Lesson 1
- 1. Lesson 1 Obj: Students will use a number line to compare and order integers.
- 2. Notes Natural (counting) numbers = (1, 2, 3, 4, …) Whole numbers = (0, 1, 2, 3, 4, …) Integers = (…-4, -3, -2, -1, 0, 1, 2, 3, 4, …) Questions: Do natural numbers have a 0? Do whole numbers have negative numbers? Is zero an integer? Is zero a counting number? Why does a number line have arrows at each end? Why do you think 0 is called the origin?
- 3. Notes • Absolute value – how far a number is away from 0 on a number line. Example: 3 = −3 = 6 = −6 = 100 = −2000 = 57 = −1 =
- 4. Practice • Arrange these integers in order from least to greatest. -3, 3, 0, 1 2, -1, 4, 0 0, -2, 5, -7 • Compare < , >, = -3 -1 −3 −1 2 -5 -7 0 −2 −3 6 -10
