MAFS.7.NS.1.1
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.
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.
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.

Learning Targets and Learning Criteria |
---|
Students are successful when they can…
b.
- define additive inverse as a rational number added to its negative which results in a sum of zero.
- define the direction of the distance on a number line based on the sign of the addend. Negative
is left/down and positive is right/up.
- define the sum of two rational numbers as the distance one addend is away from the total by the
absolute value of the other addend. Example: -4 + -3 = -7
- solve real world problems involving adding rational numbers
c.
- calculate the distance between two rational numbers by finding the absolute value of
their difference.
- compare subtracting rational numbers to adding the additive inverse. Example: -4 – (-3) = -4 + 3
- prove that the distance between two rational numbers is equal to the absolute value of their
difference. Example: the distance between -4 and -1 on a number line equals |-4 – (-1)| = 3
- solve real world problems describing involving subtracting rational numbers. Example: How many degrees cooler is -4?
