at a park or a beach.

Rules poster. The child makes a poster with a title and five rules, three with must and two with mustn’t, and one reason with because. Then the child reads the rules to a grown-up, who says Yes or No for each one.
