RI.2.9

Compare and contrast the most important points presented by two texts on the same topic.

Objective

Students will be able to name the most important points in two texts on the same topic, say which points both share and which only one gives.

Students are successful when they can

  • Lists the two or three most important points in each text.
  • Says one point both texts make: "Both say earthquakes happen when plates move."
  • Says one point only one text makes: "Only Text B says how to stay safe."
  • Uses "both," "only" and "but" when comparing.

What you need

  • Text A and Text B on earthquakes (in the Teach section), one copy per pair
  • A Venn diagram on the board with circles "Text A," "Text B" and "Both"
  • Two highlighter colors
  • The printable practice sheet linked at the end of this plan

The lesson

Warm-up — same and different

5 min
  1. Ask two children to tell the class what they had for breakfast. Ask: "What did both have? What did only one have?"
  2. Draw a quick Venn diagram of the answers.
  3. Say that today we do the same with two texts about one topic.

Teach — both and only

13 min
  1. Read Text A: "Earthquakes. The ground is made of huge pieces of rock called plates. The plates move very slowly. Sometimes they get stuck. Pressure builds up until they slip, and the ground shakes."
  2. Read Text B: "Staying Safe in an Earthquake. An earthquake happens when plates under the ground slip. The ground can shake for a few seconds. If you are indoors, get under a strong table. Hold on until the shaking stops."
  3. Ask: "What are the most important points in Text A?" Highlight: plates move, they get stuck, pressure builds, they slip and the ground shakes.
  4. Ask the same for Text B: plates slip, the ground shakes, get under a table, hold on.
  5. Fill the Venn: Both — earthquakes happen when plates slip and the ground shakes. Only A — how pressure builds up. Only B — how to stay safe.
  6. Model the sentences: "Both texts say the ground shakes when plates slip. But only Text B tells us what to do in an earthquake."
“Find what both texts say. Then find what only one says. Use "both," "only" and "but."”

Guided practice — fill the Venn

12 min
  1. Give pairs two short texts on camels. Text A: "Camels live in deserts. They store fat in their humps. They can go days without water." Text B: "Camels live in deserts. They have long eyelashes to keep out sand. People ride camels to cross the desert."
  2. Pairs highlight the important points in two colors and fill their own Venn diagram.
  3. Each pair writes one "Both" sentence and one "Only" sentence.
  4. Share answers and check: "Both say camels live in deserts." "Only Text A talks about water." "Only Text B talks about people riding them."
“Read both before you decide. A point is only "both" if you can find it in each text.”

Independent practice

8 min
  1. Students complete the printable. One sheet gives two texts on one topic with a question under each and a question comparing them; the other asks which text says more about a point.
  2. Remind them to find the point in each text before writing "both."

Close

2 min
  1. Ask: "If you wanted to know how to stay safe, which earthquake text would you read? Why?"

What goes wrong, and why

Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.

Writes "Both texts are about camels" as the only comparison.

Why: The shared topic is the most obvious sameness, and it feels like the answer to "how are they alike?"

Fix: Say that the topic is the starting line, not the answer. Ask: "What do both texts tell us about camels?"

Puts a point in "Both" that is only in one text: "Both say camels have long eyelashes."

Why: Once they have read both texts the facts merge in memory, and they cannot recall which said what.

Fix: Use two highlighter colors and only put a point in "Both" when both colors are on it.

Compares small details instead of the most important points: "Text A has three sentences and Text B has four."

Why: Surface differences are easy to see and count; important points need judgment.

Fix: First list each text's two biggest points, then compare only those. Ask: "Which point would a reader most need?"

If they are not there yet

  • Pre-highlight the important points so the child only sorts them into the Venn.
  • Use two texts of two sentences each.
  • Give sentence frames: "Both texts say ___. Only Text A says ___."

If they finish early

  • Explain which of the two earthquake texts would be more useful for a visitor to a place with earthquakes, and why.
  • Write a third short text that adds a point neither text made.
  • Find a point where the two texts would disagree if they said more, and explain.

Exit ticket

Text A: "Bees make honey. Bees live in hives." Text B: "Bees make honey. Bees help flowers grow." Write one "both" and one "only" sentence.

What to look for: "Both say bees make honey." "Only Text A says bees live in hives" (or only B, flowers). "Both are about bees": the topic, not a point. A wrong "only": they lost track of which text said what — use two colors.

Questions about Comparing Two Texts on a Topic

How long does the Comparing Two Texts on a Topic 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 Comparing Two Texts on a Topic teach?

CCSS.ELA-LITERACY.RI.2.9 — RI.2.9, Reading: Informational Text for Grade 2: “Compare and contrast the most important points presented by two texts on the same topic.” In plain terms, compare the main points two texts make about the same topic.

What do I need to teach this lesson?

Text A and Text B on earthquakes (in the Teach section), one copy per pair, a Venn diagram on the board with circles "Text A," "Text B" and "Both", two highlighter colors 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: writes "Both texts are about camels" as the only comparison; puts a point in "Both" that is only in one text: "Both say camels have long eyelashes." and compares small details instead of the most important points: "Text A has three sentences and Text B has four.". 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: “Text A: "Bees make honey. Bees live in hives." Text B: "Bees make honey. Bees help flowers grow." Write one "both" and one "only" sentence.” "Both say bees make honey." "Only Text A says bees live in hives" (or only B, flowers). "Both are about bees": the topic, not a point. A wrong "only": they lost track of which text said what — use two colors. 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 Comparing Two Texts on a Topic?

Yes — 1 printable RI.2.9 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.

Is Comparing Two Texts on a Topic 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 October 8, 2026. Please do not resell it or republish it as your own.
