MD.MA.7.NS. The Number System (NS)
Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
7.NS.2. Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational number.
7.NS.2b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then: −(p/q) = -p/q = p/-q. Interpret quotients of rational numbers by describing real-world contexts.
7.NS.2b.2. Ability to apply and extend knowledge of addition and subtraction of integers (i.e., two color counters, arrows on a number line) to extend to multiplication and division.
7.NS.2b.3. Ability to use patterns and concrete models to devise a general rule for dividing integers: −(p/q) = -p/q = p/-q.
7.NS.2c. Apply properties of operations as strategies to multiply and divide rational numbers.
7.NS.2c.1. Ability to identify and apply the following properties: Distributive Property; Associative Properties; Commutative Properties; Identity Properties.
7.NS.3. Solve real-world and mathematical problems involving the four operations with rational numbers. (Note: Computations with rational numbers extend the rules for manipulating fractions to complex fractions.)
7.NS.3.2. Ability to apply knowledge of Order of Operations.
