Introduction to Writing Algebraic Expressions may be as close as some middle school students come to cracking secret codes. There is a certain intrigue to representing an entire sentence as 4 simple symbols. In the activity, Introduction to Writing Algebraic Expressions, students will begin by reviewing the meaning of a variable. Is there a difference between a question mark and the letter n to represent a missing value? Students will have the opportunity to make these connections as they progress through the beginning of this activity.
Students will then combine their knowledge of variables and operations to form algebraic expressions. They will match phrases to algebraic expressions, write algebraic expressions to represent written phrases, and represent real life situations as algebraic expressions. This activity provides students with a great introduction to writing algebraic expressions that they will use to solve numerous mathematics problems in the future.
