D1.4.3-5
Explain how supporting questions help answer compelling questions in an inquiry.
Objective
Students will be able to build a set of supporting questions and say what part of the answer each supplies.
Students are successful when they can
- Matches supporting questions to a compelling one.
- Names the part of the answer each supplies.
- Spots a gap the set does not cover.
What you need
- One compelling question on the board
- Ten supporting question cards, two of them useless
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — answer it in one go
5 min- Post 'what made the region grow?' and ask for an answer immediately.
- Let the attempt collapse and name why.
Teach — parts of an answer
17 min- Take 'which district gained most people?' and say what part it supplies: where growth happened.
- Take 'how many were born outside the region?' Part: whether growth came from migration.
- Take 'what did the harbour land?' Part: what the growth was built on.
- Add a useless card: 'what were the vessels called?' Ask which part it supplies.
- Name the test: a supporting question earns its place by supplying a named part.
- Then the harder move: look at the parts you now have and name the gap.
- The gap here is why people came, which no card yet covers.
“Which part of the big answer does this one give us, and what is still missing?”
Guided practice — build and audit
15 min- Groups build a set of four supporting questions under one compelling question.
- They label the part each supplies and discard anything that supplies none.
- They then name one gap their set does not cover and write a question for it.
Independent practice
10 min- Students complete the 'Feeding the Big Question' page.
- Check each match carries a reason, not just a line.
Close
3 min- Adopt the strongest set as the unit's supporting questions.
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 mention the region.
Fix: Ask which part of the answer it supplies. Shared words are not shared work.
Thinks a full set means a complete answer.
Why: Four cards look thorough.
Fix: Audit the parts. A set of four can miss the part that matters most.
Keeps a card because it is interesting.
Why: Discarding feels wasteful.
Fix: Interesting and useful are different. Say the part or drop the card.
If they are not there yet
- Three cards and one compelling question.
- Give the part supplied and ask which card matches.
If they finish early
- Find one supporting question that serves two compelling questions.
- Name a gap that no surviving source could fill.
- Order the set so each question sets up the next.
Exit ticket
Write a supporting question for 'who bore the cost of the region's growth?' 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 audit idea has not landed.

Questions about Feeding the Big Question
How long does the Feeding the Big Question lesson take?
50 minutes, split across 5 timed sections: warm-up 5 min, teach 17 min, guided practice 15 min, independent practice 10 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 Feeding the Big Question 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 on the board, ten 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 full set means a complete answer and keeps a card because it is interesting. 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 a supporting question for 'who bore the cost of the region's growth?' 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 audit 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 Feeding the Big Question?
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 Feeding the Big Question 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.
