During this unit students will…
 Apply and extend prior operations with rational numbers.
By the end of this unit students will be able to…
7.NS.1 
 Fluently add, subtract, multiply and divide rational numbers.
 Solve real-world and mathematical problems rational numbers.
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.
7.NS.1a 
Describe situations in which opposite quantities combine to make 0.
7.NS.1.bo
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 real-world contexts.
7.NS.1c o
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.
7.NS.1d o
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.
7.NS.2a o
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 realworld contexts.
7.NS.2b o
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.2c
Apply properties of operations as strategies to multiply and divide rational numbers
7.NS.2d o
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.
These suggested learning targets were determined based on the intentions of the CCSS and/or NCES. Teachers
will need to add the criteria for success in order to create outcome-based targets.

Teachers determine the learning plan while reflecting on the range of abilities, styles, interests and needs of
students. How will the work be personalized and differentiated in order to achieve the desired learning targets?
