RATIONAL NUMBER OPERATION LEARNING GOAL
Students will be able to apply the operations of addition and
subtraction to rational numbers, represent the operations on a
number line diagram, and solve real world problems. Students will
be able to recognize opposites and absolute value.
7.NS.1 VOCAB TERMSVocabulary Terms Definition
Negative Numbers #’s left of Zero (0), negative sign (-)
Positive Numbers #’s right of Zero, positive sign (+)
Opposites, orNumber Pairs,
are the same distance from zero but in opposite directions
Integers are ALL positive and negative WHOLE #’s
Rational Numbers Ratio of 2 integers (like fractions); Repeating or terminating decimals
Absolute Value the distance a number is from zero. Absolute value is ALWAYS Positive.
Additive Inverse What you add to a number to get zero.Ex: The additive inverse of -5 is 5 because -5 + 5 = 0The additive inverse of +5 is -5 because +5 -5 = 0

TODAY, MY LEARNING TARGET IS TO…
• Develop algorithms for subtracting integers
• Model subtraction of integers using distance and direction on a number line and a chip model
• Observe that the Commutative Property does
not hold for subtraction of rational numbers
