RI.1.2

Identify the main topic and retell key details of a text.

Objective

Students will be able to name the main topic of an information text and give three key details from it.

Students are successful when they can

  • Names the topic of the "Bees" text as "bees and how they live," not "honey" or "flowers."
  • Gives three details that are about the topic: bees make honey, live in a hive, help flowers grow.
  • Leaves out a sentence that does not belong when one is added.

What you need

  • The "Bees" text (in the Teach section) on chart paper
  • A table organizer: topic on the tabletop, three details on the legs
  • The printable practice sheet linked at the end of this plan

The lesson

Warm-up — the odd one out

5 min
  1. Read four sentences: "Dogs have four legs. Dogs can bark. Dogs like to run. The sky is blue."
  2. Ask: "Which one does not belong?" "The sky is blue." Ask why. Fish for "It is not about dogs."
  3. Say: "The other three all tell us about one thing — dogs. That one thing is the main topic."

Teach — topic on top, details underneath

13 min
  1. Read: "Bees are busy insects. They fly from flower to flower to collect nectar. They use the nectar to make honey. Bees live together in a hive. Each bee has a job, like cleaning or guarding the door. Bees also help flowers grow by carrying pollen."
  2. Ask: "What is this text mostly about?" Take answers. Someone may say "honey." Ask: "Is the hive about honey? Are the jobs about honey?" No. "What is every sentence about?" Bees.
  3. Draw a table: write "Bees and how they live" on the tabletop.
  4. Ask for details that hold the table up. Write one on each leg: "make honey from nectar," "live together in a hive," "help flowers grow."
  5. Test it: "If a leg were about cats, would the table stand?" No — every leg has to hold up the same top.
  6. Read the topic and the three details back as a retell: "This text is about bees. Bees make honey. They live in a hive. They help flowers grow."
“The main topic is the one thing every sentence is about. The key details are the facts that hold it up.”

Guided practice — build the organizer

12 min
  1. Give pairs a new text: "Frogs start life as tiny eggs in a pond. The eggs hatch into tadpoles. Tadpoles have tails and live in water. Slowly they grow legs. Their tails get shorter. Then they hop out of the pond as frogs."
  2. Pairs draw a table and write the topic on top (how a frog grows) and three details on the legs.
  3. Then they retell the text to each other using only the table: topic first, then the legs.
  4. Circulate and check the topic. If a pair writes "tadpoles," ask: "Is the last sentence about tadpoles?" Help them find a bigger topic.
  5. Share one table and check all three legs hold up the top.
“Read your topic, then read each leg. Does every leg belong under that top?”

Independent practice

8 min
  1. Students complete the main-topic page: reading the text and answering the topic and detail questions.
  2. Remind them to read the whole text before choosing the topic.
  3. Ask finishers to write one sentence that would not belong in the text and explain why.

Close

2 min
  1. Read: "Bees live in a hive. Bees make honey. My cat is gray." Ask which detail does not belong.
  2. Fish for "My cat is gray — it is not about bees."

What goes wrong, and why

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

Names one detail as the topic: "It is about honey."

Why: One detail is the most interesting or the one they remember, so it feels like what the whole text is about.

Fix: Test the topic against each sentence: "Is this sentence about honey?" When most are not, ask what every sentence has in common.

Gives a topic that is too big: "It is about animals."

Why: They have the right family of idea but have not narrowed it to what this text is about.

Fix: Ask "Which animal? What about it?" A topic should say what this text tells you, not every text like it. "Bees and how they live" is about this text.

Gives three details that are not from the text: "Bees sting. Bees are yellow."

Why: They know true facts about bees and offer those, because they are about the topic.

Fix: Ask "Where does the text say that?" Point back to the chart. Details for this text have to come from this text.

If they are not there yet

  • Give three possible topics and ask which one every sentence fits: honey, bees, flowers.
  • Number the sentences and let the child choose three numbers for the legs.
  • Use a shorter text of four sentences, all clearly about one thing.

If they finish early

  • Write a one-sentence retell that includes the topic and two details joined by "and."
  • Add a fourth leg from another book about bees and explain where it came from.
  • Write a short text of four sentences on a topic of your own with one hidden odd-one-out, for a partner to find.

Exit ticket

What is the "Bees" text mainly about? Give three details that support it.

What to look for: "Bees and how they live" with three details from the text, such as honey, hive, pollen. "Honey" as the topic means they need to test the topic against each sentence. Details not in the text mean they are using what they already knew.

Questions about Main Topic and Key Details

How long does the Main Topic and Key Details 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 Main Topic and Key Details teach?

CCSS.ELA-LITERACY.RI.1.2 — RI.1.2, Reading: Informational Text for Grade 1: “Identify the main topic and retell key details of a text.” In plain terms, say what the text is mostly about and give the key facts.

What do I need to teach this lesson?

The "Bees" text (in the Teach section) on chart paper, a table organizer: topic on the tabletop, three details on the legs 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: names one detail as the topic: "It is about honey."; gives a topic that is too big: "It is about animals." and gives three details that are not from the text: "Bees sting. Bees are yellow.". 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 is the "Bees" text mainly about? Give three details that support it.” "Bees and how they live" with three details from the text, such as honey, hive, pollen. "Honey" as the topic means they need to test the topic against each sentence. Details not in the text mean they are using what they already knew. 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 Main Topic and Key Details?

Yes — 1 printable RI.1.2 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 Main Topic and Key Details 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.
