Lesson Worksheet: Estimating Quotients: One-Digit Divisors Mathematics • 4th Grade

In this worksheet, we will practice replacing factors with compatible numbers to estimate the quotient when the divisor is a one-digit number.


Estimate the quotient of the following operation: 620÷7.


Use compatible numbers to estimate the result of the following division.


Benjamin has 179 stamps. He wants to put them in his album. He puts 2 stamps on each page. Estimate the number of full pages he will have in his album to the nearest ten.


A school that has 234 students is arranging a competition. The students are split into teams. Each team has 6 students. Estimate how many teams there are to the nearest 10.

Natalie wants to estimate the quotient of 35÷8. She thinks of two ways to do this. The first one is 32÷8=4 and the second one is 40÷8=5.

Natalie chose the second division as 32 is closer to 35 than 40 and estimated the quotient to be 4.

Follow Natalie’s method to estimate the quotient of 23÷5.
