In this lesson, students learn about algebraic expressions using all four operations—how to build them to represent real-world values and measurements, how to evaluate them, and how to rewrite and simplify them. Students practice thinking flexibly with expressions containing unknowns (variables) and practice converting between verbal and mathematical algebraic expressions.


In this video, we build an algebraic expression using the variable x to represent the area of a professional basketball court. We show how to setup the expression to make the multiplication simpler and then evaluate the expression by substituting the number for the unknown.
