In this lesson, we will learn 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.
