| 6.EE.1. Write and evaluate numerical expressions involving whole-number exponents. | Common Core Mathematics | Grade 6 | Expressions And Equations | Apply And Extend Previous Understandings Of Arithmetic To Algebraic Expressions |
| 6.EE.2. Write, read, and evaluate expressions in which letters stand for numbers. | Common Core Mathematics | Grade 6 | Expressions And Equations | Apply And Extend Previous Understandings Of Arithmetic To Algebraic Expressions |
| 6.EE.3. Apply the properties of operations to generate equivalent expressions. | Common Core Mathematics | Grade 6 | Expressions And Equations | Apply And Extend Previous Understandings Of Arithmetic To Algebraic Expressions |
| 6.EE.4. Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for. | Common Core Mathematics | Grade 6 | Expressions And Equations | For Example, Apply The Distributive Property To The Expression 3 (2 + X) To Produce The Equivalent Expression 6 + 3X; Apply The Distributive Property To The Expression 24X + 18Y To Produce The Equivalent Expression 6 (4X + 3Y); Apply Properties Of Operations To Y + Y + Y To Produce The Equivalent Expression 3Y |
| 6.EE.5. Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true. | Common Core Mathematics | Grade 6 | Expressions And Equations | Reason About And Solve One-Variable Equations And Inequalities |
| 6.EE.6. Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set. | Common Core Mathematics | Grade 6 | Expressions And Equations | Reason About And Solve One-Variable Equations And Inequalities |
| 7.EE.4. 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. | Common Core Mathematics | Grade 7 | Expressions And Equations | Solve Real-Life And Mathematical Problems Using Numerical And Algebraic Expressions And Equations |
