Divide Using Partial Quotients and Rectangular Models

Front

What is division?

Back

Division is the process of splitting a number into equal parts. It answers the question of how many times one number is contained within another.

Front

What is a quotient?

Back

The quotient is the result of a division problem. It tells how many times the divisor fits into the dividend.

Front

What is a dividend?

Back

The dividend is the number that is being divided in a division problem.

Front

What is a divisor?

Back

The divisor is the number by which the dividend is divided.

Front

What is a partial quotient?

Back

A partial quotient is a method of division where you subtract multiples of the divisor from the dividend to find the quotient.

How do you use partial quotients to divide 184 by 8?

Back

1. Start with 184. 2. Subtract 80 (10 times 8) to get 104. 3. Subtract 80 again to get 24. 4. Subtract 16 (2 times 8) to get 8. 5. Subtract 8 (1 time 8) to get 0. 6. Add the partial quotients: 10 + 10 + 2 + 1 = 23.

Front

What is a rectangular model in division?

Back

A rectangular model visually represents division by showing how many equal groups can be made from the dividend.

Front

How do you use a rectangular model to divide 246 by 3?

Back

1. Draw a rectangle and label it with 246. 2. Divide the rectangle into 3 equal parts. 3. Each part represents the quotient. 4. The answer is 82.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you know that 3 x 4 = 12, then you can also say that 12 ÷ 4 = 3.

Front

What does it mean to find the total of partial quotients?

Back

Finding the total of partial quotients means adding all the partial quotients together to get the final quotient.
