The video tutorial introduces the concept of estimation, explaining it as making a smart guess based on what you know. It provides examples such as estimating marbles in a jar, large quantities like stars, and comparing items in jars. The tutorial emphasizes that estimation is useful when exact counting is impractical, and it guides viewers through various examples to practice estimating different objects.
