Math 6 Unit Test #1 Study Guide: Integers Name: Integer: a counting number, zero, or the opposite of a counting number […-2, -1, 0, 1, 2…] NOT a fraction, decimal, or percent -2.5, ¾ , 35% Integers are used to represent everyday situations in word problems. positive situations negative situations above below deposit withdraw rise fall gain loss after before increase decrease Practice Use your knowledge of integers to answer the following questions. 1. Circle the numbers below that ARE integers. 2.3 ⅜ 1 -4 3.3333 -0.23 45% What makes a number NOT an integer? ______________ _______________________________________________ 2. Write the following phrases numerically. A loss of 10 yards ____________________ 6 inches taller ____________________ An altitude of 1500 feet ____________________ 16 units to the left of zero on the number line ____________________ A profit of $25 ____________________ A debit of $40 ____________________ A credit of $65 ____________________ 3 strokes under par ____________________ 10 3. Draw a comparison sign to complete each number statement. -15 ____ 9 30 ____ -12 -3 ____ -4 20 ____ -7 -18 ____ 5 -11 ____ -8 When comparing two negative numbers, the number closer to zero is always greater. Answer the following questions by looking at the number line. E -6 -5 F -4 -3 -2 G -1 0 1 2 3 H I 4 5 6 4. At what point do you find E? _____ 5. At what point do you find G? _____ 6. What is the opposite of F? _____ 7. Circle the set of integers that is in order from least to greatest. –7, –10, 1, 6 –12, –4, 4, 8 –1, 13, –17, 9, –22, –15, 5, 0 8. Which situation is represented by -20? a profit of $20 a withdrawal of $20 20 laps ahead of the swimmer 20 feet above sea level Absolute Value Absolute Value: the number of units a number is away from zero. –4says “the absolute value of negative four” +5says “the absolute value of positive five” Remember positive numbers are ALWAYS greater than negative numbers. Practice Find the absolute value of each number. –2 4 –5 +2 0
