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:

Cardboard (for the base and circle structures)

Color paper (for representing circles and details)

Compass or any circular object to draw circles

Scissors

Glue or double-sided tape

Marker pens or sketch pens

Ruler (optional)

Step-by-step instructions:

Base:

Cut a rectangular or square piece of cardboard to serve as the base for the circle definitions model.

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.

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.

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.

Drawing Radii and Diameter:

Use a ruler (optional) to draw radii and a diameter for some circles.

Extend lines from the center of the circle to the edge to represent radii.

Draw a line passing through the center and touching both ends of the circle to represent the diameter.

Decorating the Model:

Use markers or color paper to decorate the circle definitions model and add more details to make it visually appealing.

Now, you have a simple 3D working model of circle definitions made from cardboard and color paper. This model can be an excellent visual aid to learn about various circle terms and properties, such as center, radius, diameter, circumference, chord, secant, and tangent.
