Creating a coordinate geometry working model with a four-part partition that can hide and open using cardboard and color paper is a great way to visually teach and understand the concept of coordinate planes. Here’s a step-by-step guide on how to create this interactive model:

### Materials Needed:

- Cardboard (for the base and partitions)
- Color paper (for decoration and labeling)
- Ruler
- Scissors or craft knife
- Glue or hot glue gun
- Markers or pens
- Brass fasteners (for creating rotating partitions)
- Protractor (for measuring angles)

#### 1. Prepare the Base and Coordinate Plane

**Base Preparation**:- Cut a large square piece of cardboard to serve as the base. This will represent the coordinate plane.
- Cover the base with white paper or color paper to create a clean background.

**Draw the Coordinate Plane**:- Using a ruler and marker, draw the x-axis and y-axis on the base. Ensure the lines intersect at the center of the square to form the origin (0,0).
- Label the quadrants I, II, III, and IV in their respective positions.

#### 2. Create the Four-Part Partitions

**Partition Pieces**:- Cut four equal rectangular pieces of cardboard. These will be used to create the partitions that can hide and open.
- Cover each piece with color paper for decoration.

**Attach Partitions**:- Place each partition piece on one quadrant of the coordinate plane.
- Use brass fasteners to attach the partitions to the base at the intersection point (origin). This will allow the partitions to rotate and open/close.
- Ensure the partitions can rotate freely without obstruction.

#### 3. Design the Interactive Features

**Mark the Grid**:- Draw a grid on each partition piece using a ruler and marker. This will help in plotting points and understanding the coordinate geometry.

**Label the Axes**:- Label the x-axis and y-axis on each partition piece to ensure clarity when the partitions are open.

#### 4. Assemble the Model

**Fix the Partitions on the Base**:- Attach the partitions securely using the brass fasteners. Ensure that they can be easily rotated to open and close, hiding or revealing the quadrants.

**Add Handles**:- Create small handles using cardboard or color paper and attach them to the outer edge of each partition. This will make it easier to rotate the partitions.

#### 5. Demonstrate Coordinate Geometry

**Plot Points**:- Use markers to plot points on the grid. You can use small stickers or dots to represent points on the coordinate plane.
- Label the points with their coordinates (e.g., A(3,2)).

**Show Quadrants**:- Open and close the partitions to hide and reveal different quadrants. This helps in understanding how points are located in different quadrants based on their coordinates.

### Final Touches:

**Decorate the Model**:- Add labels and decorations to make the model more attractive and informative. You can use different colors for each quadrant to enhance visual distinction.

**Interactive Elements**:- Add more interactive elements like movable points or additional grid lines if desired.

By following these steps, you can create an effective and interactive working model that demonstrates the principles of coordinate geometry.
