Explain how supporting questions help answer compelling questions in an inquiry.
Objective
Students will be able to match a supporting question to the compelling question it serves and say how it helps.
Students are successful when they can
- Matches a supporting question to its compelling question.
- Says what part of the big answer the small one supplies.
- Spots a supporting question that serves nothing.
What you need
- One compelling question written large
- Eight supporting question cards, two of them useless
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — too big to answer
5 min- Post 'was the railway worth its cost to the valley?' and ask for an answer in one go.
- Let the attempt fail. Name why: too much at once.
Teach — breaking it into parts
15 min- Ask what you would need to know first. Take 'how many wharf families lost work?'
- Write it under the big question and say what part it supplies: the cost side.
- Add 'what did a third class fare cost?' and say what it supplies: who could use it.
- Add a card that serves nothing: 'what colour was the engine?' Ask which part it supplies.
- Name the test: a supporting question earns its place by supplying a named part of the answer.
- Show that the same small question can serve two different big ones, and that is fine.
“Which part of the big answer does this one give us?”
Guided practice — build the ladder
13 min- Groups take one compelling question and four supporting cards.
- They place each card and write the part it supplies, discarding any that supply nothing.
- Groups present one ladder and defend a discard.
Independent practice
9 min- Students complete the 'How Small Questions Serve Big Ones' page.
- Check matches for a reason, not just a line.
Close
3 min- Keep the class's best ladder on the wall for the rest of the enquiry.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Matches by shared vocabulary.
Why: Both questions say 'railway', so they must go together.
Fix: Ask which part of the big answer it supplies. Shared words are not shared work.
Thinks a supporting question must be easy.
Why: Small sounds like simple.
Fix: 'How many families lost work?' is small in scope and hard to answer. Scope, not difficulty.
Keeps every card because each is about the topic.
Why: Discarding feels like being wrong.
Fix: Discarding is the skill. Say what part it supplies; if there is none, it goes.
If they are not there yet
- Two supporting cards and one compelling question.
- Give the part supplied and ask which card matches.
If they finish early
- Write a third supporting question the ladder is missing.
- Take one supporting question and find a second big question it also serves.
- Say which supporting question the sources cannot answer at all.
Exit ticket
Write one supporting question for 'who did the railway serve?' and say what part of the answer it supplies.
What to look for: A narrower question plus the part it supplies. A question with no part named means the ladder idea has not landed.

Questions about Small Questions Serving a Big One
How long does the Small Questions Serving a Big One lesson take?
45 minutes, split across 5 timed sections: warm-up 5 min, teach 15 min, guided practice 13 min, independent practice 9 min, close 3 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does Small Questions Serving a Big One teach?
D1.4.3-5 — D1.4.3-5, Developing Questions and Planning Inquiries for Grade 3 to Grade 5: “Explain how supporting questions help answer compelling questions in an inquiry.” In plain terms, explain how the smaller questions add up to an answer to the big one.
What do I need to teach this lesson?
One compelling question written large, eight supporting question cards, two of them useless and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: matches by shared vocabulary; thinks a supporting question must be easy and keeps every card because each is about the topic. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “Write one supporting question for 'who did the railway serve?' and say what part of the answer it supplies.” A narrower question plus the part it supplies. A question with no part named means the ladder idea has not landed. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with Small Questions Serving a Big One?
Yes — 1 printable D1.4.3-5 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.
Is Small Questions Serving a Big One free to use?
Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on 7 September 2026. Please do not resell it or republish it as your own.
