The video tutorial teaches how to solve time-related problems using a number line. It begins with an introduction to the concept and explains how a number line can represent time intervals. The tutorial includes examples, such as calculating time spent playing games and solving word problems like the time taken to eat a lollipop. The video concludes with another example of calculating time spent at a friend's house. Throughout, the number line is used to visually represent and solve time problems.
