Steps to Make Area of Circle Model

Step 1: Draw and Cut Out a Circle

1. Take your colored chart paper and use a compass to draw a circle.
   • Make sure the radius is easy to measure, like 7 cm or 10 cm.
2. Cut out the circle carefully with scissors.

Step 2: Divide the Circle into Equal Parts

1. Use a marker to draw straight lines across the circle, dividing it into equal “parts” or sectors. Start by dividing it into four parts, then eight, and finally sixteen.
   • The more parts you make, the better your model will be made.
2. Number each part.

Step 3: Rearrange the Parts

1. Take all the parts and start arranging them in an alternating pattern (up and down) to form a shape like a rectangle.
   • Place the curved edges of the slices together to create the longer sides of the rectangle.
2. Glue or tape the slices onto the cardboard base to hold them in place

Step 4: Label the Model

1. Write “Base = π × r” on one long side of the rectangle (the curved edges combined form this length).
2. Write “Height = r” on the shorter side (the radius of the circle).

Step 5: Test the Model

Now that your model looks like a rectangle, it’s easy to see how the area of a circle is derived:

Tips to Make It More Cooler

• Use bright colors to make your model attractive.
• Decorate the base with fun doodles or labels about the area of the circle.
• Add a small write-up or a key explaining the process to go along with your model.

Conclusion

Making a working model for the area of a circle is not just about getting good grades, it’s about learning a new way that sticks with your mind. By building this project, you’ll not only understand the formula better but also have fun when using it.
