Standards Alignment

Common Core State Standards - Mathematics:
CCSS.MATH.CONTENT.6.RP.A.3 - Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
CCSS.MATH.PRACTICE.MP2 - Reason abstractly and quantitatively.
CCSS.MATH.PRACTICE.MP4 - Model with mathematics.

Learning Objectives

By the end of this lesson, students will:

• I can create a real-world scenario that involves ratios and proportions.
• I can demonstrate an understanding of how ratios and proportions apply to everyday life.
• I can explain the relationships in my project using mathematical reasoning.

---

Success Criteria

• Students develop a clear and creative real-world project that shows the use of ratios and proportions.
• Students use correct mathematical vocabulary and reasoning when presenting their projects.
• Students are able to answer questions or justify their ratio choices confidently.

---

Materials Needed

• Project guideline handout (dyslexia-friendly font: OpenDyslexic or Arial, font size 14, with plenty of spacing)
• Graph paper / drawing paper
• Colored pencils or markers
• Calculators (optional)
• Large poster boards or digital presentation tools (Google Slides or PowerPoint)
• Student notebooks
• Timer

Lesson Breakdown

1. Introduction (10 minutes)

• Activate prior knowledge: Brief review of ratios and proportions — use visuals like double number lines or tape diagrams on the board.
• Explain the project: Each student will create a project showing a real-world problem that uses ratios and proportions. Possible examples include recipes, map scaling, or mixing paint colors.
• Use an “I can...” statement:
  • "I can create a project that applies ratios and proportions."
• Distribute the project guideline handout with instructions and suggested scenarios. Read the handout aloud with the class, pausing to check understanding.

2. Planning Phase (10 minutes)

• Students brainstorm ideas individually or with a partner.
• Encourage students to pick something meaningful or interesting to them.
• Support students to outline:
  • What is their ratio or proportion problem?
  • How will they show their problem mathematically?
• Teacher circulates, checking ideas, asking guiding questions.
• Dyslexia-friendly tip: Provide graphic organizer sheets with simple boxes for students to jot down their problem description, ratio expressions, and visuals they plan to include.

3. Project Creation (25 minutes)

• Students work independently or in pairs to create their project on poster board or digitally.
• They should:
  • Clearly state their real-world scenario.
  • Define the ratio or proportion used.
  • Show calculations or diagrams demonstrating the proportional relationship.
  • Use visuals (drawings, charts, color coding) to clarify ideas.
• Teacher supports students needing extra help, especially those with reading challenges, by offering reading aloud or breaking tasks into smaller steps.

4. Presentation and Peer Review (10 minutes)

• Select 5 students (or groups) to present their projects briefly (2 minutes each).
• After each presentation, a couple of peers ask one question or make one comment focusing on understanding the ratio/proportion.
• Reinforce respectful listening and constructive feedback.
• Use sentence starters for peer questions, e.g., “Can you explain how you found this ratio?” or “I like how you showed…”

5. Wrap-Up and Reflection (5 minutes)

• Group discussion: What did we learn about ratios and proportions today?
• Teacher re-emphasizes the I can... statement and success criteria.
• Students write a quick exit ticket answering:
  • What is one new thing I learned about ratios and proportions?
  • What part of my project was the easiest? The hardest?
• Collect exit tickets for teacher review.

Differentiation / Accessibility

• Dyslexia-Friendly Reading: Use handouts with OpenDyslexic font or Arial, size 14+, and high-contrast colors (black text on pale yellow background).
• Provide audio versions of written materials or use text-to-speech tools if available.
• Allow use of calculators and visual aids for struggling students.
• Pair students strategically for peer support.
• Break project tasks into small steps with clear checklists to reduce overwhelm.

---

Assessment

• Formative: Observation during brainstorming, project work, and presentations.
• Summative: Evaluate final projects using a rubric measuring:
  • Creativity and clarity of real-world scenario (30%)
  • Correct use and explanation of ratios and proportions (40%)
  • Presentation skills and ability to answer questions (20%)
  • Visual aids and organization (10%)

---

Teacher Reflection Prompts

• Did students engage more deeply when creating their own projects?
• Did the dyslexia-friendly materials support all learners effectively?
• Which student questions revealed deeper understanding or misconceptions?
• How could this project be adapted for virtual or hybrid learning environments?

This lesson allows students to take ownership of their learning by connecting ratios and proportions to meaningful real-life problems while supporting diverse learners through clear scaffolds and accessibility considerations.
