Why do we round to help us estimate an answer?

Estimating an answer can help us understand if our exact answer is close or reasonable, when checking our work. 

We estimate and round numbers when we want to do quick math in our heads. We might use this when shopping to see if we have enough money.

*Students might have other answers or examples.
