Comparing and ordering integers

An integer is a whole number that can be positive or negative, including numbers like 12, -10, and -30,843. Fractions and decimals are rational numbers, not integers. Integers are plotted on a number line and can be ordered from least to greatest or greatest to least. The absolute value of a number represents its distance from zero on the number line and is always positive.

*An integer is the set of whole numbers and their opposites. *In other words, integers are positive (+) and negative (-) whole numbers. *Examples of integers include: 12 7 -10 -125 18 -30,843
*Fractions and decimals are NOT integers. Those are rational numbers. *Integers are whole numbers!
*Let’s look at integers on a number line. *Plot the integers 1, -9, -4, and 7 on the number line.
Compare the following integers. Use <, =, or >. Try drawing a number line to help you visualize the integers! 0 ___ 10 -5 ___ 15 5 ___ -15 0 ___ -20 -8 ___ 8 -6 ___ 6
Order the following integers from least to greatest -4 3 2 0
For this problem, we are working with -4, 3, 2, 0
*Least to greatest is left to right. *Greatest to least is right to left. *Our answer should be -4, 0, 2, 3.
*The absolute value of a number is distance it is away from zero on the number line. *We show absolute value like this: |-2| *Absolute values are always positive because the signify the distance from zero on the number line! *|-2| = 2
1. Order these temperatures from least to greatest: 0°F, 115°F, -15°F, -32°F, -40°F, 113°F 2. Compare. Use <, =, or >. 0 ___ -20 |-8| ___ 8 -6 ___ 6 3. Estimate values for points A – E. A B C D E
