Produce complete sentences when appropriate to task and situation in order to provide requested detail or clarification.
Objective
Students will be able to expand a short answer into a complete sentence that supplies the missing detail.
Students are successful when they can
- Turns a short answer into a full sentence.
- Adds the detail the listener needed.
- Judges when a short answer is enough.
What you need
- A set of question-and-short-answer pairs
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — did that answer it?
5 min- Give four question-and-short-answer pairs. For each, ask whether the answer was enough.
- Two will be, two will not.
Teach — the sentence carries the detail
13 min- Take a short answer that was not enough. Ask what the listener still does not know.
- Expand it into a sentence that supplies exactly that.
- Show a full sentence that is long but still leaves the detail out. Length is not the point.
- Take a case where a short answer was fine and say why expanding would be odd.
- Name the skill: adding what is missing, not adding words.
“A longer answer is not automatically a better one. What did they still need to know?”
Guided practice — expand four
12 min- Pairs take four exchanges and decide which need expanding.
- They expand the two that do.
- They say what detail each expansion supplied.
Independent practice
8 min- Students complete the complete-sentences page.
- It gives short answers to judge and expand.
Close
2 min- Give a short answer. Take the expansion and the detail it added.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Expands every answer whether or not it needs it.
Why: The rule was heard as 'always use full sentences'.
Fix: Include cases where short is right. Judgement is the standard, not compliance.
Adds words without adding information.
Why: Longer feels like more effort and more effort feels like better.
Fix: Ask what the listener now knows that they did not. If nothing, the words were padding.
Produces a fragment and calls it a sentence.
Why: It is long and it answers the question.
Fix: Check for the subject and the verb. Both, every time.
If they are not there yet
- Two exchanges rather than four.
- Give the missing detail to include.
If they finish early
- Expand an answer in two ways for two different listeners.
- Say what a short answer would imply that a full one does not.
- Write a question a short answer cannot answer.
Exit ticket
'Where did you go?' 'Park.' Expand that answer so it supplies the detail.
What to look for: A full sentence carrying new information. More words with the same content means the what-do-they-now-know test needs another run.
