Estimating multi-digit division (Full video)

Khan Academy

Supporting grades: 5

Description: Estimate to find reasonable solutions to multi-digit division problems. What we wanna do in this video is get some practice estimating multi-digit division problems. I would say this is going to be roughly the same thing as 800, is gonna be roughly equal to 800 divided by 20. For example, I would then say, if I was just doing this purely in my head, I would say, well, 100 divided by 20 is five, so 800 divided by 20 is equal to 40.
