  1. Comparing and Ordering Positive and Negative Numbers Lesson 6.1 Page 218-220

  2. 10/06/08 10/06/08 Lesson 1.2: pg. 219, # 1-6; pg. 220, # 12-17 Lesson 6.1: Comparing & Ordering Positive and Negative Numbers (pg. 218-220) Standards: 12R 12L

  3. CA Content Standards • Number Sense 1.1***: We compare and order positive and negative fractions, decimals, and mixed numbers and place them on a number line. • Mathematical Reasoning 1.1: We analyze problems by identifying relationships, distinguishing relevant from irrelevant information, sequencing and prioritizing information, and observing patterns.

  4. 10/06/08 10/06/08 Lesson 1.2: pg. 219, # 1-6; pg. 220, # 12-17 Lesson 6.1: Comparing & Ordering Positive and Negative Numbers (pg. 218-220) Standards: Vocabulary: 12R 12L

  5. Vocabulary: INTEGERS • The set of positive whole numbers, their opposites, and zero. (Ex: -2, -1, 0, +1, +2) -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

  6. Vocabulary: OPPOSITES • Pairs of numbers that are the same distance on a number line from zero. (Ex: -7 & +7)

  7. Vocabulary: POSITIVE NUMBERS • Numbers whose value is greater than zero. (Ex: +4 & +9)

  8. Vocabulary: NEGATIVE NUMBERS • Numbers whose value is less than zero. (Ex: -3 & -8)

  9. Vocabulary: ABSOLUTE VALUE • The distance from zero to an integer on the number line. • Absolute values are always neutral (neither + nor -).

  13. Parts of a Number Line Bigger numbers are to the RIGHT Smaller numbers are to the LEFT

  14. Place +5, -4, +2, 0, and -2 on a number line. Then write them in order from least to greatest. REMEMBER… Bigger numbers are to the RIGHT Smaller numbers are to the LEFT From least to greatest: -4, -2, 0, 2, 5 Example 1.

  15. Place +2, -0.5, 0, -3, and + 1.75 on a number line. Then write them in order from least to greatest. REMEMBER… Bigger numbers are to the RIGHT Smaller numbers are to the LEFT From least to greatest: -3, -0.5, 0, +1.75, +2 Example 2.

  17. Write the absolute value and the opposite of -4. -4 Absolute value (always neutral) = 4 Opposite = +4 Example 3.

  18. Write the absolute value and the opposite of +386, 942. +386,942 Absolute value (always neutral) = 386,942 Opposite = -386,942 Example 4.

  20. The Moral of the Story • To order positive and negative numbers, use their position on the number line to assess their relative value.
