5.OA.1. Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.||Common Core Mathematics||Grade 5||Operations And Algebraic Thinking||Write And Interpret Numerical Expressions|||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.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.1. Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.||Common Core Mathematics||Grade 7||Expressions And Equations||Use Properties Of Operations To Generate Equivalent Expressions|||7.EE.2. 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. For example, a + 0.05a = 1.05a means that “”increase by 5%”” is the same as “”multiply by 1.05.””||Common Core Mathematics||Grade 7||Expressions And Equations||Use Properties Of Operations To Generate Equivalent Expressions
