# how to make working model to represent the square roots – maths project

Creating a working model to represent the square roots using cardboard, color paper, and a table fan format (with 10 blades) can be a fun and educational project.

Here’s a step-by-step guide to making this model:

### Materials Required:

1. Cardboard
2. Color paper (different colors)
3. Table fan (or a small motor with a propeller)
4. Markers or pens
5. Glue or tape
6. Scissors
7. Ruler
8. Compass or circular object for tracing

### Step by Step Video Instructions:

#### Step 1: Prepare the Fan Blades

1. Create the Blades: Cut 10 identical fan blades from the cardboard. Each blade should be around the same size. You can make each blade around 4-5 inches in length.
2. Label the Blades: Using markers or pens, label each blade with numbers from 1 to 10.
3. Decorate the Blades: Cover each blade with color paper, using a different color for each number if possible. This makes it visually appealing and helps distinguish each blade.

#### Step 2: Assemble the Fan

1. Base of the Fan: Cut a circular base from the cardboard to attach the fan blades. This base will be the central hub of the fan.
2. Attach the Blades: Evenly space the 10 blades around the circular base and attach them using glue or tape. Ensure they are securely fixed and evenly distributed.

#### Step 3: Add the Square Root Representations

1. Square Root Labels: Cut small rectangular pieces from the color paper to use as labels. Write the square root of each number (from 1 to 10) on these labels. For example, √1, √2, √3, etc.
2. Attach the Labels: Glue or tape each square root label to the corresponding blade. Ensure each blade is properly labeled with its square root value.

#### Step 5: Create the Display

1. Display Base: Create a stable base for your model using cardboard. This will hold the motor and fan assembly.
2. Mount the Motor: Secure the motor to the display base. Ensure it is stable and the fan blades can rotate freely without obstruction.

#### Step 6: Final Touches

1. Decorate the Base: Use color paper and markers to decorate the base. You can add labels, designs, or any other decorative elements to make it more attractive.
2. Testing: Turn on the motor and ensure the fan blades rotate smoothly. The labels should be easily readable as the blades spin.

(Each number represents a blade with its corresponding square root label)

### Explanation

When the fan blades rotate, each blade representing a number from 1 to 10 and labeled with its square root will be visible.

This model visually demonstrates the concept of square roots in a dynamic and engaging manner. As the fan spins, students can see the direct correlation between each number and its square root, providing a hands-on learning experience.

This project combines creativity and learning, providing an interactive way to understand square roots.
