# algebraic expressions working model math’s project

Algebraic expressions are mathematical phrases that include numbers, variables, and operations (such as addition, subtraction, multiplication, and division).

These expressions can represent relationships, quantities, or operations in a concise and symbolic manner.

Understanding algebraic expressions is fundamental in algebra and provides a powerful tool for solving problems and expressing mathematical relationships.

### Working model for algebraic expressions making

Creating a working model for algebraic expressions with a cardboard box and rotating square holes is a creative way to represent mathematical concepts.

## Materials Needed:

1. Cardboard box
2. Ruler
3. Pencil
4. Craft knife or scissors
5. Colored markers or paper
6. Brass fasteners (optional)
7. Small wooden dowel or pencil (for rotation)
8. Glue
9. Paper or index cards

## Video Steps by Steps Algebraic Expressions Working Model:

1. Prepare the Cardboard Box:
• Start with an empty cardboard box. Cut off the flaps at the top and bottom so that you have an open box.
2. Create Two Square Holes:
• On opposite sides of the box, draw two equal-sized squares. These squares will act as the rotating windows.
• Cut out the squares using a craft knife or scissors.
3. Design Algebraic Expressions:
• Write algebraic expressions on colored paper or index cards. Use variables (x, y, etc.) and constants to create expressions.
• For example, you can create expressions like “2x + 3” or “4y – 1.”
4. Attach Expressions to Rotating Mechanism:
• Cut out the squares or rectangles that contain the algebraic expressions.
• If you’re using index cards, you can attach them to the cardboard box near the rotating windows using glue or brass fasteners.
5. Create the Rotating Mechanism:
• Cut a small wooden dowel or use a pencil as a rotating axis. This axis will be placed through the center of the squares on the box.
• Attach the wooden dowel or pencil to the box, going through the center of the squares. You can secure it with glue or use brass fasteners for added stability.
