Unit 5 Test: Integers—February 18
Learning Target: I can use an integer to describe a real-world situation.
Be able to write an integer for a real-world situation. Remember, if the situation refers to increasing, growing,
getting larger, or being above ground, the integer is POSITIVE. If the situation refers to decreasing, shrinking,
getting smaller, or being below ground, the integer is NEGATIVE.
Example:
A dog gained 3 pounds this year. ____________
The price of a pair of shoes decreased by $5. ____________
Mark swam 3 feet underwater ____________
A spring day with a temperature of 60 degrees ____________
Learning Target: I can find and position integers on a number line.
Be able to find positive and negative numbers on a number line. Remember that positive numbers are BIGGER
than 0, and that negative numbers are SMALLER than 0.
Put point A at -4.
Put point B at 2.
Put point C at -7
Which point is at 3? ____________
Which point is at -2? ____________
Which point is at -5? ____________
Which point is at 5? ____________
Learning Target: I can identify the opposite of an integer.
Be able to think about a number line and know what is the opposite of any integer. Remember that the
opposite of an integer is on the other side of 0. It is the same digit, but one is negative and one is positive.
What is the opposite of -3? ____________
What is the opposite of 7 ? ____________
What is the opposite of 12? ____________
What is the opposite of 0? ____________
Learning Target: I can determine the absolute value of an integer.
Remember that the absolute value is just how far a number is away from 0. You can count the number of
jumps from 0 to the integer to figure the absolute value.
What is the absolute value of 7? ____________
What is the absolute value of -8? ____________
Evaluate the expression:
Evaluate the expression:
____________
____________
Learning Target: I can compare integers.
Remember as you move to the RIGHT on a number line, the numbers get BIGGER. As you move to the LEFT on
a number line, the numbers get SMALLER.
Use < > to compare.
Name an integer that is greater than -2. _______
Name an integer that is smaller than 4. _______
Learning Target: I can find and position pairs of integers (Ordered pairs) in a
coordinate plane.
Remember, when plotting points, the first number is the X-value…it tells you to go ACROSS first. The second
number is the y-value…it tells you to go up or down second.
Position the following ordered pairs on the coordinate plane.
A
B
C
D
Identify which points are located at the ordered pairs listed.
_______

_______
Learning Target: I can determine which quadrant a point is located.
Remember that the quadrants (the four sections of the coordinate plane) are numbered 1-4 with Roman
numerals: I, II, III, IV. Quadrant I—top right. Quadrant II—top left. Quadrant III—bottom left. Quadrant IV—
bottom right.
Identify which quadrant each point is located.
