RI.4.8
Explain how an author uses reasons and evidence to support particular points in a text.
Objective
Students will be able to separate a point, its reasons and its evidence, and judge whether the evidence is enough.
Students are successful when they can
- Distinguishes a reason from evidence.
- Maps both to the point.
- Judges whether the support is sufficient.
What you need
- An argumentative text
- Three colours of highlighter
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — reason or evidence?
5 min- Give six statements supporting one point. Sort into reasons and evidence.
- A reason says why; evidence shows that.
Teach — three colours
13 min- Highlight the point in one colour, reasons in a second, evidence in a third.
- Do one section fully.
- Find a reason with no evidence under it and mark the gap.
- Find evidence attached to no reason and ask what it is doing there.
- Judge the section: is the support enough for the point as stated?
“A reason with no evidence is an assertion. Mark it and say so.”
Guided practice — highlight a section
12 min- Pairs highlight one section in three colours.
- They find one unsupported reason and one unattached piece of evidence.
- They write a sentence judging the support.
Independent practice
8 min- Students complete the argument page.
- The passage is on the sheet.
Close
2 min- Take one reason and its evidence, or note the gap.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Treats reasons and evidence as the same.
Why: Both come after the point and both support it.
Fix: A reason is a claim about why; evidence is a fact that shows. Different colours make it visible.
Accepts any evidence as sufficient.
Why: Evidence is present, so the point is supported.
Fix: Ask whether one example proves a general claim. Usually it does not.
Judges the point rather than the support.
Why: Agreeing or disagreeing is more natural than analysing.
Fix: Judge the support independently of whether you agree. A point you agree with can be badly argued.
If they are not there yet
- Two colours rather than three.
- One paragraph rather than a section.
If they finish early
- Find a point with strong reasons and weak evidence.
- Supply the missing evidence.
- Compare two authors' support for the same point.
Exit ticket
What point is made here? What reason and what evidence support it?
What to look for: Reason and evidence distinguished. Both named the same means the why-versus-that distinction needs another sort.

Questions about Reasons and Evidence for a Point
How long does the Reasons and Evidence for a Point 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 Reasons and Evidence for a Point teach?
CCSS.ELA-LITERACY.RI.4.8 — RI.4.8, Reading: Informational Text for Grade 4: “Explain how an author uses reasons and evidence to support particular points in a text.” In plain terms, explain which reasons and evidence hold up each of the author's points.
What do I need to teach this lesson?
An argumentative text, three colours of highlighter 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: treats reasons and evidence as the same; accepts any evidence as sufficient and judges the point rather than the support. 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: “What point is made here? What reason and what evidence support it?.” Reason and evidence distinguished. Both named the same means the why-versus-that distinction needs another sort. 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 Reasons and Evidence for a Point?
Yes — 1 printable RI.4.8 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.
