Estimating Quotient
Examples, solutions, videos, stories, and songs to teach Grade 3 students how to estimate quotients using compatible numbers and rounding.
The following diagram shows an example of estimating quotient using compatible numbers. Scroll down the page for more examples and solutions.
Estimate Quotients using Compatible Numbers
We can use compatible numbers to estimate quotients.
Compatible numbers are numbers that are easy to compute mentally.
A zebra’s heart beats 138 times in 3 minutes. About how many times does it beat in 1 minute?
Example 1: Estimate 138 ÷ 4
Example 2: Use compatible numbers to find two estimates that the quotient is between 1,327 ÷ 5
Using Rounding to Estimate Quotients
- 2,357 ÷ 37
- 1,567 ÷ 352
Estimate Quotients
Example:
Circuses have been around for more than 200 years. They sometimes travel by train. Suppose a circus travels 642 miles in 8 hours. About how many miles per hour did the train travel?
