Dear Parents,
Tomorrow we will begin Chapter 3: Integers. In this chapter, your child will learn how to
add, subtract, multiply, and divide integers. Below you will find key vocabulary words from
the chapter and activities you can do with your child at home to support the mathematics we
are learning in class. If you have any questions or concerns about this chapter or your child’s
progress, please feel free to email or call me.
Sincerely,
Annette Blue
Math Teacher
Chapter 3: Integers Vocabulary
Absolute value -
the distance the number is from zero on a number line
Additive inverse -
two integers that are opposites; the sum of an integer and its additive
inverse is zero
Graph -
the process of placing a point on a number line or on a coordinate
plane at its proper location
Integer -
any number from the set {…, -4, -3, -2, -1, 0, 1, 2, 3, 4, …} where …
means continues without end
Negative integer -
an integer that is less than zero; negative integers are written with a - sign
Opposites -
two integers are opposites if they are represented on the number line by
points that are the same distance from zero, but on opposite sides of
zero; the sum of two opposites is zero
Positive integer -
an integer that is greater than zero; they are written with or without a +
sign
Zero pair -
the result when one positive counter is paired with one negative
counter; the value of a zero pair is zero

Hands-On Activity
Materials: positive and negative counters
 Combine a set of 2 positive counters and 4 positive counters. Find the total number of
counters. 2 + 4 = 6
 Combine a set of 3 negative counters and 5 negative counters. Find the total number
of counters. -3 + -5 = -8
 Combine a set of 6 positive counters and 1 negative counter. Remove all pairs of
positive and negative counters. Find the total number of remaining counters.
6 + -1 = -5
 Continue this activity with different numbers of counters.
On-line Activity
Find a map of the world with latitude and longitude lines marked.
 Research how positions on Earth are described using degrees of latitude and degrees of
longitude.
 Compare and contrast lines of latitude and lines of longitude with the coordinate plane.
