Understanding when it is appropriate to estimate, whether our estimates are reasonable, and how to become better estimators are extremely important skills for everyone.

Check out these infographics: As you look at them, think about whether each needs precision or estimation?

These are questions we usually estimate the answers to:

How far is it to my friend's house?
How long until we eat?
How much money is there in my bank?
How big is that tree?
When will the game be over?
About how many people are in this room?
How long will we have to stand in line?
When will we get there?
How much bigger is it?
Do I have enough money to buy that?
How long will it take?
