Word Definition Example/Symbol

Dividend A number to be divided

Divisor The number a dividend is divided by

Quotient The number that results from division, solution of division = 5

Launch 1 – Division: Larger Dividend

Agenda

Once Twice

Concept 1When the dividend is larger than the divisor,

the quotient is always greater than 1.

Dividend Divisor Quotient

*On the lines below, write what you think Concept 1 means in your own words. If needed, you can use the number example, 4 ÷ 2, to help in your explanation. Please use either the words "fits into" or "holds" in your explanation. Once finished, share your explanation with a table partner. (Everyone must share)

Summary & Key to Leave

Name

1) Explain whether the quotient to the problem below is greater than or less than 1. Use the words “Dividend” and “Divisor” in your explanation.

3) A hotdog is 7 ½ inches long. How many pieces can be cut from the hotdog if each piece is to be two-thirds of an inch?

2) How many halves, (1/2), are there in an eighth, (1/8)?

Problems 2 & 3 involve division to solve: Place a box around the dividend and circle the divisor. Write a numerical expression or equation. Then write whether the quotients will be greater than or less than 1.
