What Is an Estimate?

As students work to strengthen their computation skills, estimation is another topic they will learn about. This can be a tricky concept for young learners because they’ve been working so hard on getting the exact answer for quite some time! With estimation, we are teaching them to answer a problem with a number that is ‘pretty close’ to the right answer.

So, how can we explain what an estimate is to our students? Read on for a simple definition to use with your students!

An estimate is like making a good guess. You can guess the amount of something or the answer to a problem using rounding or compatible numbers.

Imagine you’re trying to figure out how many jellybeans are in a big jar, but you can’t count them one by one. So, you look at the jar and take a guess. It’s not the exact number but a close guess based on what you can see and know. Estimating helps us make quick guesses when we can’t find the exact answer easily.
