# Lesson 13 Divide Using Partial Quotients

Let’s use an algorithm using partial quotients to divide three-digit and four-digit dividends by two-digit divisors.

## Warm-up Number Talk: Divide

Find the value of each expression mentally.

## Activity 1 Compare Solutions

## Problem 1

Use an algorithm using partial quotients to find the value of one of the quotients. Be prepared to explain how you found the quotient.

Partner 1:

Partner 2:

## Problem 2

Explain to your partner how you found the value of the quotient.

Pair up with another group and compare your work.

## Activity 2 Estimate and Solve

Estimate the value of each quotient. Then, use an algorithm using partial quotients to find the value.

A reasonable estimate for

is: A reasonable estimate for

is: A reasonable estimate for

is:
