We will discuss the different methods of estimation, including rounding numbers, using mental math, and estimating with fractions.

What is Estimation in Mathematics?

Estimation in mathematics is the process of approximating a value or quantity. It involves making a rough calculation or prediction based on available information. Estimation is an essential skill in mathematics, as it helps us to make sense of large or complex numbers. It's also a critical skill in real-life situations, such as calculating the cost of groceries or estimating the time it takes to complete a task.

Methods of Estimation

There are several methods of estimation, including:

Rounding Numbers: Rounding numbers involves approximating a value by rounding it to the nearest ten, hundred, or thousand. For example, the number 936 can be rounded to 900 or 1000.
Mental Math: Mental math involves using mental calculations to estimate a value. For example, you can estimate the value of 936 by breaking it down into smaller parts, such as 900 + 30 + 6.
Estimating with Fractions: Estimating with fractions involves using fractions to approximate a value. For example, the number 936 can be estimated as 900 + 1/3 of 36.

Estimating 936 using Rounding Numbers

To estimate 936 using rounding numbers, we can round it to the nearest ten, hundred, or thousand. Let's start by rounding it to the nearest ten.
