Creating a working model to demonstrate the four types of triangles using a square box design that opens and hides information is a fantastic way to make learning interactive and engaging.

Here’s a step-by-step guide to making this model using cardboard, color paper, and chopsticks.

Materials Needed:

  • Cardboard (for the base, square boxes, and center label)
  • Color paper (for covering and labeling)
  • Scissors or craft knife
  • Glue or hot glue gun
  • Markers or pens
  • Ruler
  • Chopsticks (for the opening mechanism)
  • Brass fasteners or paper fasteners (for attaching the rotating disks)

1. Prepare the Base and Square Boxes

  1. Base Preparation:
    • Cut a large square piece of cardboard for the base. Cover it with color paper for a neat finish.
  2. Square Boxes:
    • Cut four smaller square pieces of cardboard. These will be the individual boxes representing each type of triangle.
    • Cover these square pieces with color paper.
  3. Center Label:
    • Cut a smaller square piece of cardboard for the center label. Cover it with color paper and write “Types of Triangles” on it.

2. Label and Attach Boxes

  1. Label Boxes:
    • Label each box with one type of triangle. The four types of triangles are:
      • Equilateral Triangle
      • Isosceles Triangle
      • Scalene Triangle
      • Right Triangle
  2. Attach Boxes to the Base:
    • Arrange the four labeled boxes around the center label on the base.
    • Attach them to the base with glue, ensuring there is enough space for the opening and closing mechanism.

3. Create Definitions and Examples

  1. Definitions and Examples:
    • On each box, write the definition of the triangle type and draw an example showing the angles and sides.
    • Use color paper to make the examples visually appealing and easy to understand.

4. Create the Opening Mechanism

  1. Chopsticks Mechanism:
    • Attach a chopstick to each box with brass fasteners or glue. This will act as a lever to open and close the information flap.
  2. Information Flaps:
    • Cut small pieces of cardboard to create flaps that can hide and reveal the information on each box.
    • Cover the flaps with color paper and label them with “Open” on one side and “Close” on the other.

5. Assemble the Model

  1. Attach Information Flaps:
    • Use brass fasteners to attach the flaps to the boxes. Ensure they can be easily lifted and lowered using the chopstick mechanism.
  2. Position the Flaps:
    • Ensure the flaps are evenly spaced and can open and close without obstruction.

6. Final Touches

  1. Ensure Functionality:
    • Check that all flaps can easily open and close to reveal and hide the information on each box.
  2. Add Visual Aids:
    • Use different colors for different triangle types to make them stand out.
    • Add small arrows or lines to clearly illustrate the sides and angles of each triangle.

Example Layout:

  • Top Left Box: Equilateral Triangle with definition and example (all sides equal, all angles 60°).
  • Top Right Box: Isosceles Triangle with definition and example (two sides equal, two angles equal).
  • Bottom Left Box: Scalene Triangle with definition and example (no sides equal, no angles equal).
  • Bottom Right Box: Right Triangle with definition and example (one angle 90°).

Steps to Make the Model:

  1. Base Setup:
    • Cut a large square piece of cardboard for the base and cover it with color paper.
    • Attach the center label to the middle of the base.
  2. Square Boxes:
    • Cut four smaller squares for the triangle types and cover them with color paper.
    • Label each box with the type of triangle and attach it around the center label.
  3. Definitions and Examples:
    • Write definitions and draw examples on each box.
    • Attach flaps to each box using brass fasteners.
    • Attach chopsticks to the flaps to act as levers.
  4. Final Touches:
    • Ensure all flaps open and close smoothly.
    • Add visual aids and color coding for clarity.

By following these steps, you can create an interactive and educational model that demonstrates the four types of triangles effectively.
