Lesson Topic: Finding a Rate by Dividing Two Quantities Lesson Objective: I can… • Convert measurement units using rates to correctly solve a word problem. Essential Question • How is it relevant?

Behavior & Academic Expectations • Classroom rules • Participation in partner/group work • Hand signal • Raise your hand & wait to get called on before speaking out • Stay focused • We are still doing row points

Agenda and Goal I can: Convert measurement units using rates to correctly solve a word problem. Exit Ticket: A word problem with an optional extra challenge to create andsolve your own word problem that involves converting measurement units using rates.

Vocabulary Convert - What does it mean?

Let’s Review • How can we turn a whole number into a fraction? • Why does this work? • We have multiplied fractions like this before • Example: 2/3 x 4 *Take Notes – showing all work*

Example 1 At Fun Burger, the Burger Master can make hamburgers at a rate of 4 burgers/minute. In order to address the heavy volume of customers, he needs to continue at this rate for 30 minutes. If he continues to make hamburgers at this pace, how many hamburgers will the Burger Master make in 30 minutes? Why? *Take Notes – showing all work*

Steps for this Process • What’s the rate? • Multiply it by the quantity – Think what you are trying to end up with. • What units can we cancel out? • What’s our solution? *Take Notes*

Example 2 – Let’s Do One Together Chandra is an editor at the New York Gazette. Her job is to read over each article before it is printed in the newspaper. If Chandra can read 10 words/second, how many words can she read in 60 seconds? Why? *Take Notes & Show your work* • Compare to how we solved 1stexercise

Example 3 – Do With a Partner (or Group of 3 in your Row) • Helena works for a publishing firm. She is considered an average typist and can type 52 words/minute. If she continues at this rate, how many minutes would it take Helen to type 104 words? Question your partner: Why? *Show your work* If you finish early… make a ratio table, tape diagram, and/or double number line for the problem (only after you have found the answer). • Compare to how we solved first 2 exercises

Example 4 – Do On Your Own*Voice Level 0* 3. To train for an upcoming marathon, Alvin runs 9 miles a day. If Alvin runs 9 miles every day for 30 days, how many total miles will he run? Why? *Show your work* If you finish early… make a ratio table, tape diagram, and/or double number line for the problem (only after you have found the answer). • Compare to how we solved first few exercises

Lesson Summary… • We can convert measurement units using rates. The information can be used to further interpret the problem. Here is an example: (5 )(10 min) = ()(10 min) = 50 gal.

Rate Your Learning… (In your notes) (Think about our “I can” statement as you’re rating) 1 – I do not understand this lesson. 2 – I can do this lesson with help. 3 – I understand this lesson 4 – I could teach this lesson. How will you continue to expand your knowledge?

A Look Ahead… • Your homework worksheet is due tomorrow • Come into tutoring tomorrow if you do not feel you can confidently achieve our “I can” statement from today • Tomorrow we will learn about Comparison Shopping - Unit Price and Related Measurement Conversions

Exit Ticket Alejandra drove from Michigan to Colorado to visit her friend. The speed limit on the highway was 70 miles/hour. If Alejandra’s combined driving time for the trip was 14 hours, how many miles did Alejandra drive? Show your work. Extra Challenge (Optional): Create & solve your own word problem that involves converting measurement units using rates. After you turn it in, work on homework worksheet
