Creating a working model to illustrate the square of a number using cardboard can be a hands-on and interactive project.

Below is a simple guide to help you make a model that demonstrates the concept of squaring numbers:

**Materials:**

- Cardboard boxes (small to medium-sized)
- Ruler
- Pencil
- Craft knife or scissors
- Colored markers or paints
- Index cards or small pieces of cardboard
- Split pins (brads)
- String or yarn
- Glue or tape

## Step by Step Square Number Working Model **:**

**Prepare the Base:**- Cut out a square piece of cardboard from a cardboard box. This will serve as the base for your model.

**Divide the Base:**- Use a ruler and pencil to divide the square base into smaller squares, creating a grid. Label each square with a number, starting from 1 and going up to the maximum number you want to demonstrate.

**Create Number Cards:**- Cut small squares from index cards or cardboard. Write one number on each card, corresponding to the numbers on the base. These cards will represent the numbers you are squaring.

**Draw Squares on Number Cards:**- On each number card, draw a square to represent the square of that number. For example, if the number is 3, draw a 3×3 square.

**Attach Number Cards to the Base:**- Use split pins (brads) to attach the number cards to the corresponding squares on the base. This allows the cards to rotate freely.

**Optional: Add a Rotating Indicator:**- Cut out an arrow or pointer from cardboard and attach it to the center of the base using a split pin. This arrow can be rotated to point to different numbers, allowing you to focus on one square at a time.
