Lesson: Estimating Quotients: Two-Digit Divisors Mathematics • 5th Grade

In this lesson, we will learn how to replace factors with compatible numbers to estimate the quotient when the divisor is a two-digit number.

Lesson Plan

Students will be able to

use basic multiplication and division facts to find the two values that the quotient is between,
use basic facts to estimate the quotient,
discuss the accuracy of estimates,
use estimation to state whether an answer is reasonable.

Q1:

Find the quotient of without using a calculator. Use the result to find the quotient of without performing division.

Q2:

Is , or ? Solve without performing the division.

Q3:

A company sells 349 items for $49. Estimate the price of one item to the nearest dollar.
