Study Notes
Number lines
- Fill in the missing numbers on the number lines
- number line a) -42, -39, -36, -33, -30, -27, -24, -21, -18, -15, -12, -9, -6, -3, 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42
- number line b) -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5
Integers and Number Lines
- Integers are whole numbers that can be positive, negative, or zero
- Representing numbers on a number line:
- Positive integers are placed to the right of zero
- Negative integers are placed to the left of zero
- Scenario a): Miss Anderson set the temperature in her classroom to 20 above zero.
- Integer: 20
- Number line representation: A horizontal line segment starting at 20 on the number line (between 10 and 30).
- Scenario b): The submarine went 60 meters below sea level.
- Integer: -60
- Number line representation: A horizontal line segment starting at -60 on the number line (between -70 and -50).
- Scenario c): Aaron owed his sister $25.00.
- Integer: -25
- Number line representation: A horizontal line segment starting at -25 on the number line (between -30 and -20).
Representing Scenarios as Integers
- Positive integers represent quantities like money earned, height above sea level, and temperature above zero.
- Negative integers represent quantities like money owed, depth below sea level, and temperature below zero.
Ordering Integers
- Integers are ordered from least to greatest on a number line, with negative numbers to the left of zero and positive numbers to the right.
- When ordering integers, consider their distance from zero. For example, -8 is less than -4, because -8 is farther from zero than -4.
Additive Inverses
- The additive inverse of a number is the number that, when added to the original number, results in zero.
- The additive inverse of a positive number is its negative counterpart, and vice versa.
