Friday math movie: A clever way to estimate enormous numbers
[06 Sep 2013]
It’s important to be able to make estimates before attempting problems. Very few students get practice at this important math skill.
In this video, Michael Mitchell begins with an overview of scientific notation and goes on to give us some suggestions on using powers of 10 to estimate large numbers.
See the associated TED-Ed lesson that goes with this video.
The video is one of the highly recommended 8 Math Talks to Blow Your Mind by TED.
