In this post we write about making of the real numbers working model – maths tlm – diy

Creating a hierarchy/flowchart-style working model to represent real numbers using cardboard and color paper can be an effective way to understand the relationships between different types of real numbers.

Let’s build a simple 3D model to showcase the classification of real numbers.

Materials needed:

1. Cardboard (for the base and structures)
2. Color paper (for representing different types of real numbers)
3. Scissors
4. Glue or double-sided tape
5. Marker pens or sketch pens

Step-by-step instructions:

1. Base:
• Cut a rectangular or square piece of cardboard to serve as the base for the model.
2. Real Numbers Classification:
• Use color paper to create different shapes or rectangles for each type of real number: natural numbers, whole numbers, integers, rational numbers, and irrational numbers.
• Arrange the shapes in a hierarchical or flowchart-style manner on the base, with each type of real number placed below the one that encompasses it.
3. Natural Numbers:
• Use color paper to represent natural numbers (positive counting numbers).
• Cut out small circles or rectangles and label them with natural numbers such as 1, 2, 3, and so on.
• Arrange these shapes in the corresponding section of the model.
4. Whole Numbers:
• Use a different color paper to represent whole numbers (natural numbers plus zero).
• Cut out shapes for each whole number (including zero) and label them accordingly.
• Arrange these shapes below the natural numbers section.
5. Integers:
• Use another color paper to represent integers (whole numbers and their negatives).
• Cut out shapes for each positive and negative integer (including zero) and label them.
• Arrange these shapes below the whole numbers section.
6. Rational Numbers:
• Use a new color paper to represent rational numbers (numbers that can be expressed as fractions).
• Cut out shapes for various rational numbers (fractions) and label them.
• Arrange these shapes below the integers section.
7. Irrational Numbers:
• Use a different color paper to represent irrational numbers (numbers that cannot be expressed as fractions).
• Cut out shapes for various irrational numbers (e.g., square root of 2) and label them.
• Arrange these shapes below the rational numbers section.
8. Labeling and Details:
• Use marker pens or sketch pens to label each section with the corresponding type of real number (natural numbers, whole numbers, integers, rational numbers, and irrational numbers).
• You can add brief descriptions or explanations to the model.
9. Decorating the Model:
• Use markers or color paper to decorate the model and add more details to make it visually appealing.

ow, you have a 3D working model that represents real numbers in a hierarchy/flowchart-style using cardboard and color paper. This model can be a helpful visual aid to understand the classification of real numbers and their relationships. It’s an interactive and creative way to explore the different types of real numbers and their properties.
