In this post we write about making of the maths perimeter and area formulas working model – maths tlm – diy | craftpiller
Creating a working model to represent the perimeter and area formulas for polygons using cardboard and color paper can be an excellent way to visualize and understand these concepts.
Let’s build a simple model that represents different polygons and showcases their perimeter and area formulas.
- Cardboard (for the base and structures)
- Color paper (for representing different polygons and formulas)
- Glue or double-sided tape
- Marker pens or sketch pens
Polygons to include in the model:
- Cut a large rectangular or square piece of cardboard to serve as the base for the model.
- Shapes Representation:
- Use color paper to create representations of each polygon (square, rectangle, triangle, circle, parallelogram).
- Cut out shapes from color paper based on their respective dimensions.
- Perimeter and Area Formulas:
- Write the formulas for perimeter and area on separate small rectangles of color paper for each polygon.
- For example:
- Square: Perimeter = 4 × side, Area = side × side
- Rectangle: Perimeter = 2 × (length + width), Area = length × width
- Triangle: Perimeter = side1 + side2 + side3, Area = (base × height) / 2
- Circle: Circumference = 2 × π × radius, Area = π × radius^2
- Parallelogram: Perimeter = 2 × (side1 + side2), Area = base × height
- Placement on the Base:
- Arrange the color paper representations of polygons on the base, leaving enough space for the formulas to be placed next to each polygon.
- Labeling and Details:
- Use marker pens or sketch pens to label each polygon and its corresponding formula for perimeter and area.
- 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 perimeter and area formulas working model using cardboard and color paper. This model visually represents different polygons and their respective formulas for perimeter and area
