Graphing Integers on a Number Line

In this video, Mrs. Brown introduces graphing integers on a number line. She explains the importance of setting up the number line correctly, ensuring positive numbers count up from zero and negative numbers count down. The video demonstrates graphing individual integers like -2 and 5, and discusses graphing multiple integers on the same line. Mrs. Brown also covers using different intervals, such as counting by twos, to accommodate a range of numbers. The video concludes with a summary of the key points discussed.

What is the primary tool used for graphing integers?

• A scatter plot

• A pie chart

• A bar graph

• A number line

When graphing integers, which direction do positive numbers move away from zero?

• Down

• Right

• Left

• Up

How do you graph the integer -2 on a number line?

• Put a dot at -1

• Put a dot at 0

• Put a dot at 2

• Put a dot at -2

What is important to ensure when setting up a number line?

• Positive numbers count down towards zero

• Negative numbers count up away from zero

• Negative numbers count down towards zero

• Positive numbers count up away from zero

What does a set of numbers represent in graphing?

• A pair of numbers to be graphed

• A range of numbers to be graphed

• A single number to be graphed

• A list of numbers to be graphed

If you don't have enough space on a number line, what can you do?

• Count by threes

• Skip numbers

• Count by ones only

• Count by twos or other intervals

What is crucial about each interval on a number line?

• Intervals must be skipped

• Each interval must be different

• Each interval must be the same amount

• Intervals can be random

Where would -3 be located if you are counting by twos?

• Halfway between -2 and 0

• Halfway between -4 and -2

• At -2

• At -4

What can you do if you want to start your number line at a different point?

• Start at the highest number

• Start at zero and count by ones

• Always start at zero

• Start at any point and count by any interval

What is the main goal when graphing multiple integers on the same number line?

• Graph them all with a line

• Graph only the positive integers

• Graph only the negative integers

• Graph them all with a dot at the correct points
