Common Core Math: Grade 7: Number System
In seventh grade, students add, subtract, multiply and divide rational numbers, which include fractions, decimals and negative numbers. Students understand negative numbers as the opposites, or additive inverses, of positive numbers and understand that subtraction is equivalent to addition with an additive inverse. Students use number lines to visualize addition and subtraction with negative numbers and explore patterns in multiplication and division with negative numbers.
