Understanding Number Lines

The video tutorial explains how to locate numbers on a number line using different increments. It starts by finding 30 using increments of 3, demonstrating the counting process and alternative methods. Next, it locates 24 with the same increment. Finally, it shows how to find 20 using increments of 4, emphasizing the counting process and alternative thinking strategies.
