Description

Find whole-number quotients and remainders with up to four-digit dividends/one-digit divisors using strategies based on place value, the properties of operations, and the relationship between multiplication/division. Explain the calculations by using equations, rectangular arrays, and area models.

Vocabulary Words

divisor

quotient

partition

place value

area model

compatible numbers

remainder

Instructions

Play through this interactive game to learn about Divide Using Four Digit Dividends. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Understand that algorithms for multiplication and division are abbreviations for reasoning about quantities.

Divide 2-, 3-, and 4-digit numbers by 1-digit numbers with remainders.

745 ÷ 3 = ? interpreted as Divide 7 hundreds, 4 tens, 5 ones equally among 3 groups, starting with hundreds using the reasoning of the distributive property.

See quotients as multiples of 10, 100, or 1000 and one-digit numbers. For example, 42 / 6 is related to 420 / 6 and 4200 / 6.

Use area models to model division with four digit dividends and one digit divisors, with whole number quotients and remainders.

In multi-digit division find the greatest multiple less than a given number (When dividing by 8, the greatest multiple of 8 less than 50 is 8 x 6 = 48.

Divide 2-, 3-, and 4-digit numbers by 1-digit numbers without remainders.

Discussion Questions

Before the Game

How can you use compatible numbers to estimate quotients? What is the relationship between multiplication and division? If you have 3 friends and 12 cookies, how can you share your cookies amongst you all? If you know that the area of a rectangle is 24 and one side length is 6, how can you find the missing side length? Would it help you to better understand division if you could see the dividend broken down into 100s, 10s and 1s? What do you know about area models for division?

After the Game

Can you think of a real-world example of when you would use area division model to solve a problem? Do all division problems have a remainder of zero? How does changing the value of your divisor affect the quotient? Which division strategy (partial quotients, rectangular array, area model) do you think is best? In this game use used area models with base 10 to solve division problems, do you always have to use multiples of 10? Can you explain how being proficient in finding the highest multiple that fits into your dividend useful in finding the answer to more difficult division problems?
