Domain - The Number System
Cluster - Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
[7.NS.A.1.d] - Apply properties of operations as strategies to add and subtract rational numbers.
[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.
[7.NS.A.3] -
Solve real-world and mathematical problems involving the four operations with integers and other rational numbers.
