# Q1, W7: October 12th – 16th Regular Math

Teacher Felicia Taylor Regular Math 7th 7 Focus 1: The Number System
Standard(s) Taught

b.

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?
