Lesson Plan: Exploring Tessellations in Geometry

Grade Level: 7th Grade
Subject: Geometry
Duration: 60 minutes

Lesson Objective:

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

  1. Define tessellations and distinguish between regular, semi-regular, and irregular types.
  2. Identify and correct common misconceptions about polygons and tessellations.
  3. Recognize real-world applications of tessellations in architecture and art.
  4. Create their own tessellation pattern using geometric shapes.

Materials Needed:

  • Projector and computer
  • Graph paper
  • Colored pencils
  • Rulers
  • Tablets/computers with internet access
  • Printed examples of tessellations

Lesson Structure:

1. Warm-Up (10 minutes)

  • Activity: Show images of tessellations from video games, comics, and real-world examples.
  • Discussion: Ask students to share what they observe and if they know the term for such patterns.

2. Direct Instruction (15 minutes)

  • Introduction: Define tessellations and explain the types (regular, semi-regular, irregular).
  • Clarify Misconceptions: Discuss common misunderstandings about polygons and tessellations.
  • Visual Aids: Use slides to show examples, highlighting how each type fits together without gaps.

3. Guided Practice (15 minutes)

  • Activity: Students work in pairs to identify tessellation types from printed examples.
  • Discussion: Circulate to assist and clarify any doubts.

4. Independent Practice (15 minutes)

  • Activity: Students create their own tessellation on graph paper using colored pencils and rulers.
  • Guidance: Encourage creativity and provide templates for those needing support.

5. Real-World Connections (10 minutes)

  • Presentation: Show examples of tessellations in architecture (e.g., Islamic art) and art (e.g., M.C. Escher).
  • Cultural Significance: Discuss the historical and cultural importance of these designs.

6. Assessment (5 minutes)

  • Formative: Observe student work during practice.
  • Summative: Evaluate created tessellations and understanding through a short quiz.

7. Differentiation

  • Advanced: Research and present on a specific tessellation example.
  • Support: Provide step-by-step guides for creating tessellations.

Homework/Extension:

  • Task: Create a tessellation at home and write about its real-world application.
  • Exit Ticket: Students write one thing learned and one question they have.

Reflection and Follow-Up:

  • Reflection: Note student engagement and understanding.
  • Follow-Up: Plan lessons on symmetry or advanced geometry concepts.

This lesson plan integrates geometry with art and history, ensuring an engaging and comprehensive learning experience for 7th graders.
