Present Simple: Facts, Habits, and Routines

What this session covers

The present simple is one of the first tenses learners encounter, but it is not as simple as it first appears. It is used for facts that are always true, for habits and routines that happen regularly, and for general truths about the world. Forming it correctly — especially the third-person singular — causes persistent errors in learner writing and speech. As a teacher, understanding both the form and the meaning of the present simple will help you explain it clearly and respond to learner errors with confidence.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
Think about how you currently introduce the present simple to your learners — do you focus on form first, or meaning first? What works well and what is difficult?
Q2
Which of these have you seen your learners do: forget the -s in the third person (e.g. 'she walk'), use present continuous for habits (e.g. 'I am going to school every day'), or add -s in questions and negatives (e.g. 'Does she teaches')?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
The sun rises in the east.
Water boils at 100 degrees.
Teachers in this school start work at 7 a.m.

Look at the verbs. Are these things happening right now, or are they always true? What does this tell you about when we use this tense?

None of these actions are happening at this exact moment — but all of them are true all the time, or true as a regular pattern. The present simple does not mean 'happening now'. It means 'this is a fact, a habit, or a regular truth'. This is one of the most important things for learners to understand: the present simple is not really about the present moment — it is about things that are generally or repeatedly true. Confusing it with present continuous (which IS about right now) is one of the most common errors at this level.

2
I teach English. / You teach English. / We teach English. / They teach English.
She teaches English. / He teaches English. / The teacher teaches English.

What is different about the third group? When exactly does the verb change its form?

The third-person singular (he, she, it — and any singular noun like 'the teacher') adds -s or -es to the verb. This is the only subject that changes the verb form in the present simple. All other subjects (I, you, we, they) use the base form. The -es ending is used after verbs ending in -ch, -sh, -ss, -x, or -o: teach → teaches, wash → washes, go → goes, do → does. Verbs ending in consonant + y change to -ies: study → studies, carry → carries. These spelling rules are small but important.

3
She teaches science. (positive)
She does not teach science. (negative)
Does she teach science? (question)

Look at the negative and question forms. What has happened to the verb 'teach'? What is 'does' doing?

In the negative and question, 'does' appears and carries the third-person -s. Because 'does' already shows third person, the main verb goes back to its base form: 'teach', not 'teaches'. This is the source of the very common error 'Does she teaches?' The -s can only be on one word: either the main verb in a positive sentence, or the auxiliary 'does' in a question or negative. Never both. The same logic applies to 'do' for I/you/we/they: 'Do they teach?' not 'Do they teaches?'

The Pattern — What You Just Discovered

The present simple is formed with the base form of the verb for most subjects, and with -s or -es for third-person singular (he, she, it). It is used for facts, habits, routines, and general truths. In negatives and questions, do or does acts as the auxiliary and the main verb returns to its base form.

Special Rule / Notes

FREQUENCY ADVERBS AND PRESENT SIMPLE
Frequency adverbs — always, usually, often, sometimes, rarely, never — are strong signals for the present simple. They tell us how often a habit or routine happens. These adverbs go before the main verb but after the verb 'be': 'She always arrives early.' / 'He is never late.' Teaching learners to recognise these words as signals for the present simple helps them make better tense choices.

PRESENT SIMPLE FOR TIMETABLES
In English, the present simple is used for fixed schedules and timetables even when talking about the future: 'The exam starts at 9 a.m. tomorrow.' 'The term ends on Friday.' This can be surprising for learners who expect a future form here.

THIRD-PERSON -S IS UNIQUE TO PRESENT SIMPLE
The third-person -s rule only applies to the present simple. It does not apply to any other tense. This is a feature unique to this tense, which is why it receives so much attention in the classroom.

🎥

HOW TO CHECK PRESENT SIMPLE - Is this a fact, habit, routine, or general truth? → Present simple. - Is the subject he, she, it, or a singular noun? → Add -s or -es to the verb. - Is it a negative? → Use don't or doesn't + base form. Never add -s to the main verb. - Is it a question? → Use do/does + subject + base form. Never add -s to the main verb. - Do you see always, usually, often, sometimes, rarely, never? → Present simple is almost certainly needed.

Common Student Errors

She walk to school every day.
She walks to school every day.
WhyThird-person singular (she) needs -s on the verb in the present simple.
He don't understand the question.
He doesn't understand the question.
WhyThird-person singular negative uses 'doesn't', not 'don't'.
Does she teaches English?
Does she teach English?
WhyWhen 'does' is the auxiliary, the main verb must be in its base form. The -s is already on 'does'.
I am going to school every day.
I go to school every day.
WhyFor habits and routines, use present simple — not present continuous.
She studys hard every night.
She studies hard every night.
WhyVerbs ending in consonant + y change to -ies in the third person: study → studies.

Check Your Understanding — Part 1

Choose the correct form of the verb to complete each sentence.

The head teacher ______ (arrive) at school before 7 a.m. every day.___________
______ the students ______ (understand) the instructions?___________
She ______ (not / teach) mathematics — she teaches English.___________
Water ______ (freeze) at zero degrees.___________
The teacher always ______ (write) the date on the board first.___________

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence contains one error. Write the correct sentence and explain the mistake.

The school close at 5 p.m. every day.
Write the correct sentence:
Explain why it is wrong:
The school closes at 5 p.m. every day.
'The school' is third-person singular. In the present simple, we add -s to the verb: 'closes'.
Do the head teacher visit every class?
Write the correct sentence:
Explain why it is wrong:
Does the head teacher visit every class?
'The head teacher' is singular, so the auxiliary must be 'does', not 'do'.
She doesn't comes to the staffroom at lunchtime.
Write the correct sentence:
Explain why it is wrong:
She doesn't come to the staffroom at lunchtime.
After 'doesn't', the main verb must be in its base form. 'Comes' should be 'come'.
He teachs three different classes every week.
Write the correct sentence:
Explain why it is wrong:
He teaches three different classes every week.
'Teach' ends in -ch, so it takes -es in the third person: 'teaches', not 'teachs'.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — WHAT IS ALWAYS TRUE? (5 minutes): Ask learners to call out three things that are always true about their school — facts that are the same every day. Write their sentences on the board. Underline the verbs. Ask: 'Are these things happening right now? Or are they always true?' Establish that these are facts and routines — not actions happening at this exact moment.

2

STEP 2 — SPOT THE PATTERN (5 minutes): Point to the sentences on the board. Ask: 'Look at the verbs. Do any of them end in -s or -es? Which ones? Why?' Guide learners to notice the third-person -s. Write a simple table: I/you/we/they + base form / he/she/it + -s or -es. Ask for two or three more examples.

3

STEP 3 — NEGATIVES AND QUESTIONS (8 minutes): Take one positive sentence from the board. Ask learners to make it negative, then a question. Guide them to see that 'does' takes the -s and the main verb returns to its base form. Repeat with two or three more sentences. Focus on third-person singular — this is where most errors occur.

4

STEP 4 — MY DAILY ROUTINE (7 minutes): Ask learners to think about their morning routine before school. In pairs, they take turns telling each other five things they do every morning. Their partner asks one question using 'Do you...?' or 'Does your...?' Listen and note any patterns of error to address at the end.

5

STEP 5 — ERROR ROUND (5 minutes): Read five sentences aloud — some correct, some with one error. After each one, ask: 'Correct or not correct?' If not correct, ask a learner to fix it and say why. Address the most common errors you heard during the routine activity.

Ready-to-Use Classroom Materials

Use directly in class — copy, adapt, or read aloud. No printing needed.

1 True About Our School
Ask learners to produce five true sentences about their school using the present simple. At least two must use a third-person singular subject (e.g. 'The head teacher...', 'Our school...'). Learners share with a partner, who checks the verb forms.
Example sentences
The school has four classrooms.
The head teacher arrives before 7 a.m.
Teachers mark books every evening.
Students do not bring phones to class.
The school closes at 4 p.m.
2 He/She/It — Third Person Drill
Say a sentence in first person (I...). Ask learners to change it to third person (She...). Go quickly around the class. The focus is on adding -s or -es correctly, including spelling changes.
Example sentences
Teacher: 'I teach English.' → Learner: 'She teaches English.'
Teacher: 'I go home at 5 p.m.' → Learner: 'He goes home at 5 p.m.'
Teacher: 'I study in the evenings.' → Learner: 'She studies in the evenings.'
3 Find the Error on the Board
Write five sentences on the board — some correct, some with one error each. Ask learners to work in pairs to find and correct the errors. Discuss as a class.
Example sentences
1. She walk to school every morning. (✗ → walks)
2. Do the teacher explain clearly? (✗ → Does)
3. He doesn't comes on Fridays. (✗ → come)
4. They always arrive on time. (✓)
5. The student studys very hard. (✗ → studies)

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Focus on the third-person -s as a priority — this is the single most common present simple error and appears in almost every piece of learner writing.
Teach the spelling rules for -es and -ies explicitly: verbs ending in -ch, -sh, -ss, -x, -o take -es; verbs ending in consonant + y take -ies.
Use frequency adverbs (always, usually, often, sometimes, never) as classroom prompts — they naturally invite present simple sentences.
Remind learners that do/does returns the main verb to its base form — this one rule prevents many of the most common errors in questions and negatives.
When learners write about their routines or general facts, read specifically for present simple errors — these are easy to miss when reading for meaning.

Key Takeaways

1 The present simple is used for facts, habits, routines, and general truths — not for actions happening at this exact moment.
2 Third-person singular (he, she, it) adds -s or -es to the verb — this is the only subject that changes the verb form.
3 In negatives and questions, do or does acts as the auxiliary and the main verb returns to its base form — the -s is never on both words.
4 Spelling rules matter: teach → teaches, go → goes, study → studies — learners need to know these patterns explicitly.
5 Frequency adverbs (always, usually, often, sometimes, never) are reliable signals that the present simple is needed.
