The lesson
Warm-up — follow this
5 min- Explain how a letter reaches a house, missing the sorting.
- Wait for somebody to notice.
Teach — two halves, and be exact
13 min- Model 'I followed it to the postbox. After that I am not sure.'
- Say why exactness helps: the explainer knows where to restart.
- Add the Grade 1 step: name what you think is missing, not just that something is.
- Answer the question and have the child say it back.
- Do a second with a different gap.
“Where exactly did it stop making sense? Not 'somewhere'.”
Guided practice — plant and find
12 min- Pairs give explanations with a deliberate gap.
- The listener names the gap precisely and asks about it.
- They swap.
Independent practice
8 min- Students complete the finding-the-gap page.
- Read each explanation aloud.
Close
2 min- Give a gappy explanation. Take the best question.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Says 'I do not get it'.
Why: It is all they can locate.
Fix: Ask for the last part they did follow.
Guesses the missing step instead of asking.
Why: Guessing feels more capable.
Fix: A guessed step is often wrong and now nobody knows.
Pretends to follow.
Why: Not understanding feels like failing.
Fix: Build the gap in deliberately so asking is the correct response.
If they are not there yet
- Give the question frame.
- Three-stage explanations.
If they finish early
- Find a gap nobody else noticed.
- Supply the missing step yourself and check.
- Ask about a gap in a written explanation.
Exit ticket
Where did this explanation stop making sense? Write a question about that part.
What to look for: A precise location and a question. 'I do not get it' means the two-halves shape needs practising.

Questions about Finding the Gap
How long does the Finding the Gap lesson take?
40 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, guided practice 12 min, independent practice 8 min, close 2 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 Finding the Gap teach?
D4.5.K-2 — D4.5.K-2, Communicating Conclusions and Taking Informed Action for Kindergarten to Grade 2: “Ask and answer questions about explanations.” In plain terms, ask and answer questions about an explanation.
What do I need to teach this lesson?
Explanations of local processes with a gap 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: says 'I do not get it'; guesses the missing step instead of asking and pretends to follow. 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: “Where did this explanation stop making sense? Write a question about that part.” A precise location and a question. 'I do not get it' means the two-halves shape needs practising. 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 Finding the Gap?
Yes — 1 printable D4.5.K-2 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 Finding the Gap 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.
