Supporting Details | Small Group
In this 20-minute small-group reading lesson, students learn how supporting details strengthen a main idea, improve comprehension, and help readers explain text evidence clearly. Students will practice finding details in a short passage and connecting them to the main idea.
| Term | Definition |
|---|---|
| Main idea | The most important point the author wants the reader to understand. |
| Supporting detail | A fact, example, reason, or description that explains or proves the main idea. |
| Evidence | Information from the text that supports a claim or idea. |
| Text structure | The way an author organizes information in a text. |
Ask students: 'What makes an explanation convincing?' Briefly guide them to examples and facts. Introduce the idea that details help prove a main point.
Respond orally and give quick examples of facts, examples, or reasons they notice in everyday explanations.
Display a short passage. Read one paragraph aloud and think aloud to identify the main idea. Highlight one sentence that states the main point and two details that support it. Explain how each detail connects back to the main idea.
Follow along, listen, and mark the same main idea and details on their copy.
Give students a second short paragraph or the next section of the text. Prompt them to work in pairs or as a group to find the main idea and at least three supporting details. Ask guiding questions such as: 'Which sentence gives an example?' and 'Which detail helps explain the main point?'
Underline or highlight the main idea and supporting details, then share reasoning with the group using text evidence.
Ask each student to complete the graphic organizer by writing one main idea and two supporting details from the text. Circulate and give quick feedback.
Independently record their answers and explain in writing how one detail supports the main idea.
Review: 'A strong main idea is supported by details that explain, prove, or expand it.' Ask one student to share a detail and tell how it supports the main idea.
State one supporting detail and explain its connection to the main idea in a sentence.
Supporting details make a text clearer and more convincing by explaining or proving the main idea.
Formative assessment will come from teacher observation, student responses, and the completed graphic organizer showing an accurate main idea and at least two relevant supporting details with an explanation of how one detail supports the main idea.
Students will read a short article or textbook section at home and write the main idea plus three supporting details. Then they will explain in 2-3 sentences how one detail supports the main idea.
