Grades 2-3 Informational Writing Lesson

Lesson Summary

The lesson models how students can turn a brainstorm into an organized informational paragraph. The class writes about what plants need to live, including sunlight, water, and soil, and practices keeping details connected to one main idea.

Main Ideas and Writing Process

1. Review what you know

   • Students silently think about what they know about the topic in an “I review.”
   • They then share ideas with classmates in a “table review.”
   • The teacher presents these activities as ways to prepare for writing.

2. Brainstorm and sort ideas

   • Students share facts about ecosystems, including sunlight, plants, water, soil, and different kinds of animals.
   • The class groups related ideas and considers where each one belongs.
   • They identify the central subject of the brainstorm: plants and what they need.
   • The teacher guides students to state the big idea: plants need many things in order to live or grow.

3. Understand the parts of an informational paragraph

   • Topic sentence: States the big idea and what the paragraph is about.
   • Details: Explain or support the topic sentence.
   • Conclusion: Restates the main idea in different words.

4. Use an organizer to plan the topic sentence

   • Students use a “secret formula”:
     • Setting: Tells when and where. The class considers phrases such as “every day,” “all year long,” and “on planet Earth.”
     • Subject: Identifies who or what the information is about—in this case, plants.
     • Big idea: Says what the paragraph will explain: plants need many things to live.
   • Students sketch quick symbols or notes, then reread them to check whether the opening makes sense.

5. Plan details and develop them into sentences

   • Students use the question, “What is one thing a plant needs in order to live?” to select details from the brainstorm.
   • The class develops details about:
     • Sunlight: Plants use sunlight to make food.
     • Water: Plants take up water through their roots, and it moves through the plant.
     • Soil: Soil provides nutrients that plants use.
   • Students turn notes and sketches into complete sentences, adding information when needed to clarify a detail.
   • They practice varying their references to plants—for example, using “these living things”—to avoid repeating the same word.

6. Write the conclusion

   • Students return to the topic sentence and restate its central idea in different words.
   • The conclusion should reinforce the paragraph’s message rather than introduce an unrelated idea.

7. Reread, punctuate, and draft

   • Students reread the organizer and say their sentences aloud before writing.
   • They check for capital letters, commas where appropriate, and periods at the ends of sentences.
   • They indent the paragraph and use a “talking write” process: say a sentence while writing it, then compare the draft with the organizer.
   • The teacher emphasizes rereading to catch mismatches between the plan and the written text.

The lesson also uses frequent student responses, partner and table discussions, gestures, and checks for understanding to help students remember the paragraph structure and writing steps.
