Comparing Integers and Temperature

This video tutorial introduces 7th-grade students to the concept of comparing integers. It explains the idea of comparison using real-life examples, such as temperature differences between two cities. The tutorial further illustrates how to use a number line to determine which integer is greater or smaller. Finally, it guides students on how to order integers in ascending order, emphasizing the importance of understanding the position of numbers on a number line.
