In this post we write about making of geometric shapes formulas model making – maths tlm working model

Creating a geometric shapes formulas model using cardboard and color paper is a great way to visualize and understand the formulas for different shapes.

Let’s build a simple model that represents various geometric shapes with their corresponding formulas.

## Materials needed:

1. Cardboard (for the base and structures)
2. Color paper (for representing different shapes and formulas)
3. Scissors
4. Glue or double-sided tape
5. Marker pens or sketch pens

Shapes and their corresponding formulas to include in the model:

1. Square:
• Formula: Area = side × side
• Formula: Perimeter = 4 × side
2. Rectangle:
• Formula: Area = length × width
• Formula: Perimeter = 2 × (length + width)
3. Circle:
• Formula: Area = π × radius^2
• Formula: Circumference = 2 × π × radius
4. Triangle:
• Formula: Area = (base × height) / 2
• Formula: Perimeter = side1 + side2 + side3
5. Parallelogram:
• Formula: Area = base × height
• Formula: Perimeter = 2 × (side1 + side2)

## Step-by-step video instructions:

1. Base:
• Cut a large rectangular or square piece of cardboard to serve as the base for the model.
2. Shapes Representation:
• Use color paper to create representations of each geometric shape (square, rectangle, circle, triangle, parallelogram).
• Cut out shapes from color paper based on their respective formulas.
3. Labeling:
• Write the name of each shape on the color paper representing it.
• Write the formulas for area and perimeter (or circumference) next to each shape.
4. Placement on the Base:
• Arrange the shapes with their formulas neatly on the base, leaving enough space between them.
5. Decorating the Model:
• Use markers or color paper to decorate the model and add more details to make it visually appealing.

Now, you have a geometric shapes formulas model using cardboard and color paper. This model visually represents various geometric shapes along with their corresponding area and perimeter (circumference) formulas.
