North Carolina Standard Course of Study
NC.7.NS. The Number System
Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
NC.7.NS.1. Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers, using the properties of operations, and describing real-world contexts using sums and differences.
NC.7.NS.2. Apply and extend previous understandings of multiplication and division.
NC.7.NS.2.a. Understand that a rational number is any number that can be written as a quotient of integers with a non-zero divisor.
NC.7.NS.2.b. Apply properties of operations as strategies, including the standard algorithms, to multiply and divide rational numbers and describe the product and quotient in real-world contexts.
NC.7.EE. Expressions and Equations
Solve real-world and mathematical problems using numerical and algebraic expressions, equations, and inequalities.
NC.7.EE.4. Use variables to represent quantities to solve real-world or mathematical problems.
NC.7.EE.4.a. Construct equations to solve problems by reasoning about the quantities.
NC.7.EE.4.a.1. Fluently solve multistep equations with the variable on one side, including those generated by word problems.
NC.7.EE.4.a.2. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.
NC.7.EE.4.b. Construct inequalities to solve problems by reasoning about the quantities.
NC.7.EE.4.b.2. Compare an algebraic solution process for equations and an algebraic solution process for inequalities.
