Junior English: Conditionals Tutor Prep Guide | Zero, First and Second Conditional Pairs

2026-11-12

Tutor lesson-prep guides · Junior Secondary English

Students see if and reach for will, so If I were you, I will go appears every year. The problem is not a forgotten rule but three conditionals collapsed into one. This lesson builds a single table pairing the if clause with the main clause, then locks it with three contrast sets.

Objectives — Students can: (1) state the tense pair for each of the three conditionals and choose correctly in rewriting tasks; (2) use were instead of was in the second conditional and explain that it marks a present unreal situation; (3) rewrite between unless and if clauses without changing the meaning.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Present simple	What happens to a third person singular verb?	Add s or es, and use does in questions and negatives
Future with will	Which verb form follows will?	The base form
Clause order	What changes when the if clause comes first?	A comma follows it; at the end no comma is needed

02 Lesson flow (60 minutes)

Time	Stage	Tutor does	Student does
0-6 min	Two opening sentences	Say the same thing twice, once real and once imagined	Write an answer now, compare at the end
6-20 min	Zero conditional	Present simple in both halves for general truths	Write three everyday rules
20-34 min	First conditional	Present simple in the if clause, will in the main clause	Turn the rules into predictions
34-46 min	Second conditional	Past simple in the if clause, would in the main clause, were for be	Turn the predictions into hypotheses
46-56 min	Unless and rewriting	Unless equals if not, clauses can swap places	Rewrite two sentences each way
56-60 min	Exit check	Collect two questions, mark at once	Complete independently

03 Teaching script (read it out)

Scene 1: Zero conditional: same tense in both halves, for facts

The test is whether it happens every time, so both halves take the present simple. Example: If you heat ice, it melts, with no exception, so both verbs stay in the present. Separate a rule from a single event: rules take the zero conditional, one-off events take the first. Once that line is clear, the other two cannot blur together. Mention the when variant: when carries no hypothesis, so it sounds more certain.

Students do: write three school or daily rules in the zero conditional and check that both tenses match.

Scene 2: First conditional: present simple plus will

The first conditional describes a real future possibility, so the rule is one sentence: present simple in the if clause, will plus base verb in the main clause. Example: If it rains tomorrow, we will cancel the picnic. The commonest error is putting will inside the if clause, which always loses a mark. Fix the order with a chant: no will inside the if clause, will lives in the main clause only. Then swap the clauses: no comma when the main clause leads, a comma when the if clause leads, and students drop that comma every time.

Students do: turn the three zero conditional rules into predictions about tomorrow using the first conditional.

Scene 3: Second conditional: past simple plus would, and were for be

The second conditional covers unreal or unlikely present situations: past simple in the if clause, would plus base verb in the main. The verb be takes were in formal use: If I were you, I would apologise, while spoken English allows was. Example: If I had more time, I would join the debate team, where the past tense does not refer to the past at all. Give students a one-line self-check: if you can add but I am not, it is the second conditional. Put all three conditionals side by side and change only the if clause, so the difference is visible at a glance.

Students do: write the same event three times, once in each conditional.

04 Question types and worked steps

Type	Example	Steps	Answer
Tense choice multiple choice	Pick the correct if clause tense from four options	Decide fact, prediction or hypothesis, then apply the table	The if clause never takes will
Sentence combination	Join two sentences into one conditional	Assign the content to each clause, then set the tenses	Keep the original meaning and the original time clue
Unless rewriting	Turn an unless sentence into an if sentence	Unless means if not, so flip the verb from negative to positive	Read it back and check that the negative is not doubled
Gap-fill passage	Fill five or six verbs in one paragraph	Read the whole passage for the situation, then decide each gap	One passage can mix all three conditionals, so never fill will everywhere

Sanity check (teach this): Sanity check: the whole lesson uses one table of three rows and two columns, holding the if-clause tense and the main-clause tense, and students should be able to reproduce all six cells; every example answers two questions on the spot, is it a fact and is it likely, and the tense must match the answer; rewriting tasks require the original tense to be stated before the change, so nobody changes words without changing tense; the lesson closes with the line that will never appears in the if clause, which blocks most lost marks.

05 Independent practice (3 questions)

Question	Answer	What to watch
Three-way contrast	Write the same event in each conditional	Check that the if-clause tense is paired correctly
Error hunt	Five sentences, three with will in the if clause	Check that the reason is explained, not just corrected
Unless rewriting	Two unless sentences into if not	Check that no double negative appears

06 Common mistakes and what to say

Mistake	Student writes	Say this
Using will in the if clause	Writing If it will rain, we will stay home.	Will is banned inside the if clause and lives only in the main clause, so two will verbs is automatically wrong.
Using was in the second conditional	Writing If I was you, I would go.	Hypothetical sentences take were for be, because the situation is the opposite of reality.
Mixing zero and first	Writing a general rule with will	Anything true every time takes the present simple; only a single future event takes will.
Double negative after unless	Writing unless you don’t hurry	Unless already means if not, so the verb after it must be positive.

08 Exit check (last 5 minutes)

Question	Answer	Decision
Three pairs	Present in both halves, will, would with were	A wrong pair means replay scene two
If-clause ban	No will inside the if clause	Will again means replay scene three
Unless meaning	Unless equals if not	Not knowing it means replay scene five

09 Tutor FAQ

Is the third conditional part of S3?

No. S3 covers three conditionals only, and the third, which is unreal in the past, belongs to S4 and S5, since four types in one lesson guarantees confusion.

Is the spoken If I was you acceptable?

It is common in conversation, but school tests and DSE writing expect were, so teach were to avoid disputes over marking.

Should mixed conditionals be taught?

Not yet. Fix the three types first, because mixed conditionals are an extension for students who can already separate the three.
