4 Lesson ObjectiveObjective: Students will compare ratios using unit rates, tables and graphs. Language Objective: Students will review and apply vocabulary like ratio, ratio table, rates, and unit rates. Lesson DescriptionThis lesson asks students to compare ratios using tables and also graphs. This lesson assumes that students have reviewed how to graph points from a table but will provide a brief review prior to tackling comparing ratios with tables. We will focus on using unit rates to help students compare different real-world examples. The next lesson in this unit will focus on more complicated examples of using tables to compare real-world examples. Lesson Overview (1 of 3)

5 Lesson Vocabulary Ratio Table – a table that include two quantities being compared Ratio – a comparison of two different values Unit Rate – a comparison of two different values where the second value is 1 unit Materials -Class set of notes -Rulers for Graphing Scaffolding We will use frequent partner talk and pair-shares to review ratio tables. We will then use practice from the Warm-Up to help students practice using tables to find a unit rate. The class notes can be provided to students with or without answers as an accommodation. Enrichment For graphing examples, students with strong skills may want to graph both ratios on one coordinate plane, almost like a system of equations. - Teachers can provide alternative examples for students to practice this higher skill, examples can be found on websites.

6 Lesson Overview (3 of 3) Common Core State Standard 6.RP.3. Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. Make tables of equivalent ratios relating quantities with whole- number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios. Before and AfterBefore this lesson, students have used tables to find ratios of real- world examples. This lesson will extend student learning by asking students to compare different ratios using a ratio table and graphing. Students will also learn which tools (graphs or tables) are best for them to compare real-world ratios. Topic BackgroundToday’s lesson relates to the real-world in many ways; we will use money and speed as two major real-world examples. Further, we will focus on how to use tables to extrapolate data when given tables.

Back to Lesson 26 1 st Time Users of 21 st Century Lessons Welcome to 21 st Century Lessons! We are a non-profit organization that is funded through an AFT (American Federation of Teachers) Innovation Grant. Our mission is to increase student achievement by providing teachers with free world-class lessons that can be taught via an LCD projector and a computer. 21 st Century Lessons are extremely comprehensive; we include everything from warm–ups and assessments, to scaffolding for English language learners and special education students. The lessons are designed into coherent units that are completely aligned with the Common Core State Standards, and utilize research-based best practices to help you improve your students’ math abilities. Additionally, all of our lessons are completely modifiable so you can adapt them if you like. Description of 21 st Century Lessons: Next Slide

27 1 st Time Users of 21 st Century Lessons The lesson that you are currently looking at is part of a unit that teaches the following Common Core Standards: Standards for This Unit Next SlideBack to Lesson

28 1 st Time Users of 21 st Century Lessons In order to properly use 21 st Century Lessons you will need to possess or arrange the following things: Required: PowerPoint for P.C. (any version should work) Note: Certain capabilities in the PowerPoint Lessons are not compatible with PowerPoint for Mac, leading to some loss of functionality for Mac PowerPoint users. An LCD projector Pre-arranged student groups of 2 – (Many lessons utilize student pairings. Pairs should be seated close by and be ready to work together at a moment’s notice. Scissors – at least 1 for every pair Requirements to teach 21 st Century Lessons: Next SlideBack to Lesson

29 1 st Time Users of 21 st Century Lessons Computer speakers that can amplify sound throughout the entire class “Calling Sticks” – a class set of popsicle sticks with a student’s name on each one A remote control or wireless presenter tool– to be able to advance the PowerPoint slides from anywhere in your classroom Personalize PowerPoints by substituting any names and pictures of children we included in the PowerPoint with names and pictures of your own students. Since many lessons utilize short, partner-processing activities, you will want a pre- established technique for efficiently getting your students’ attention. (“hands- up”, Count from “5” to “0” etc.) Project onto a whiteboard so you or your students can solve problems by hand. (Lessons often have a digital option for showing how to solve a problem, but you may feel it is more effective to show the work by hand on a whiteboard.) Internet connectivity – without the internet you may not have full functionality for some lessons. Strongly Suggested to teach 21 st Century Lessons: Next SlideBack to Lesson

30 1 st Time Users of 21 st Century Lessons We suggest spending minutes reviewing a lesson before teaching it. In order to review the lesson run the PowerPoint in “Slideshow “- Presenters View and advance to the “Lesson Overview” slide. By clicking on the various tabs this slide will provide you with a lot of valuable information. It is not necessary to read through each tab in order to teach the lesson, but we encourage you to figure out which tabs are most useful for you. Note: All of our lessons are designed to be taught during a minute class. If your class is shorter than this you will have to decide which sections to condense/remove. If your class is longer we suggest incorporating some of the “challenge” questions if available. Lesson Preparation (Slide 1 of 2) Next Slide Back to Lesson

31 1 st Time Users of 21 st Century Lessons After reviewing the overview slide, click your way through the PowerPoint. As you go, make sure to read the presenter note section beneath each slide. The note section is divided into two sections: “In-Class Notes” and “Preparation Notes.” The In-Class Notes are designed to be concise, bulleted information that you can use “on the fly” as you teach the lesson. Included in In-Class Notes are: a) a suggested time frame for the lesson, so you can determine whether you want to speed up, slow down, or skip an activity, b) key questions and points that you may want to bring up with your students to get at the heart of the content, and c) answers to any questions being presented on the slide. The Preparation Notes use a narrative form to explain how we envision the activity shown on the slide to be delivered as well as the rationale for the activity and any insight that we may have.
