Compare and contrast the most important points and key details presented in two texts on the same topic.
Objective

Students are successful when they can
- Compares the main points.
- Compares the key details.
- Says which text is better for a stated purpose.
What you need
- Two texts on one topic with different emphases
- A two-row comparison grid: main point, key details
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — predict the difference
5 min- Read both titles and first lines. Predict how the two will differ.
- Hold the prediction to check later.
Teach — two rows, not one
13 min- Fill the main-point row for both texts.
- Fill the key-detail row for both.
- Note that texts can share a main point and differ entirely in detail, or the reverse.
- Find an example of each in the grid.
- Then answer a 'which text for this purpose' question from the grid.
“They agree about the main thing and disagree about everything under it. That happens a lot.”
Guided practice — fill the grid
12 min- Pairs complete all four cells.
- They say whether the texts are closer on points or on details.
- They answer one purpose question.
Independent practice
8 min- Students complete the comparing page.
- Both passages are on the sheet.
Close
2 min- Take one row and say how the texts compare on it.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Collapses the two rows into one comparison.
Why: Both are 'what the text says'.
Fix: Four cells, filled separately. The separation is the analysis.
Reports a difference in detail as a disagreement.
Why: Different content reads as conflict.
Fix: Ask whether either contradicts the other. Different emphases are not disagreements.
Chooses the better text by preference.
Why: One was more enjoyable.
Fix: Name the purpose first. Better is always better-for-something.
If they are not there yet
- One row rather than two.
- Give one text's cells filled.
If they finish early
- Find a genuine contradiction between the texts.
- Say which text you would trust more and why.
- Write a sentence combining both main points.
Exit ticket
Do these two texts agree on the main point? Do they use the same details?
What to look for: Two separate answers. One answer for both means the grid needs completing first.

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 Comparing Two Texts on One Subject teach?
CCSS.ELA-LITERACY.RI.3.9 — RI.3.9, Reading: Informational Text for Grade 3: “Compare and contrast the most important points and key details presented in two texts on the same topic.” In plain terms, compare the main points and details of two texts on one topic.

Two texts on one topic with different emphases, a two-row comparison grid: main point, key details 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: collapses the two rows into one comparison; reports a difference in detail as a disagreement and chooses the better text by preference. 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: “Do these two texts agree on the main point? Do they use the same details?.” Two separate answers. One answer for both means the grid needs completing first. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.

Yes — 1 printable RI.3.9 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.
