Wh- questions ask for specific information — not just yes or no, but who, what, where, when, why, and how. They are built on the same inversion structure as yes/no questions, with a question word added at the front. Understanding how to form them — and how to choose the right question word — is essential for everyday communication.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
Read these pairs. The first is a yes/no question. The second is a wh- question. What has changed?
A wh- question = question word + the rest of the yes/no question. The inversion is still there — the auxiliary still moves before the subject (or in the case of be, be still moves to the front). The question word simply appears at the very beginning. 'Does he live?' becomes 'Where does he live?' — 'where' added at the front, everything else stays the same. This is the key insight: wh- questions are just yes/no questions with a question word at the front. Students who already know yes/no question formation only need to add the question word at the beginning. The inversion rule does not change.
Now look at these wh- questions. Notice that 'how' combines with other words to create different questions. What does each combination ask about?
How much = asks about quantity of uncountable things (things you cannot count individually: water, money, time, rice, information). How many = asks about quantity of countable things (things you can count: students, books, days, children, lessons). How long = asks about duration (time). How often = asks about frequency (how many times). How far = asks about distance. How old = asks about age. The 'how + adjective/adverb' pattern is extremely productive in English — you can combine 'how' with almost any adjective or adverb to ask a specific quantity or degree question. Teaching this as a pattern (not a list to memorise) is more useful.'
Now look at these questions. Something is wrong with the word order in each one. Can you find the error and correct it?
Sentences 1–4: the inversion is missing. 'Where she is going?' — 'she is' is statement word order. The question needs inversion: 'Where is she going?' The question word does NOT change the inversion rule. Students often learn the question word but forget to invert — especially in longer, more complex questions. Sentence 5: 'how much students' is wrong because 'students' is countable. Use 'how many students'. A simple test: can you count it individually? (one student, two students, three students) → how many. Can you not count it individually? (water, money) → how much.'
THE MOST COMMON WH- QUESTION ERROR — forgetting to invert:
Students often place the question word correctly but then revert to statement word order:
A USEFUL CLASSROOM RULE:
After every question word, the AUXILIARY comes next — before the subject.
What DOES she want?
Where IS he going?
When DID they arrive?
Why DIDN'T they come?
If students can say the yes/no question first, then add the question word at the front, they almost never make this error:
Step 1: Does she live here? Step 2: Where + does she live? = Where does she live?
This two-step approach is one of the most effective teaching tools for wh- questions.
Is the main verb 'be'? → question word + be + subject. Is it a non-be verb, present? → question word + do/does + subject + base verb. Is it past? → question word + did + subject + base verb. Is the question about quantity of something countable? → how many. Uncountable? → how much. Is there a question word but no auxiliary before the subject? → always wrong — add the auxiliary.
Choose the correct question word or form to complete each wh- question.
Each question contains an error. Write the correct version and explain why — then reveal the answer.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — BUILD FROM YES/NO (5 minutes): Write five yes/no questions on the board. Ask students to turn them into wh- questions by adding a question word at the front.
STEP 2 — QUESTION WORD MEANINGS (5 minutes): Write the six question words on the board. Give a statement and ask which question word would produce that answer.
STEP 3 — HOW PHRASES (8 minutes): Write the how phrases on the board: how much / how many / how long / how often / how far / how old. Give students a topic (their school) and ask them to produce one how question for each phrase.
STEP 4 — THE INVERSION MISTAKE HUNT (5 minutes): Write five wh- questions with the inversion missing. Students correct them in pairs.
STEP 5 — QUESTION INTERVIEW (5 minutes): Students prepare five wh- questions to interview a classmate about their life and teaching experience. They conduct the interview and report back one interesting fact they learned. This produces authentic, motivated wh- question use.
Use directly in class — copy, adapt, or read aloud. No printing needed.
For each strategy, choose the option that best describes where you are now.
