geometrical shapes working model – maths project – maths tlm – diy for exhibition

Creating a geometrical shapes working model using cardboard and colored paper is a fantastic way to showcase various shapes for a math project or exhibition.

Here’s a simple and engaging DIY project:

Materials Needed:

  1. Cardboard
  2. Colored paper
  3. Ruler
  4. Pencil
  5. Scissors
  6. Glue or tape
  7. Markers
  8. Wooden dowels or straws
  9. Small weights (e.g., beads, paper clips)

Shapes to Include:

  1. Square
  2. Rectangle
  3. Circle
  4. Triangle (equilateral, isosceles, scalene)
  5. Pentagon
  6. Hexagon
  7. Octagon

Steps to Create the Geometrical Shapes Working Model:

Step 1: Prepare the Base:

  • Cut a large piece of cardboard to serve as the base for your working model.

Step 2: Draw and Cut Out Shapes:

  • Draw and cut out templates for each shape from colored paper. Use different colors for visual appeal.
  • Label each template with the name of the shape.

Step 3: Attach Shapes to Dowels:

  • Glue or tape each shape template onto wooden dowels or straws.
  • For stability, attach small weights (e.g., beads or paper clips) to the bottom of each shape.

Step 4: Attach Dowels to the Base:

  • Attach the dowels or straws with the shape templates to the cardboard base. Place them in a way that allows for easy rotation.

Step 5: Optional – Label the Shapes:

  • Create labels or index cards with information about each shape, including the number of sides, angles, and any interesting facts.

Step 6: Display and Explain:

  • Set up your working model at the exhibition table.
  • Demonstrate each shape by rotating the corresponding dowel or straw.

Step 7: Optional – 3D Shapes:

  • To expand the project, create 3D shapes (cube, pyramid, cylinder, etc.) using additional templates and dowels.


  • During the exhibition, explain the characteristics of each shape.
  • Encourage visitors to interact with the model, rotating the shapes and observing their properties.

This working model provides a hands-on and visual representation of various geometrical shapes, making it an interactive and educational display for a math project or exhibition. It allows students and visitors to physically engage with the model, enhancing their understanding of geometry concepts.
