Rounding to nearest 100 (Full video)

Khan Academy

Supporting grades: 3

Description: Learn to use a number line to round 3-digit numbers to the nearest hundred. Created by Sal Khan. We want to look at the tens place to decide which multiple of 100 it is closer to. And the rules are very similar to when we're rounding to the nearest tens place or really any place. We look one place to the right of it.
