Grade 7 Math: Number System
Grade Seven - Grade 7 Mathematics - Grade 7 ELA: English Language Arts - Seventh Grade Vocabulary
 
 
Apply and extend previous understandings of operations with fractions.
 
CCSS.MATH.CONTENT.7.NS.A.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.
 
 
CCSS.MATH.CONTENT.7.NS.A.1.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.
 
 
 
CCSS.MATH.CONTENT.7.NS.A.1.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 real-world contexts.
 
 
CCSS.MATH.CONTENT.7.NS.A.1.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.
 
 
CCSS.MATH.CONTENT.7.NS.A.1.D - Apply properties of operations as strategies to add and subtract rational numbers.
 
 
CCSS.MATH.CONTENT.7.NS.A.2 - Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
 
 
CCSS.MATH.CONTENT.7.NS.A.2.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.
 
 
CCSS.MATH.CONTENT.7.NS.A.2.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.
 
 
CCSS.MATH.CONTENT.7.NS.A.2.C - Apply properties of operations as strategies to multiply and divide rational numbers.
 
 
CCSS.MATH.CONTENT.7.NS.A.2.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.
 
 
CCSS.MATH.CONTENT.7.NS.A.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.)
