Question: What would you do in the first hour of an outbreak?
Step 1
Goals
Discover the scenario and its vocabulary
Make deductions with must, might, can't
Give a short emergency announcement
Step 2
Today's language goal
To understand an emergency, guess what is happening and give instructions, we need the outbreak words (outbreak, infected, curfew, shelter, supplies, rumour), imperatives for instructions and modals of deduction (it must be serious, it can't be a joke).
Warm-up
The teacher reads a fictional radio alert: 'Stay indoors. Do not open your door.' Students list five questions they would ask.
Step 3
Read
Class rule. Everything here is fiction. We imagine, we do not frighten. Nobody has to share personal fears.
Document 1: emergency broadcast (fiction). This is an emergency message. An unknown infection is spreading across the region. The infected become violent after a bite. A curfew starts at 6 pm. Stay inside, collect water and supplies, and wait for instructions on this frequency.

Step 4
Grammar lesson: modals of deduction: must, might, can't
To understand an emergency, guess what is happening and give instructions, we need modals of deduction: must, might, can't
On the board, to copy
Rule
must be = yes, sure. might be = maybe. can't be = no, sure.
Form
modal + base verb: The radio might stop.
modal + be + adjective / noun: It must be serious.
past: modal + have + past participle: They must have closed the roads.
the opposite of must is can't, not mustn't
Examples from the lesson
The shops must be empty.
The radio might stop.
It can't be a joke: the army is on the roads.
Common mistakes
Not It must to be serious., but It must be serious.
Not It mustn't be a joke., but It can't be a joke.

Show the answers
For example: There are no cars, so the roads must be closed. The lights are off; the power might be down. A helicopter is flying low: it must be the army. Nobody is running, so the horde can't be near. The shop door is open; someone might have taken supplies.
