Mastering Fractions & Decimals

---

Overview

Grade: 4th
Duration: 45 minutes
Class Size: 5 students
Unit: Decoding Decimals and Fractions (Lesson 4 of 4)
Standards Alignment:

• CCSS.MATH.CONTENT.4.NF.C.6 — Understand decimal notation for fractions, and compare decimal fractions.
• CCSS.MATH.CONTENT.4.NF.C.7 — Compare two decimals to hundredths by reasoning about their size.

---

Learning Objectives

By the end of this lesson, students will be able to:

• I can convert fractions to decimals accurately.
• I can compare decimals and fractions and explain which is greater or smaller.
• I can collaborate with peers to teach and explain fraction and decimal concepts.
• I can create an anchor chart summarizing all key fraction and decimal concepts we learned this week.

---

Success Criteria

Students will demonstrate mastery by:

• Correctly converting at least 4 fractions to decimals in the mastery check with 80% accuracy or above.
• Accurately comparing two given decimals or fractions and explaining their reasoning.
• Effectively participating in peer teaching by clearly communicating concepts to classmates.
• Contributing to the creation of a comprehensive and easy-to-understand class anchor chart.

Materials Needed

• Whiteboard & markers
• Fraction and decimal anchor chart materials (poster paper, colored markers)
• Tablets or computer for video viewing
• Printed mastery check worksheets (dyslexia-friendly font and layout)
• Fraction and decimal flashcards
• Timer
• Dyslexia-friendly fonts printed handouts with summary key points

Lesson Breakdown

1. Warm-Up & Review (10 minutes)

• Activity: Quick whole-class oral recap of key concepts from previous lessons. Use flashcards with fraction and decimal pairs. Ask students to explain each pair’s relationship aloud.
• Differentiation: For students with reading challenges, provide visual fraction/decimal models and simplified verbal prompts.
• Teacher Notes: Use encouraging language and scaffolding questions, e.g., "What does this fraction mean?" "How can we write it as a decimal?"

2. Video Summary (5 minutes)

• Show a concise, engaging video (~3-5 mins) that covers:
  • How to convert fractions to decimals.
  • Comparing decimals and fractions visually and numerically.
• Dyslexia-Friendly Option: Provide a printed transcript of the video using a dyslexia-friendly font to follow along.

3. Anchor Chart Creation (10 minutes)

• Group Activity:
  • Collaborate with students to build a final “Mastering Fractions and Decimals” anchor chart summarizing the unit’s key concepts:
    • Fraction to decimal conversions.
    • Decimal comparison strategies.
    • Visual models (number line, place value blocks).
  • Assign each student a section to draw or write (using colored markers).
• Differentiation: Allow students to express understanding through writing, drawing, or oral explanation depending on comfort level.

4. Peer Teaching Mini-Lesson (10 minutes)

• Activity:
  • Students pair up or sit in a circle, take turns teaching each other one concept they feel confident about (e.g., "I will teach you how to convert 1/4 to 0.25").
  • Encourage use of models, the anchor chart, or flashcards during teaching.
• Extension: Advanced learners prepare an additional explanation or tip to share.
• Teacher Role: Circulate to prompt deeper questioning and provide one-on-one support as needed.

5. Mastery Check (7 minutes)

• Assessment: Provide a short worksheet with 5 questions:
  • Convert fractions to decimals (e.g., 3/10, 7/100).
  • Compare decimal pairs and write which is greater (e.g., 0.4 vs. 0.39).
  • Explain answers briefly in simple sentences (or drawings for alternative expression).
• Dyslexia-friendly answer sheets with ample spacing and clear font.
• Immediate feedback and support for students who struggle.

6. Wrap-Up & Reflection (3 minutes)

• Quick round of “I can” statements: each student shares one thing they learned or feel proud of.
• Remind students about the success criteria and next steps if any need additional practice or want to work on extension projects.

Differentiation Strategies

• Provide visual aids and manipulatives for conceptual understanding.
• Use dyslexia-friendly fonts and layouts in printed materials.
• Offer verbal explanations and encouragement for students with language processing challenges.
• One-on-one mini-sessions during peer teaching or mastery check for students needing extra support.

---

Extension Activities

• Invite advanced learners to create a short presentation or digital slide show explaining a challenging concept in fractions and decimals.
• Encourage illustration of real-life examples where fractions and decimals are used (recipes, money, measurements).
• Optional math journal entry: write and illustrate their favorite fraction-decimal conversion tip.

---

Reflection Notes for Teacher

• Observe peer teaching effectiveness and student confidence during the mini-lesson.
• Use mastery check results to identify concepts needing reteach or enrichment.
• Encourage self-assessment with “I can” statements and promote growth mindset.
