Lesson to be used by EDI-trained teachers only. 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 A number line shows the order of numbers based on their value. 50

Lesson to be used by EDI-trained teachers only. Concept Development A positive integer is a number greater than zero. Positive integers are shown with a positive sign (+) or no symbol. +3 or 3, +21 or 21 Zero is neither negative nor positive. A negative integer is a number less than zero. Negative integers are shown with a negative sign (-). –3, – In your own words, what is different between negative and positive integers? Negative and positive integers are different because __________________. CFU What type of integer is -4 ? How do you know? A Positive B Negative What type of integer is 9 ? How do you know?
