Geometric Sculpture Activity: Exploring Tessellations with Everyday Materials

Objective:
To help 4th-grade students understand tessellations by creating geometric sculptures using cardboard tubes, straws, and tape, while exploring symmetry, patterns, and spatial reasoning.

Materials Needed:

  • Cardboard tubes (from paper towel rolls)
  • Plastic straws
  • Masking tape or duct tape
  • Scissors
  • Paper and pencils for sketching
  • Rulers (optional)

Activity Outline:

  1. Introduction to Tessellations (15 minutes):

    • Show examples of tessellations (e.g., bathroom tiles, honeycombs, Islamic art).
    • Discuss key characteristics: repeating shapes, no gaps or overlaps, covers a plane.
    • Introduce symmetry and its role in tessellations.

  2. Design and Sketching (15 minutes):

    • Students brainstorm and sketch potential shapes (squares, triangles, hexagons) on paper.
    • Encourage consideration of symmetry in their designs.

  3. Building Individual Shapes (20 minutes):

    • Students construct their shapes using tubes and straws, connecting them with tape.
    • Start with simpler shapes (squares, triangles) before moving to complex ones (hexagons).

  4. Assembling the Tessellation (25 minutes):

    • Students create multiple identical shapes and assemble them into a larger tessellation.
    • Use tape to connect shapes edge-to-edge, ensuring no gaps or overlaps.
    • Discuss how symmetry aids in fitting shapes together.

  5. Reflection and Discussion (15 minutes):

    • Students reflect on challenges and solutions in small groups.
    • Class discussion on observations, problem-solving, and the role of symmetry.
    • Optional: Students present their sculptures, explaining tessellation and symmetry elements.

  6. Assessment:

    • Observe participation and engagement.
    • Evaluate sculptures for understanding of tessellation concepts.
    • Review sketches and reflections for problem-solving and understanding.

Considerations:

  • Provide examples or guides for students who struggle.
  • Ensure ample materials for each group.
  • Allocate sufficient time, possibly across two class periods with checkpoints.

Conclusion: This activity offers a hands-on approach to learning tessellations, encouraging creativity and collaboration. By designing and building their own tessellating sculptures, students gain a deeper understanding of geometric concepts while developing spatial reasoning and problem-solving skills.
