Lesson Plan: Writing and Evaluating Algebraic Expressions Mathematics • 7th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to write algebraic expressions and evaluate them for specific values of their variables.
Students will be able to
- write an algebraic expression, using one or more basic operations, to represent
- a geometric situation,
- a word problem,
- identify when two algebraic expressions are equivalent,
- write an algebraic expression and evaluate it for a specific value of the variable,
- solve more complex problems, such as writing and evaluating an algebraic expression involving more than one variable or writing an algebraic expression for the area of a simple shape when given the perimeter.
Students should already be familiar with
- reading and writing basic algebraic expressions without simplifications,
- simplifying algebraic expressions by combining like terms,
- using the four basic operations on positive and negative numbers.
Students will not cover
- writing and evaluating formulas,
- the product rule for exponents.
