# Lesson Plan: Powers and Exponents for Rational Numbers Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify the base and exponent in power formulas, write them in exponential and expanded forms, and evaluate simple powers.

#### Objectives

Students will be able to

• understand that a power is a repeated multiplication,
• identify the base and exponent of a power,
• write a power in expanded form (repeated multiplication) and vice versa,
• evaluate powers of integers and rational numbers with positive integer exponents,
• solve real-world problems using powers and exponents,
• simplify numerical and simple algebraic expressions by calculating the values of rational numbers raised to a positive integer power.

#### Prerequisites

Students should already be familiar with

• multiplication, division, addition, and subtraction of integers and rational numbers.

#### Exclusions

Students will not cover

• laws of exponents,
• negative and zero exponents.
