= =  **Expanded Notation and Scientific Notation**

=**Standard 1:** = Students will expand number sense to include operations with rational numbers.

**Objective 1:** Represent rational numbers in a variety of ways  a. Recognize a rational number as a ratio of two integers, a to b, where b is not equal to zero.  b. Change whole numbers with exponents to standard form (e.g., 2 4 =16) and recognize that any non-zero whole number to the zero power equals 1 (e.g., 9 0 = 1).  c. Write a whole number in expanded form using exponents (e.g., 876,539 = 8 x 10 5 + 7 x 10 4 + 6 x 10 3 + 5 x 10 2 + 3 x 10 1 + 9 x 10 0 ).  d. Express numbers in scientific notation using positive powers of ten. **Lesson Plans:**  1. Expanded Notation and Scientific Notation  2. Scientific Notation
