Learning Objective Name _______________________ Today, we will identify 1 negative and positive integers on a number line. 1 find CFU What are we going to do today? What does identify mean? Identify means ________. CFU Students, you already know that positive numbers can be represented on a number line based on their value. Negative numbers can also be represented on a number line. Today we will identify negative and positive numbers, called integers, on a number line. Complete the number line below by filling in the blanks. Activate (or provide) Prior Knowledge 12346789 A number line shows the order of numbers based on their value. 50
