Lesson Breakdown

Time	Activity	Description	Purpose
0-5 min	Engage & Activate Prior Knowledge	Begin with a quick warm-up question: “What is a fraction? Can you show me 3/4 using your fingers or drawing?” Prompt a few students to share responses. Use fraction tiles to visually demonstrate their answers.	Activate prior knowledge and build interest.
5-15 min	Visual Representation Exploration	Distribute fraction tiles to each student. Have them model fractions like 1/2, 2/3, 3/4, 5/6. Next, introduce the number line strips. Students place these fractions on number lines individually and then discuss where each fraction lies in relation to each other. Display a large poster number line for group discussion.	Build conceptual understanding using concrete models and number lines (MP4).
15-25 min	Comparing Fractions in Pairs	In pairs, students receive two fraction cards (e.g., 3/8 and 5/12). Using fraction tiles and number lines, they determine which is greater and explain their reasoning. Circulate and ask probing questions to foster deep understanding (MP1, MP7).	Develop comparison skills using visual tools and peer collaboration.
25-40 min	Adding and Subtracting Fractions Mini-lesson	Demonstrate on the board adding 2/3 + 1/4 using fraction tiles and equivalent fractions to find a common denominator. Emphasize the reasoning process step-by-step: find common denominator → convert fractions → add numerators → simplify if needed. Students then try two problems independently on their dry erase boards (e.g., 3/5 + 2/7 and 7/8 - 3/6).	Improve procedural fluency through guided practice and visual models.
40-50 min	Real-World Application Challenge	Present 3 real-life scenarios involving fractions (recipe adjustments, sharing items, or measuring lengths). In groups of 3-4, students solve these problems and create a short explanation or visual model to demonstrate the solution. Encourage creativity such as drawing, using number lines, or fraction tiles.	Engage problem-solving skills and model real-world applications of fractions (MP1, MP4).
50-58 min	Formative Assessment & Reflection	Each student writes on a sticky note one fraction they found easy to compare or add, and one question or confusion they still have. Collect and quickly review to adjust next lesson. Ask a few students to share their “aha moments.”	Check understanding and promote metacognition.
58-60 min	Closure and Preview	Summarize key points on the board. Preview the next lesson: multiplying and dividing fractions. Encourage students to think of where fractions appear in everyday life outside class.	Reinforce learning and build curiosity.

Differentiation Strategies

• For advanced learners: Challenge with adding mixed numbers or converting improper fractions during the independent practice.
• For struggling learners: Provide additional fraction tile practice and 1:1 support during partner activities. Use simplified fractions for practice.
• Visual learners: Use color-coded fraction tiles and number lines to highlight equivalencies.
• Kinesthetic learners: Encourage physical manipulation of fraction pieces and number line walking activity outside class if possible.

---

Assessment Ideas

• Formative: Observation of student reasoning during partner work, responses on dry erase boards, and sticky note reflections.
• Exit Ticket: On a small card, ask students to compare two fractions and explain which is greater using a visual model or number line.
• Homework Suggestion: Create a fraction story problem from their daily life and solve it using fraction addition or subtraction.

Teacher Tips to 'Wow'

• Use storytelling to frame the real-world problems (e.g., "You’re a chef trying to double the recipe") — contextualizing fractions hooks interest and deepens understanding.
• Incorporate movement by having volunteer students physically place fraction cards on a large number line taped on the floor, turning math into a dynamic experience.
• Use student-created fraction models or drawings as wall displays to build classroom community and showcase different strategies.
• Continually press students to explain why fractions compare or operate the way they do — deep reasoning supports long-term retention.
