Study Guide: Number Line

A number line is a visual representation of numbers in order, typically starting from 0 and extending infinitely in both the positive and negative directions. It's a useful tool for understanding the relationship between numbers and their positions relative to each other.

Key Concepts:

1. Positive numbers: Numbers greater than 0 are represented to the right of 0 on the number line.
2. Negative numbers: Numbers less than 0 are represented to the left of 0 on the number line.
3. Integers: Whole numbers, both positive and negative, as well as 0, are all represented on the number line.
4. Fractions and decimals: These can also be represented on the number line. For example, 1/2 would be located halfway between 0 and 1 on the number line.
5. Ordering and comparing numbers: The number line can be used to compare numbers and determine their relative positions.
6. Adding and subtracting: The number line can be used to visualize addition and subtraction.

Activities:

• Locating numbers: Practice identifying the position of specific numbers on the number line.
• Comparing numbers: Given two numbers, determine which is greater or less by using the number line.
• Adding and subtracting: Use the number line to add and subtract numbers, and visualize the process.
