Lesson typeGrammar in Context

Final evidenceThree realistic condition–response decisions, one challenged action, one agreed backup and a focused retry

Why this lesson matters · เหตุผลที่เรียนบทนี้

For learners: The first conditional connects a realistic future possibility to a practical response, helping learners plan and agree on a backup.

For teachers: Learners move from likely-event meaning to if-clause form, response matching, American and Australian listening, and a three-situation planning task with one focused retry.

สำหรับผู้เรียน: First Conditional เชื่อมเหตุการณ์อนาคตที่มีโอกาสเกิดกับวิธีรับมือที่ใช้ได้จริง ช่วยให้ผู้เรียนวางแผนและตกลงแผนสำรอง
สำหรับครู: ผู้เรียนเริ่มจากความหมายของเหตุการณ์ที่มีโอกาสเกิด แล้วฝึกรูป if-clause จับคู่วิธีรับมือ ฟังสำเนียงอเมริกันและออสเตรเลีย และจบด้วยงานวางแผนสามสถานการณ์พร้อมแก้เฉพาะจุด

Your Goal

By the end of this lesson, you can describe three likely future situations, give a practical response to each one, and agree on one backup plan.

Why this lesson matters

A first conditional is useful when people must prepare for a realistic future possibility. The grammar becomes meaningful when the response solves a problem and another person can accept the plan.

Teacher Lesson Plan

Start with realistic likelihood and end with a shared decision. Keep conditional form attached to a practical response, reason and backup.

Stage	Teacher move	Evidence
1 · Meaning	Judge realistic possibilities.	Eight decisions
2 · Form	Build complete condition–response frames.	Six pairs + repair
3 · Order	Change information order safely.	Six rewrites
4 · Listen	Recover condition, action and reason.	Two listening maps
5 · Plan	Require three responses and a backup.	Decision notes
6 · Perform	Score MEAN/FORM/USE and retry.	Shared plan + retry

Stage 1 · Judge what is realistically possible

Choose a likely future condition before building the grammar.

4 minutes

STUDENT TASK

Situation	Likely in this context?	Practical concern
heavy rain this afternoon	yes	delivery delay
a customer calls again	yes	who will respond
the moon turns green tomorrow	no	imagined, not a real plan
the team finishes early	possible	use the extra time

Sort eight situations into likely/realistic or imagined/unrealistic.
State what evidence makes each likely situation realistic.
Choose three situations that deserve a practical response.

Finish evidenceEight likelihood decisions and three response priorities.

Teacher Help · Stage 1

Do not reduce first conditional to a formula. Learners first decide whether the speaker treats the situation as a real future possibility.

Stage 2 · Build condition and response

Use Present Simple in the if-clause and will + base verb for the planned result.

5 minutes

STUDENT TASK

Message part	Frame	Example
condition	if + subject + Present Simple	If the rain gets heavier…
practical response	subject + will + base verb	…we will use the east route.
negative condition	if + subject + do/does not + base	If the driver does not answer…
negative response	subject + will not + base	…we will not send the second van.

Build six condition–response pairs.
Change two conditions and two responses to negatives.
Repair: “If it will rain, we will cancel.”
Explain which part names the possible event and which part names the decision.

Check the future meaning

The if-clause normally uses Present Simple even though it refers to the future: “If it rains, we’ll change the route.”

Finish evidenceSix accurate pairs, four negative changes and one explained repair.

Teacher Help · Stage 2

Keep will out of the ordinary if-clause. Ask for the communicative job of each clause before correcting small form errors.

Stage 3 · Change order and keep the meaning

Lead with the condition or the response according to what the listener needs first.

5 minutes

STUDENT TASK

Condition first	Response first	Punctuation
If the bus is late, we’ll take a taxi.	We’ll take a taxi if the bus is late.	comma after the first if-clause
If Maya calls, I’ll update her.	I’ll update Maya if she calls.	usually no comma before final if-clause
If we finish early, we’ll check Plan B.	We’ll check Plan B if we finish early.	meaning stays the same

Rewrite six messages with the opposite clause order.
Add or remove commas where needed.
Choose which order works better for a warning, an answer and a decision summary.
Repair one unclear pronoun reference after changing the order.

Finish evidenceSix reordered messages, accurate punctuation and three justified order choices.

Teacher Help · Stage 3

Treat clause order as information design. Condition-first frames the risk; response-first highlights the decision or reassurance.

Stage 4 · Listen for condition, action and reason

Recover the two clauses and decide why the proposed action is practical.

5 minutes

STUDENT TASK

American English

One likely situation

Listen for the condition, practical response and supporting reason.

Australian English

Order change and shared plan

Listen for the reversed clause order and the action both speakers accept.

Pass	Record	Question
1 · Condition	the possible future event	What might happen?
2 · Response	will + action	What will they do?
3 · Reason/agreement	why it works or who accepts	Is this a shared plan?

Listen once and identify the likely situation.
Listen again and recover both clause frames.
Record the reason or evidence that makes the response practical.
Retell one message with the opposite clause order.

Finish evidenceTwo listening maps and one meaning-preserving retell.

Teacher Help · Stage 4

The clips use two accents so learners transfer the conditional meaning across voices. Replay only after they identify the missing information.

Stage 5 · Plan three responses and one backup

Prepare choices that another person can evaluate and accept.

5 minutes

STUDENT TASK

Planning move	Notes only	Evidence needed
likely situation 1	risk or opportunity	why it may happen
response 1	will + action	why this action helps
situations 2–3	two different conditions	specific practical responses
backup trigger	if the first response fails…	second workable action
agreement check	question for partner	Do we both agree?

Choose a real work, study, travel or home plan.
Prepare three likely future conditions and one response for each.
Add one backup trigger and action.
Prepare one question that asks your partner to approve or improve the plan.

Finish evidenceThree condition–response notes, one backup and one agreement check.

Teacher Help · Stage 5

Require three genuinely different conditions. A backup is not a repeated first response; it must activate if the first action cannot work.

Stage 6 · Final Practice: decide, challenge and agree

Turn likely future conditions into a shared practical plan.

6 minutes

STUDENT TASK

FINAL PRACTICE

Set the situation → propose three responses → challenge one → agree on a backup → retry

Give a 75–90 second plan with three likely future situations.
Use one accurate first conditional response for each situation.
Explain why every response is practical.
Your partner challenges one action with “What if that does not work?”
Propose one backup plan and reach a clear agreement.
Receive one target—meaning, form or real use—and retry only the weakest part.

Decision model: “If the rain gets heavier, we’ll use the east route because it stays open longer. If that route closes too, we’ll delay the delivery and call the customer.”

Score the first independent performance

MEAN · MeaningThree conditions sound like realistic future possibilities and each response follows logically.

FORM · FormThe learner controls Present Simple in the if-clause, will + base verb in the response, and both clause orders.

USE · Real useThe learner justifies the responses, handles one challenge and reaches agreement on a workable backup.

0 · Not yetThe likelihood, response or backup remains unclear.

1 · With supportThe plan works after one meaning, form or decision prompt.

2 · IndependentThree responses and one backup form a clear shared plan without a model.

Result: 0–2 Rebuild · 3–4 Developing · 5–6 B1 performance evidence.

Finish evidenceEight likelihood decisions + six condition–response pairs + six reordered messages + two listening maps + three practical responses + one agreed backup + focused retry.

Teacher Help · Stage 6

Score the first independent plan. Give one target only and record whether the retry improves realistic meaning, conditional form or collaborative decision-making.
