Identifying Integers and Their Opposites on Number Lines

This video tutorial by Mrs. K covers the concept of integers and their opposites using a horizontal number line. It begins with defining integers as whole positive numbers and their opposites, followed by a detailed explanation of how to represent these on a number line. The tutorial emphasizes the importance of zero as a neutral point and demonstrates how to identify opposites by their equal distance from zero on opposite sides. The lesson concludes with examples and a light-hearted note about the teacher's puppy.
