## Lesson: Writing and Solving Equations

Introducing the Concept

Translating expressions and equations from numbers and symbols to words is the first step in writing equations. A more challenging aspect is having students analyze a word problem and generate expressions and equations from words or word phrases themselves. Students may have difficulty with the variety of information presented in a word problem. Work with the class to isolate the specific information needed to write an expression.

**Materials:** overhead projector or chalkboard

**Preparation:** none

**Prerequisite Skills and Concepts:** Students should be familiar with words that indicate operations as well as numbers. They should also have a working knowledge of the use of parentheses in an expression as well as the process of simplifying.

Write “**3 more flowers than**” and “**the total amount**” and “**the difference between**” and “**what is left**” on the board or overhead.
