# algebraic identities working model – math’s project – tlm – diy | DIY pandit

Creating a working model to demonstrate algebraic identities using cardboard and two holes can be an interesting and visual way to showcase mathematical concepts.

Here’s a simple DIY project for an algebraic identities working model:

## Materials Needed:

1. Cardboard
2. Ruler
3. Pencil
4. Scissors
5. String or yarn
6. Markers
7. Colored paper
8. Glue or tape
9. Compass
10. Brass fasteners (optional)

## Steps to Create the Algebraic Identities Working Model:

Step 1: Cut Cardboard:

• Cut a large piece of cardboard to serve as the base for your working model.

Step 2: Draw Circles:

• Use a compass to draw two circles on the cardboard. These will represent the holes.

Step 3: Cut Holes:

• Cut out the circles to create the holes in the cardboard.

Step 4: Label the Circles:

• Label each hole with a variable, such as ‘a’ and ‘b,’ to represent the algebraic expressions.

Step 5: Create Flaps:

• Cut rectangular flaps on the cardboard around each hole, leaving enough space to write or attach the algebraic expressions.

Step 6: Write or Attach Expressions:

• Write the algebraic expressions corresponding to each identity on the flaps or attach colored paper with the expressions.

Step 7: Attach Strings:

• Cut two pieces of string or yarn, and thread them through the holes. Tie knots on the backside to secure them.

Step 8: Display and Explain:

• Set up your working model at the exhibition table.
• Pull the strings through the holes to visually demonstrate the algebraic identities.

Step 9: Optional – Brass Fasteners:

• Instead of string, you can use brass fasteners to attach the expressions to the holes, allowing for easy rotation.

Explanation:

• During your exhibition, explain each algebraic identity and how pulling the strings or rotating the expressions visually demonstrates the validity of the identities.

This working model provides a tangible representation of algebraic identities, making it an engaging and interactive display for a math project or exhibition. It allows students and visitors to physically manipulate the expressions, enhancing their understanding of algebraic concepts.
