Learning Objective: Students Will Be Able To… interpret the rationality of quotients and apply this skill to “real-world” problems.
Language Objective: SWBAT define and identify Dividend, Divisor, and Quotient as they relate to division of fractional quantities.

Lesson Vocabulary and Language Objectives

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)

An Italian sausage is 8 inches long. How many pieces of sausage can be cut from the 8-inch piece of sausage if each piece is to be
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.
