Understand Integers
What is the opposite of 21?
-21
Why are whole numbers rational numbers? Use 21 as an example.
Whole numbers are rational numbers because they can be written as fractions. 21= 21/1
What is the absolute value of |-21.8|?
What are the steps to finding the distance between two coordinates?
1. Look at the numbers
2. Label X1, Y1, X2, Y2
3. Circle the values that are different
4. Add or Subtract
What are integers? Give an example
Integers is another word for numbers.
Example: 7, 13, 21
What is the opposite of -17.83?
17.83
Plot point A on a number line. A is located at -3.
Look at the board for correct answer.
Compare using the absolute values. Which is greater?
-6.84
-6.85
|-6.84|= 6.84
|-6.85|= 6.85
so, -6.85 is greater.

What are rational numbers?
Rational Numbers are any numbers that can be written as the quotient of two integers.
Order the integers from least to greatest.
4, 12, -12, -11, 0, 21
Plot point R on the number line. Point R is located at 2.25
Look at the board for the correct answer.
Order the values from least to greatest.
|4|, |-3|, |-18|, |3.18|
|-3|, |-3.18|, |4|, |-18|
Find the distance between the two points. MUST SHOW YOUR WORK BEFORE ANSWERING.
(-1.5, 2) and (-1.5, 3.5)

What is absolute value? What is true about absolute value?
Absolute Value is the distance from 0 on a number line and it is ALWAYS positive.
Order the values from greatest to least.
21, 30, -21.9, 17.4, -6, -2
-21.9, -6, -2, 17.4, 21, 30
Look at the board for the correct answer.
Order the values from greatest to least.
|-3.2|, |2.3|, |-6.33|, |4.75|, |0|
|-6.33|, |4.75|, |-3.2|, |2.3|, |0|
On a map, a space museum is located at (15, -2). A theater is located at (15, 18). If each unit on the map is a city block, how many city blocks is the space museum from the theater? Explain how you know.
20 city blocks
What is a coordinate plane? How many quadrants are on a coordinate plane?
A coordinate plane is a grid containing two numbers lines that intersect at 0. A coordinate plane has 4 quadrants.
The weather channel showed the daily low temperatures for several days in Kansas. Write the temperatures in order from least to greatest. On which day was the coldest?
Monday: 11
Tuesday: -3
Wednesday: 7
Thursday: -5
Friday: 4
-5, -3, 4, 7, 11
Thursday was the coldest.
The coordinate plane shows the location of Miss Wiehl's house located on (-8.25, 1).
Draw a coordinate plane and label Miss Wiehl's house.
Look on the board for the correct answer.
In California, there is a ship that is located at the depth of |-180| feet. There's treasure that is believed to be at a depth of |-184| feet. Which is farther below ground, the ship or the treasure? Explain your reasoning.
The treasure is further below ground.
On a map, James is standing at (200, 21) and Kyler is standing at (150, 21). If James walks 25 to the left and Kyler walks 25 to the left, will they be standing together? Explain.
No, because James would be standing at (175, 21) and Kyler would be standing at (125, 21). Kyler needs to walk 25 to the right to be with James at (175, 21)
What is an ordered pair? What is another name for ordered pair?
An Ordered Pair is a set of numbers that gives a location of a point relative to each axis.
Another name for ordered pair is coordinate.
