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.

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 -).

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
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
Place +2, -0.5, 0, -3, and 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.
