Students understand that an equation is a statement of equality between two expressions. Students build an algebraic expression using the context of a word problem and use that expression to write an equation that can be used to solve the word problem. Students are asked to substitute a number for the variable to check whether it is a solution to the equation. This lesson focuses on students building an equation that can be used to solve a word problem.
