Learning Objectives ("I Can" Statements)

• I can identify the main idea of a text about turtles and their shells.
• I can find and underline important details that support the main idea.
• I can talk with a partner about the important details I found.

---

Success Criteria

• I clearly name the main idea of the story.
• I underline at least two important details in the text.
• I share my underlined details and explain why they are important with my partner.

---

Materials

• Simple nonfiction text on turtle shells (dyslexia-friendly formatting: large font, clear spacing, sans-serif font like Arial or Comic Sans, highlighted keywords)
• Colored pencils or crayons for underlining (suggested colors: blue or green for clarity)
• Chart paper with "Main Idea" and "Key Details" headings
• Partner discussion sentence stems printed on cards:
  • "The main idea is..."
  • "One important detail is..."
  • "I think this detail is important because..."

Lesson Procedure

1. Warm-up & Review (5 minutes)

• Begin with a brief recap of previous lessons using simple questions:
  "What do you remember about turtles and their shells?"
• Introduce the day’s goal: We will find the main idea and the important details that tell us how turtle shells help protect turtles.
• Write the "I Can" statements on the board and read them aloud together.

---

2. Guided Reading & Underlining (10 minutes)

• Distribute the dyslexia-friendly text about turtle shells.
• Read the text aloud once, modeling clear pronunciation and pausing to check comprehension.
• Read it a second time, this time guiding students to underline key details that support the main idea using colored pencils.
• Model one example on the chart paper: underline a sentence, then say aloud why it is important.

---

3. Partner Talk (8 minutes)

• Pair students (consider pairing higher readers with readers who need extra support).
• Give each pair the sentence stem cards.
• Instruct pairs to take turns sharing which details they underlined and why those details are important.
• Circulate to listen, prompt, and scaffold discussion where needed.
• Use open questions to deepen thinking:
  "How does this detail help us understand how the turtle’s shell protects it?"

---

4. Whole Group Wrap-up (5 minutes)

• Ask volunteers to share one main idea and one key detail they underlined.
• Write their responses on chart paper to reinforce concepts visually.
• Revisit the "I Can" statements. Ask students to give a thumbs-up if they feel confident or a thumbs-sideways if they want more practice.

Differentiation Strategies

Learner Type	Strategy
Struggling readers	Use dyslexia-friendly text version; provide verbal prompts for underlining; allow drawing key details.
English learners	Pair with strong English speakers; use picture clues in the text; label main idea/key details visually.
Advanced learners	Challenge to write their own key detail sentence; add an extension activity (see below).
Students with attention needs	Use fidget tools during reading; keep underlining activity brief and focused; use partner talk for engagement.

---

Extension Activity for Advanced Learners

• Have students write or dictate a short sentence explaining why the turtle’s shell is important, using one or two key details as evidence in their explanation.
• Encourage them to illustrate their sentence with a drawing of a turtle showing its shell in action.

---

Assessment

• Informal observation during partner talks to check understanding.
• Review underlined details on students’ texts.
• Listen for accurate main idea identification and relevant key details shared in whole group discussion.

---

Notes for Teacher

• Encourage use of positive language and praise during partner discussions to build confidence.
• Utilize clear and explicit language during instruction to support all learners.
• Use multi-sensory approaches: seeing text, underlining, speaking, and discussing.
