Exploring Geometry through Origami

Title: Exploring Geometry through Origami

Compliance: Common Core State Standards for Mathematics

Subject: Mathematics

Summary: Engage eighth-grade students in a hands-on project that combines the art of origami with the principles of geometry.

Topic: Geometry and Origami

Learning Outcomes:

• Know the basic principles of geometry, including angles, lines, and shapes.
• Understand how to apply geometric concepts to real-world situations.
• Create and manipulate origami shapes to explore geometric properties.
• Apply problem-solving skills to analyze and solve geometric puzzles.

Methodology:

This lesson will be conducted over several class periods and will involve a combination of teacher-led instruction, hands-on activities, and group work. The students will be introduced to the basic principles of geometry and then apply their knowledge to create origami shapes that demonstrate these concepts.

Resources/Materials:

• Origami paper (square sheets)
• Rulers
• Pencils
• Scissors
• Protractors
• Geometric shapes (optional)

Instructions:

Day 1:

1. Introduce the concept of geometry and its relevance in everyday life.
2. Discuss the basic principles of geometry, including angles, lines, and shapes.
3. Show examples of origami shapes that can be created using geometric principles.
4. Provide each student with a square sheet of origami paper.
5. Guide the students in creating a simple origami shape, such as a square or triangle.

Day 2:

1. Review the concepts of angles and lines.
2. Introduce the concept of symmetry and its importance in geometry.
3. Guide the students in creating origami shapes that demonstrate symmetry, such as a butterfly or a snowflake.
4. Encourage the students to explore different folding techniques to create symmetrical shapes.

Day 3:

1. Review the concepts of angles, lines, and symmetry.
2. Introduce the concept of polygons and their properties.
3. Guide the students in creating origami shapes that represent different polygons, such as a pentagon or a hexagon.
4. Encourage the students to experiment with different folding techniques to create polygons with varying numbers of sides.

Day 4:

1. Review the concepts of angles, lines, symmetry, and polygons.
2. Introduce the concept of three-dimensional shapes and their properties.
3. Guide the students in creating origami shapes that represent three-dimensional objects, such as a cube or a pyramid.
4. Encourage the students to explore different folding techniques to create three-dimensional shapes.

Activities:

Throughout the lesson, the students will engage in the following activities:

• Creating origami shapes that demonstrate geometric concepts
• Exploring different folding techniques to manipulate origami shapes
• Collaborating with peers to solve geometric puzzles using origami
• Presenting their origami creations and explaining the geometric principles behind them

Assessment:

The students will be assessed based on their participation in class activities, their ability to create origami shapes that demonstrate geometric concepts, and their understanding of the geometric principles discussed throughout the lesson. Additionally, the students will be given a problem-solving task where they will need to apply their knowledge of geometry and origami to solve a given puzzle.
