We practice rounding 4-digit numbers to various places (to the nearest ten, nearest hundred, and nearest thousand). I explain a systematic method for rounding: draw a cutoff line right after the digit you're rounding to. Then look at the digit AFTER that line... if that digit is 0-4, round down. If that digit is 5-9, round up. This lesson is meant for 4th grade math. Check out also my other videos for 4th grade at
