Session 4: Our group survival plan

Part 4. How can a group survive together?

Objectives

Today's language goal

To organise a survival plan with roles and present it, we need the words of planning (plan, route, roles, medic, scout, rules) and must, have to, mustn't, don't have to.

Warm-up

Each student writes one rule for a survival camp on a sticky note. The class groups them.

Grammar lesson: must, have to, mustn't, don't have to

To organise a survival plan with roles and present it, we need must, have to, mustn't, don't have to
For the teacher: how to run it (8 to 10 minutes)
  1. Collect the sticky-note rules from the warm-up. Read three aloud.
  2. Sort them on the board in four columns: obligation, prohibition, no obligation. Introduce must, have to, mustn't, don't have to.
  3. Insist: mustn't (forbidden) is NOT the opposite of must; don't have to (not necessary) is. Students copy.
  4. Quick check, then exercises, then the rules of the plan table.
On the board, to copy

Rule

must and have to: it is necessary. mustn't: it is forbidden. don't have to: it is not necessary, you can choose. Must often comes from the speaker; have to from a rule or a situation.

Form

  • must / mustn't + base verb: We must stay together. You mustn't open the gate.
  • have to / has to + base verb: The scout has to check the route.
  • don't / doesn't have to: You don't have to carry the map.
  • past: had to (no past of must): We had to leave at night.

Use

  • To write the group rules.
  • To give each role its mission: The medic has to ...
  • To explain what is forbidden and why.

Examples from the lesson

  • We must stay together.
  • You mustn't open the gate at night.
  • You don't have to carry the map: the scout has it.
  • The scout has to explore the route.

Common mistakes

  • Not We must to stay together., but We must stay together.
  • Not The scout have to check., but The scout has to check.
  • Not You mustn't carry the map (when you mean it is not necessary)., but You don't have to carry the map.
  • Not We musted leave., but We had to leave.

StretchProduction. Write the five rules of your group (must, have to, mustn't, don't have to), each with a reason.

Show the answers

For example: We must stay together, because a group is safer. The scout has to check the route first, because he is fast. You mustn't waste water: we have little. You don't have to carry a weapon, because the leader and the scout protect us. Nobody must leave the shelter at night, because it is too dark.

Going further (for students heading to language studies)Advanced. Use need, be required to and be not allowed to. Rewrite in a formal style.

  1. You don't have to carry the map.
  2. You mustn't open the gate.
  3. Every member must take a watch.
Show the answers

1. You needn't carry the map / There is no need to carry the map. 2. Members are not allowed to open the gate. 3. Every member is required to take a watch. Formal rules and notices prefer these forms to must.

Sentence starters

Role play

Groups of five present the plan; the class asks one question to each member.

Figures of speech in the documents

Antithesis in the plan table

Plan table: “What we must do” / “What we mustn't do”: “stay together” / “split up”; “lock and watch” / “waste water”

The plan opposes two columns, and each line opposes an action to its contrary: stay together / split up. This is an antithesis. It makes the rules easy to remember, because each good action is shown next to the dangerous one.

EntryWhich action is the opposite of “stay together”?

Show the answers

split up.

CoreWrite one more line of the table as an antithesis.

Show the answers

For example: speak softly / shout; share the map / keep secrets.

StretchWrite a group motto with an antithesis.

Show the answers

For example: Together we survive, alone we fall.

Tools to use:

Show a model answer

Our plan has three steps. First, at home, we must pack supplies, but we mustn't make noise. Then, on the route, the scout has to explore ahead, and we must stay together: we mustn't split up. Finally, at the shelter, we have to lock the doors and keep watch; you don't have to stay awake all night, because we take turns. Our motto: together we survive, alone we fall.
