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
