Students will solve real-world and mathematical problems involving the four operations with rational numbers. They will learn
to add, subtract, multiply, and divide with integers and extend that knowledge to include rational numbers .
7.NS.1 Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent
addition and subtraction on a horizontal or vertical number line diagram.
a. Describe situations in which opposite quantities combine to make 0. For example, a hydrogen atom has 0 charge because its two
constituents are oppositely charged.
b. Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is
positive or negative.
Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing realworld contexts.
c. Understand subtraction of rational numbers as adding the additive inverse, p – q = p + (–q). Show that the distance between two
rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
d. Apply properties of operations as strategies to add and subtract rational numbers.
7.NS.2 Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational
numbers.
a. Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy
the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for
multiplying signed numbers. Interpret products
of rational numbers by describing real-world contexts.
b. 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.
c. Apply properties of operations as strategies to multiply and divide rational numbers.
d. Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or
eventually repeats

7.NS.3 Solve real-world and mathematical problems involving the four operations with rational numbers. (Computations with
rational numbers extend the rules for manipulating fractions to complex fractions.)
7.EE.3 Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form
(whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations as strategies to calculate with
numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation
and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her
salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is
27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact
computation.
