Section 1.4, “Compare and Order Integers” Integer- the set of whole numbers and their opposites “To be an Integer or Not to be an Integer” ¾ -½ +6 +7 -4 -32 Integers Integers are divided into three categories: Positive numbers Negative numbers Zero -5 -4 -3 -2 -1 0 1 2 3 4 5 negative zero positive Creating a Number Line … Fold your paper in half left to right. Fold your paper top to bottom. At the center mark ZERO. Make a tick mark every ½ inch on the number line. Ordering Integers Order the following integers from least to greatest. 0, -6, 5, -3, 4, 2 -5 -4 -3 -2 -1 0 1 2 3 4 5 negative -6, -3, 0, 2, 4, 5 zero positive Ordering Integers Order the following integers from greatest to least. -3, 6, 2, 0, 1, -2 -5 -4 -3 -2 -1 0 1 2 3 4 5 negative zero positive 6, 2, 1, 0, -2, -3 OPPOSITES -5 -4 Two numbers that are the same distance from ZERO. -3 -2 negative -1 0 zero What is the opposite of -3? 1 2 3 4 5 positive Opposite of -3 = 3 ABSOLUTE VALUE -5 -4 The distance a number is away from ZERO. Distance is always “positive.” -3 -2 negative -1 0 1 2 zero What is the absolute value of -4? or |-4| What is |4| ? 3 4 5 positive |-4| = 4 |4| = 4 Guided Practice Text p. 25, #1-15 all Homework Text p.25-26, #18-58 even Mid-Chapter Quiz Monday (Sections 1.1-1.4) “Opposites Poster” Pretend you have to teach a lesson on integers to a 4th grade class. Create a poster on construction paper, about opposites. Include at least seven picture examples of opposites things. Include 10 examples of opposite integers.
