Exploring the Number Line: Understanding Negative and Positive Numbers

Learning Objective

At the end of the lesson you will be able to understand the number line and the position of negative and positive numbers, and compare them using inequality symbols.

What do you already know about negative and positive numbers?

Introduction to the Number Line

The number line is a visual representation of numbers extending infinitely in both positive and negative directions.

Positive and Negative Numbers

Positive numbers are greater than zero, while negative numbers are less than zero.

Position of Negative and Positive Numbers

Negative numbers are to the left of zero on the number line, and positive numbers are to the right.

Comparing Negative and Positive Numbers

Negative numbers are less than positive numbers. We use inequality symbols () to compare them.

Interactive Activity: Number Line Exploration

Engage in a hands-on activity where students place negative and positive numbers on a large number line.

Using Inequality Symbols

Inequality symbols () are used to compare negative and positive numbers. < means less than, and > means greater than.

Practice Time: Comparing Numbers

Students will solve practice problems by comparing negative and positive numbers using inequality symbols.

Review and Conclusion

Summarize the key concepts learned about the number line, negative and positive numbers, and comparing them using inequality symbols.
