# how to make circle maths working model – geometry working model

In this post we write about making of the circle maths working model – geometry working model | circle definitions using cardboard

Creating a working model to illustrate circle definitions using cardboard and color paper can be an interactive and educational project to understand various aspects of circles.

Let’s build a simple 3D model to represent circle definitions.

Materials needed:

1. Cardboard (for the base and circle structures)
2. Color paper (for representing circles and details)
3. Compass or any circular object to draw circles
4. Scissors
5. Glue or double-sided tape
6. Marker pens or sketch pens
7. Ruler (optional)

Step-by-step instructions:

1. Base:
• Cut a rectangular or square piece of cardboard to serve as the base for the circle definitions model.
2. Circle Structures:
• Using a compass or any circular object, draw circles of different sizes on color paper. You can create multiple circles of various radii.
• Cut out the circle shapes from the color paper.
3. Definitions and Labels:
• Write definitions or terms related to circles on small pieces of color paper.
• For example, you can have labels like “Center,” “Radius,” “Diameter,” “Circumference,” “Chord,” “Secant,” “Tangent,” etc.
4. Placement of Circles and Labels:
• Arrange the circle shapes on the base, representing circles of different sizes and positions.
• Place the corresponding definitions or labels near the relevant circles.
