Student Actions

Listen, review the vocabulary, and ask any clarifying questions before starting.

Independent Reading10 minutes

Teacher Actions

Distribute the passage and organizer. Remind students to read the text once for understanding and a second time to look for repeated ideas and important details.

Student Actions

Read the passage quietly and mark important words or phrases.

Main Idea Identification10 minutes

Teacher Actions

Instruct students to write the topic and then state the main idea in a complete sentence. Encourage them to use text evidence instead of guessing.

Student Actions

Identify the topic and write a main idea sentence on the organizer.

Supporting Details10 minutes

Teacher Actions

Prompt students to choose three details from the passage that support the main idea. Circulate briefly to check for understanding and redirect as needed.

Student Actions

Highlight or list three supporting details and explain how each one connects to the main idea.

Independent Response7 minutes

Teacher Actions

Ask students to complete a short written response: ‘What is the main idea, and which details support it?’

Student Actions

Write a concise response using evidence from the text.

Wrap-Up3 minutes

Teacher Actions

Invite students to compare their answers with a partner for one minute or share one strong example aloud if time allows.

Student Actions

Share or self-check their responses and prepare to submit work.

Support

Provide a shorter passage with more obvious repeated ideas.
Offer a main idea sentence frame: 'The main idea is ___. The author shows this by ___.'.
Pre-highlight one or two key details for students who need extra support.
Allow oral responses before writing for students who benefit from verbal processing.

Challenge

Ask students to explain why one detail is more important than another.
Have students write a second possible main idea and defend why it is less accurate.
Invite students to create their own supporting detail question for a partner.
Require students to cite the exact words or phrases that helped them decide the main idea.

Checks for Understanding

Observe whether students can separate topic from main idea.
Review organizers for a complete main idea sentence and accurate details.
Listen for evidence-based explanations during independent work check-ins.
Quickly scan written responses for alignment between the main idea and supporting details.

Closure

Students state or write one sentence naming the main idea and one detail that supports it. Reinforce that strong readers use details to prove what a text is mostly about.

Homework

Read a short passage at home or reread today’s passage. Write the main idea in one sentence and list two supporting details from the text.
