Exploring Positive and Negative Numbers

The video tutorial by Miss Ewing introduces positive and negative numbers using number lines. It explains how to identify higher and lower numbers by moving right or left on a horizontal number line and up or down on a vertical number line. The concept of symmetry is discussed, highlighting how numbers have opposites, except zero, which is unique. Practical examples are provided to find opposites and understand their positions. Real-world applications, such as banking and temperature, are used to illustrate positive and negative numbers. The tutorial concludes with a summary and an exit slip to reinforce learning.
