Math Lesson: You will be able to write and calculate unit rates by using proportional relationships Life lesson: Be Present- Minded Be Committed to Excellence Be a Positive Force Take Action! Write in Planner: HW: Page 59 Computation B due by Friday Classwork: Unit Rates

Ratio/Rate: A ratio that compares two quantities measured in different units. Example: 233 words in 2 minutes 233 words 2 minutes Unit Rate:/Proportion: A rate that has a denominator of one. Example: 233 words in 2 minutes = words per minute ? 1 minute 233 words 2 minutes =

Practice: Process: Set up the Rate/Proportion Solve An airplane flew 325 miles in 25 minutes. How fast was it flying in miles per minute? 325 mi 25 minutes ? 1 minute = 13 miles per minute 780 miles per hour ? 1 Hour Per hour?

Important! In this unit you are allowed calculators! SO! SETTING up the PROBLEM IS EXTREMELY IMPORTANT!

Write the unit rate: 720 miles 1.5 hours Fly 720 miles in 1.5 hours. 480 miles per hour = ? 1 hour How fast was it flying in miles per hour? Practice #1

Write the unit rate: 1600 miles 20 hours Drive 1,600 miles in 20 hours 80 miles per hour = ? 1 hour How many miles can we drive in one hour? Practice #2

Write the unit rate: 55 cups 11 cakes fifty five cups of flour for 11 cakes 5 cups of flour per cake = ? 1 cake How many cups of flour for 1 cake? Practice #3

Write the unit rate: $ tickets $25.50 for 15 tickets $1.70 per ticket = ? 1 ticket How much for 1 ticket? Practice #4

Team Task Find the Best Deal You will be able to distinguish the similarities and differences between Fractions and Ratios. AND compute Unit Rates.

Communication Prompt Why would you want to know the miles per gallon your car uses when it is driven? Do you think the unit rate changes if you are driving on a freeway or driving on streets? Why or why not? (Copy and reply in journals)

Homework Page 59 Computation B due Friday You will be able to solve multi-step equations by applying distributive property and combining like terms.
