Number Line: Comparing and Ordering Integers LESSON 1

Number Line Origin Positive NumbersNegative Numbers

Number Sets Counting Numbers/Natural Numbers: numbers we say ◦{1, 2, 3, 4, 5, …} Whole Numbers: The counting numbers and zero ◦{0, 1, 2, 3, 4, …} Integers: The whole numbers and their opposites ◦{…, -2, -1, 0, 1, 2…}

Absolute Value The distance of that number from zero always positive

Comparison Symbols Less than Greater than Equal Less than or equal to Greater than or equal to

Examples Ex. 3 Graph the numbers in this sequence on a number line. {…, -4, -2, 0, 2, 4…} Ex. 4 Graph two numbers that are 5 units from zero.
