Unit 4, Lesson 5# Exponents

EngageNY 45 min(s)

In this lesson, students use new terminology (base, squared, and cubed) and practice moving between exponential notation, expanded notation, and standard notation. Students understand that a base number can be represented with a positive whole number, positive fraction, or positive decimal and that for any number a, a^m is defined as the product of m factors of a. The number a is the base, and m is called the exponent or power of a. Use whole number exponents to denote powers of 10.
