Building Strong Paragraphs

Overview

Students will learn a reusable paragraph structure—hook or opening, background or context, thesis or focus statement, supporting details, and conclusion. They will compare how this structure changes across informative, narrative, opinion, and explanatory writing, then plan one paragraph and complete a short homework task in each mode.

Learning intentions

Students will be able to:

• Identify the purpose and structure of informative, narrative, opinion, and explanatory paragraphs.
• Write an engaging opening, relevant background, and clear thesis or focus statement.
• Group ideas logically for a specific task, purpose, and audience.
• Explain how paragraph parts work together to develop the whole text.

Success criteria

• I can name the purpose of each writing type.
• I can write a hook or opening, background information, and a clear thesis or focus statement.
• I can organize related ideas in a logical order.
• I can write a conclusion that connects to the paragraph’s main idea.

Curriculum links

• Introduce a topic or text, state an opinion when appropriate, and organize ideas logically to support the purpose.
• Analyze how sentences and paragraphs relate to one another and to the whole text.
• Introduce a topic clearly, group related information logically, and use headings or illustrations when useful.
• Provide a concluding statement related to the information or explanation presented.
• Produce clear, coherent writing appropriate to task, purpose, and audience.

Lesson structure (60 minutes)

1. 0–7 min · Hook and retrieval. Display a picture of a crowded school garden using the opening image slide and ask, “How could four writers use this same picture?” Students silently write one possible opening, then share with a partner. Invite four examples and label them informative, narrative, opinion, or explanatory.

2. 7–17 min · Teach the paragraph frame. Use the paragraph structure slides to model the common frame: opening or hook, background/context, thesis or focus statement, supporting details, and conclusion. Explain that a thesis states the writer’s main claim or focus; a narrative may use a situation and purpose rather than a formal thesis. Students annotate the frame on the four writing types practice worksheet.

3. 17–29 min · Compare four examples. Read the four short model paragraphs on the model paragraph slides. Use the same topic, “Should our school add a garden?” to show the differences:

• Informative: “School gardens are outdoor spaces where students grow plants and study nature.” The thesis focuses on what the garden provides.
• Narrative: “The seed packet slipped from my hand just as the bell rang.” The opening creates a moment; the focus is the narrator’s experience.
• Opinion: “Our school should add a garden because it would give students hands-on science practice.” The thesis states a position and reasons.
• Explanatory: “A garden helps plants grow through a sequence of connected steps.” The focus previews a process or cause-and-effect explanation.

Students identify the opening, background, thesis or focus, and conclusion in each example. Check answers through whole-class discussion.

4. 29–41 min · Guided classwork: sort and plan. In pairs, students complete the first section of the four writing types practice worksheet. They match each prompt to a writing type and plan the beginning of one paragraph for each:

• Informative: Explain three benefits of school gardens.
• Narrative: Tell about the day a class planted its first seed.
• Opinion: Argue whether every school should have a garden.
• Explanatory: Explain how a seed becomes a plant.

Partners use the sentence stems on the planning and discussion slides and check that each plan includes an appropriate opening, background, and thesis or focus statement. Circulate and conference with students.

5. 41–52 min · Independent writing. Students choose one prompt and write a complete paragraph of 6–8 sentences on the four writing types practice worksheet. Require a clear opening, background or context, thesis or focus statement, at least two logically grouped details, and a related conclusion. Students underline the opening, circle the thesis or focus, and box the conclusion.

6. 52–60 min · Share, assess, and assign homework. Invite two or three students to read different writing types. Use the review and exit prompt slides to review: “How does the writer’s purpose change the paragraph structure?” Students complete the exit ticket: name the writing type they used, identify their thesis or focus statement, and explain one revision they would make. Assign the homework choices below.

Resources

• the paragraph structure and model writing deck
• the four writing types practice worksheet
• Projector or interactive display
• Pencils and colored pencils
• Student notebooks
• Timer
• Exit-ticket slips or notebook paper

Assessment

• During modeling and pair work, listen for students correctly identifying purpose, opening, background, thesis or focus, details, and conclusion.
• Review the independent paragraph for logical organization, a clear thesis or focus statement, and a related conclusion.
• Use the exit ticket to identify students who confuse informative and explanatory writing or who need support writing a thesis.

Differentiation

• Support students with a color-coded paragraph frame, word banks, sentence starters, and orally rehearsed ideas before writing. Provide reduced choices or allow dictation/speech-to-text for students with writing or fine-motor needs.
• For EAL students, preview words such as purpose, explain, evidence, opinion, process, and conclusion with simple definitions and visuals. Pair students strategically and model complete sentences.
• For students needing additional support, provide partially completed examples and conference first with the opening and thesis/focus before asking for the full paragraph.
• Advanced learners should write a second paragraph in a different mode about the same topic, then explain how the purpose changed the hook, thesis or focus, evidence, and conclusion.

Homework

Students complete one short example for each writing type in their notebook:

• Informative: Write a paragraph explaining three benefits of school gardens. Include a topic introduction, background information, grouped facts, and a conclusion.
• Narrative: Write a paragraph about planting a first seed. Include a setting, characters, a clear event, sensory details, and an ending.
• Opinion: Write a paragraph arguing whether the school should add a garden. State a position, give two reasons, and conclude by restating the opinion.
• Explanatory: Write a paragraph explaining how a seed becomes a plant. Use sequence words such as first, next, then, and finally, and end with a concluding statement.
