Division Concepts and Estimation Techniques

This video tutorial covers the basics of dividing whole numbers, focusing on key vocabulary such as dividend, divisor, and quotient. It introduces the concept of estimating quotients through a practical word problem involving zoo visitors. The lesson provides a step-by-step guide to solving the problem using estimation and checks the accuracy of the solution with long division. The tutorial concludes with tips on handling remainders and verifying work.

What is the term used for the result of a division problem?

• Quotient

• Product

• Divisor

• Dividend

In the zoo word problem, what is the first step in estimating the quotient?

• Divide the total visitors by the number of holidays

• Round the total visitors to the nearest 10,000

• Subtract the holidays from the total days

• Multiply the total visitors by the number of days open

How many days is the zoo open in a year according to the problem?

• 365

• 364

• 362

• 360

What is the rounded divisor used in the estimation process?

• 300

• 350

• 400

• 450

What is the estimated quotient when dividing 100,000 by 400?

• 200

• 350

• 250

• 300

What is the purpose of the accuracy check in the division process?

• To round the dividend

• To verify the estimated quotient

• To calculate the remainder

• To find the exact quotient

What operation is used to verify the accuracy of the division?

• Addition

• Subtraction

• Multiplication

• Division

What is the final quotient obtained after performing long division?

• 280

• 250

• 260

• 270

How do you know if your estimated quotient is close to the actual quotient?

• If the estimated quotient is close to the actual quotient

• If the estimated quotient is less than the actual quotient

• If the estimated quotient is within 10% of the actual quotient

• If the estimated quotient is exactly the same as the actual quotient

What should you do if there is a remainder in the division process?

• Add it to the quotient

• Ignore it

• Note it as a remainder

• Write it as a fraction
