Topic Overview

Definitive Answer: Students will extend their understanding of the number line to include rational numbers, including their placement and comparison. This includes understanding positive and negative numbers.

Imagine a thermometer or a football field. Numbers don't just go up; they can also go down or backwards! A **number line** is a straight line where every point represents a number. We're used to positive numbers (like 1, 2, 3), but numbers can also be negative (like -1, -2, -3), representing values below zero or losses. These whole numbers, positive or negative, are called **integers**. Numbers that can be written as a fraction, including integers, are called **rational numbers**. On a number line, positive numbers are to the right of zero, and negative numbers are to the left. Fractions like 1/2 or -3/4 fit right between the integers, showing parts of a whole.

Step-by-Step Examples

Example 1: On a number line, which number is located to the left of -3?
  1. Remember that on a number line, numbers get smaller as you move to the left, and larger as you move to the right.
  2. First, locate -3 on the number line. It's three units to the left of zero.
  3. To find a number to the left of -3, you need a number that is even smaller (more negative).
  4. Of the common options, -5 is further to the left of -3 on the number line, making it smaller.
✓ Answer: -5
Example 2: On a number line, where would you place the fraction 1/2?
  1. Understand that 1/2 means 'one out of two equal parts' or 'half'.
  2. Since 1/2 is a positive fraction and less than 1, it will be located between 0 and 1 on the number line.
  3. To find its exact spot, imagine dividing the space between 0 and 1 into two equal parts.
  4. The fraction 1/2 would be exactly at the halfway point between 0 and 1.
✓ Answer: Exactly halfway between 0 and 1

Tips & Tricks

  • Think of a number line like a ruler. Moving to the *left* means numbers get *smaller* (more negative). Moving to the *right* means numbers get *larger* (more positive).

Key Vocabulary

TermDefinition
Number LineA straight line where every point represents a number, extending infinitely in both positive and negative directions.
