Flip through the slides rather quickly, checking that they remember.

Get a few strong students to help you. Give them the example script. Tell them to read out the parts. You can play one of the parts, e.g. the injured person.

Put students into groups of four or five. Tell them to write a play about someone getting hurt and/or getting helped. Roam around and make sure they understand. Help correct language errors, ideally not by telling them but by pointing out that something does not sound right and helping them figure out what it is.

Give students five minutes to pick parts, rehearse, practice saying their lines, etc.

One by one in front of the class student groups should perform their play. Boviously it's okay if they just read from the script/pass it around, whatever they need. They should act, i.e. if they are the doctor, mime checking a heartbeat with a stethoscope, so they show they understand the meaning
