Rounding Numbers to the Nearest Ten

The video tutorial reviews rounding numbers to the nearest ten, focusing on identifying strong and weak numbers. Strong numbers (5-9) push the tens digit up, while weak numbers (0-4) do not. The tutorial provides examples of rounding both two-digit and three-digit numbers, emphasizing the importance of the ones place in determining whether to round up or stay the same. Practice problems are given for students to apply the concepts learned.
