how to make types of angles working model – maths project

by

Here’s a creative and interactive types of angles working model design for your math project using the mentioned materials. This model will help demonstrate different angles (acute, obtuse, right, etc.) and engage students effectively.

Design Idea: Rotating Angle Viewer

Materials Required:

  1. Cardboard: For the base and frame.
  2. Color Paper: For decoration and labeling.
  3. Push Pin: To create a rotating joint.
  4. Protractor Template: To measure and show angles.
  5. Chopstick: As a rotating arm.
  6. Marker or Pen: For writing labels.
  7. Glue or Tape: To fix materials in place.

Step-by-Step Instructions:

1. Prepare the Base:

  • Cut a rectangular piece of cardboard (approx. 12 x 8 inches).
  • Cover it with colored paper for a neat look.

2. Attach the Protractor Template:

  • Paste the printed protractor template at the center of the cardboard.
  • Ensure it is securely fixed and aligned with the base.

3. Create the Rotating Arms:

  • Cut two chopsticks or cardboard strips (approx. 6 inches each).
  • Attach one end of each stick to the center of the protractor using a push pin. This will allow the sticks to rotate freely around the protractor.

4. Mark Angle Types:

  • Use the protractor to mark specific angles:
    • 0°–90°: Acute Angles (highlight in one color, e.g., green).
    • 90°: Right Angle (highlight in another color, e.g., blue).
    • 90°–180°: Obtuse Angles (highlight in a different color, e.g., yellow).
    • 180°: Straight Angle (highlight in red).
  • Label each section with its type.

5. Add Labels and Decorations:

  • Cut small paper triangles or rectangles for labels and write the angle names (e.g., Acute, Right, Obtuse).
  • Attach these labels to the corresponding sections of the protractor.

6. Test the Rotation:

  • Rotate the sticks to form different angles. Use one stick as a fixed arm and the other as the movable arm.
  • Demonstrate how the angle changes and point to the labels for the type of angle.

7. Add an Interactive Element:

  • Add a small arrow on the movable arm pointing toward the angle on the protractor for better clarity.
  • You can also make a small “quiz spinner” by adding another chopstick with an arrow shape to randomly select an angle for students to guess.
