What students learn

In this lesson, students use properties of operations to generate equivalent expressions and solve real-life and mathematical problems using numerical and algebraic expressions and equations.

  • Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.

  • Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related.

  • Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
