Ratios and Proportions Review

Overview

This 60-minute lesson is designed to help 7th-grade students consolidate their understanding of ratios and proportions before their final unit assessment. Through engaging review activities and a formative assessment, students will demonstrate mastery as outlined in the Common Core State Standards (CCSS). The lesson incorporates multisensory and dyslexia-friendly instructional strategies to support all learners.

Standards Alignments

• CCSS.MATH.CONTENT.7.RP.A.1: Compute unit rates associated with ratios of fractions, including ratios of lengths, areas, and other quantities measured in like or different units.
• CCSS.MATH.CONTENT.7.RP.A.2: Recognize and represent proportional relationships between quantities.
• CCSS.MATH.CONTENT.7.RP.A.3: Use proportional relationships to solve multistep ratio and percent problems.

---

Learning Objectives

• I can review and summarize my understanding of ratios and proportions.
• I can solve problems involving unit rates, ratios, and proportional reasoning confidently.

---

Success Criteria

Students will:

• Complete a comprehensive review quiz with 85% accuracy or higher.
• Explain ratio and proportion concepts clearly during peer discussions.
• Use visual representations such as tape diagrams or double number lines to solve problems.

---

Materials

• Whiteboard and markers
• Printed review worksheets with dyslexia-friendly font (e.g. OpenDyslexic) and high-contrast color scheme
• Index cards with ratio and proportion problems
• Chart paper or interactive digital whiteboard
• Timer

Lesson Timeline

1. Warm-up (10 minutes)

Activity: Quick Ratio Flash**

• Distribute index cards with simple ratio problems (e.g., 3:4, unit rates like 45 miles in 3 hours) to students randomly.
• Students pair up and quiz each other solving the problems aloud.
• Teacher circulates, providing immediate feedback and scaffolding where needed.

Dyslexia-Friendly Tip: Cards use large font, clear spacing, and avoid decorative fonts. Students encouraged to underline key numbers.

2. Interactive Whole-Class Review (15 minutes)

Activity: Concept Sort and Discussion

• Teacher prepares 12 cards with terms, examples, and non-examples: ratios, unit rates, equivalent ratios, proportions, tape diagrams, double number lines.
• Students come up in small groups to place them under four headers on the board: Ratios, Unit Rates, Proportions, Visual Models.
• Discuss reasoning as a class; teacher models how to justify classification and correct misunderstandings.

Note: Encourage students with dyslexia to verbalize their thoughts. Use color-coded cards and borders for categories to visually support organization.

3. Guided Practice (20 minutes)

Activity: Collaborative Problem Stations

• Set up four stations around the room, each with 3 problems focused on these key skills:

  • Station 1: Finding unit rates with fractions and whole numbers
  • Station 2: Identifying and creating equivalent ratios
  • Station 3: Solving proportions using cross-multiplication
  • Station 4: Applying visual models to real-world ratio problems

• Students work in groups of 4-5 and rotate every 5 minutes. Each station includes scaffolded hints for students who need extra support.

• Teacher and aides facilitate, ensuring all students engage and understand.

---

4. Independent Review Assessment (10 minutes)

Activity: Quiz

• Students complete a short, dyslexia-friendly paper quiz covering the concepts reviewed.
• Includes multiple-choice, short answer, and one visual representation question (e.g., label a tape diagram).

---

5. Closing and Reflection (5 minutes)

• Students self-assess using the "I can" statement on a tracker sheet:
  • Check "Yes," "Almost," or "Not yet" for their confidence in reviewing ratios and proportions.
• Invite 2-3 students to share out strategies or insights they found helpful.
• Teacher previews next lesson: real-life applications of ratios and proportions.

---

Differentiation and Accessibility

• Provide copies of all text in dyslexia-friendly font and clear layout.
• Use multisensory activities (talking, writing, moving to stations).
• Visual aids and color coding to support organization and memory.
• Allow extra time for quiz if needed.

---

Reflection for Teacher

• Note which concepts required more reteaching during discussions and stations.
• Review quiz results to identify individual or class weaknesses for intervention before the unit test.
• Collect feedback on activity engagement and clarity for ongoing improvement.
