how to make fraction working model using cardboard

Creating a fraction working model using cardboard and two holes can be a simple yet effective way to illustrate the concept of fractions.

Here’s a DIY project for a basic fraction model:

Materials Needed:

  1. Cardboard
  2. Ruler
  3. Pencil
  4. Craft knife or scissors
  5. Colored paper or markers
  6. String or yarn
  7. Two brads or paper fasteners
  8. Hole puncher
  9. Glue or tape

Steps to Create the Fraction Working Model:

Step 1: Prepare the Base:

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

Step 2: Draw and Cut Two Rectangles:

  • Draw two rectangles on colored paper or cardboard. These rectangles will represent different parts of a whole.
  • Cut out the rectangles carefully.

Step 3: Label the Rectangles:

  • Label each rectangle with a fraction. For example, you can label one as “1/3” and the other as “2/3.”

Step 4: Attach the Rectangles:

  • Attach each rectangle to the cardboard base using glue or tape. Position them side by side, leaving space between them.

Step 5: Create Holes:

  • Use a hole puncher to create a hole near the top of each rectangle.

Step 6: Attach String:

  • Cut two pieces of string or yarn. Thread each piece through the holes in the rectangles and tie knots at the back to secure them.

Step 7: Connect with Brads:

  • Use brads or paper fasteners to connect the other ends of the strings to the cardboard base. This allows the rectangles to rotate.

Step 8: Display and Demonstrate:

  • Set up your fraction working model at the exhibition table.
  • Rotate the rectangles using the strings to demonstrate how changing the position of each part affects the fraction.

This simple fraction working model provides a hands-on and interactive representation of basic fraction concepts using cardboard and two holes.

It’s a great way to engage viewers and help them understand how fractions represent parts of a whole.
