Teacher’s Guide to Using theChapter 12 Resource MastersThe Fast File Chapter Resource system allows you to conveniently file the resourcesyou use most often. The Chapter 12 Resource Masters includes the core materialsneeded for Chapter 12. These materials include worksheets, extensions, andassessment options. The answers for these pages appear at the back of this booklet.All of the materials found in this booklet are included for viewing and printing in theAlgebra 2 TeacherWorks CD-ROM.Vocabulary BuilderPracticePages vii–viiiinclude a student study tool that presentsup to twenty of the key vocabulary termsfrom the chapter. Students are to recorddefinitions and/or examples for each term.You may suggest that students highlight orstar the terms with which they are notfamiliar.There is one master for eachlesson. These problems more closely followthe structure of the Practice and Applysection of the Student Edition exercises.These exercises are of average difficulty.WHEN TO USE These provide additionalpractice options or may be used ashomework for second day teaching of thelesson.WHEN TO USE Give these pages tostudents before beginning Lesson 12-1.Encourage them to add these pages to theirAlgebra 2 Study Notebook. Remind themto add definitions and examples as theycomplete each lesson.Reading to Learn MathematicsOne master is included for each lesson. Thefirst section of each master asks questionsabout the opening paragraph of the lessonin the Student Edition. Additionalquestions ask students to interpret thecontext of and relationships among termsin the lesson. Finally, students are asked tosummarize what they have learned usingvarious representation techniques.Study Guide and InterventionEach lesson in Algebra 2 addresses twoobjectives. There is one Study Guide andIntervention master for each objective.WHEN TO USE Use these masters asWHEN TO USE This master can be usedreteaching activities for students who needadditional reinforcement. These pages canalso be used in conjunction with the StudentEdition as an instructional tool for studentswho have been absent.as a study tool when presenting the lessonor as an informal reading assessment afterpresenting the lesson. It is also a helpfultool for ELL (English Language Learner)students.Skills PracticeThere is one master foreach lesson. These provide computationalpractice at a basic level.EnrichmentThere is one extensionmaster for each lesson. These activities mayextend the concepts in the lesson, offer anhistorical or multicultural look at theconcepts, or widen students’ perspectives onthe mathematics they are learning. Theseare not written exclusively for honorsstudents, but are accessible for use with alllevels of students.WHEN TO USE These masters can beused with students who have weakermathematics backgrounds or needadditional reinforcement.WHEN TO USE These may be used asextra credit, short-term projects, or asactivities for days when class periods areshortened.

Assessment OptionsIntermediate AssessmentThe assessment masters in the Chapter 12Resource Masters offer a wide range ofassessment tools for intermediate and finalassessment. The following lists describe eachassessment master and its intended use. Four free-response quizzes are includedto offer assessment at appropriateintervals in the chapter. A Mid-Chapter Test provides an optionto assess the first half of the chapter. It iscomposed of both multiple-choice andfree-response questions.Chapter AssessmentCHAPTER TESTSContinuing Assessment Form 1 contains multiple-choice questionsand is intended for use with basic levelstudents. The Cumulative Review providesstudents an opportunity to reinforce andretain skills as they proceed throughtheir study of Algebra 2. It can also beused as a test. This master includesfree-response questions. Forms 2A and 2B contain multiple-choicequestions aimed at the average levelstudent. These tests are similar in formatto offer comparable testing situations. The Standardized Test Practice offerscontinuing review of algebra concepts invarious formats, which may appear onthe standardized tests that they mayencounter. This practice includes multiplechoice, grid-in, and quantitativecomparison questions. Bubble-in andgrid-in answer sections are provided onthe master. Forms 2C and 2D are composed of freeresponse questions aimed at the averagelevel student. These tests are similar informat to offer comparable testingsituations. Grids with axes are providedfor questions assessing graphing skills. Form 3 is an advanced level test withfree-response questions. Grids withoutaxes are provided for questions assessinggraphing skills.AnswersAll of the above tests include a freeresponse Bonus question. Page A1 is an answer sheet for theStandardized Test Practice questionsthat appear in the Student Edition onpages 694–695. This improves students’familiarity with the answer formats theymay encounter in test taking. The Open-Ended Assessment includesperformance assessment tasks that aresuitable for all students. A scoring rubricis included for evaluation guidelines.Sample answers are provided forassessment. The answers for the lesson-by-lessonmasters are provided as reduced pageswith answers appearing in red. A Vocabulary Test, suitable for allstudents, includes a list of the vocabularywords in the chapter and ten questionsassessing students’ knowledge of thoseterms.

NAME DATEPERIOD12-1 Study Guide and InterventionThe Counting PrincipleIndependent EventsIf the outcome of one event does not affect the outcome ofanother event and vice versa, the events are called independent events.FundamentalCounting PrincipleIf event M can occur in m ways and is followed by event N that can occur in n ways,then the event M followed by the event N can occur in m n ways.FOOD For the Breakfast Special at the Country Pantry, customerscan choose their eggs scrambled, fried, or poached, whole wheat or white toast,and either orange, apple, tomato, or grapefruit juice. How many differentBreakfast Specials can a customer order?A customer’s choice of eggs does not affect his or her choice of toast or juice, so the eventsare independent. There are 3 ways to choose eggs, 2 ways to choose toast, and 4 ways tochoose juice. By the Fundamental Counting Principle, there are 3 2 4 or 24 ways tochoose the Breakfast Special.ExercisesSolve each problem.1.

NAME DATEPERIOD12-1 Study Guide and Intervention(continued)The Counting PrincipleDependent EventsIf the outcome of an event does affect the outcome of another event,the two events are said to be dependent. The Fundamental Counting Principle still applies.ExampleENTERTAINMENT The guests at a sleepover brought 8 videos. Theydecided they would only watch 3 videos. How many orders of 3 different videosare possible?After the group chooses to watch a video, they will not choose to watch it again, so thechoices of videos are dependent events.There are 8 choices for the first video. That leaves 7 choices for the second. After they choosethe first 2 videos, there are 6 remaining choices. Thus by the Fundamental CountingPrinciple, there are 8 7 6 or 336 orders of 3 different videos.ExercisesSolve each problem.1. Three students are scheduled to give oral reports on Monday.

How many choices are there for each letter? for each digit?Reading the Lesson1. Shamim is signing up for her classes. Most of her classes are required, but she has twoelectives. For her arts class, she can chose between Art, Band, Chorus, or Drama. For herlanguage class, she can choose between French, German, and Spanish.a. To organize her choices, Shamim decides to make a tree diagram. Let A, B, C, and Drepresent Art, Band, Chorus, and Drama, and F, G, and S represent French, German,and Spanish. Complete the following diagram.b. How could Shamim have found the number of possible combinations without making atree diagram? Sample answer: Multiply the number of choices for herarts class by the number of choices for her language class: 3 4 12.2. A jar contains 6 red marbles, 4 blue marbles, and 3 yellow marbles. Indicate whether theevents described are dependent or independent.a. A marble is drawn out of the jar and is not replaced. A second marble is drawn.dependentb. A marble is drawn out of the jar and is put back in. The jar is shaken. A secondmarble is drawn. independentHelping You Remember3. One definition of independent is “not determined or influenced by someone or somethingelse.” How can this definition help you remember the difference between independentand dependent events? Sample answer: If the outcome of one event does notaffect or influence the outcome of another, the events are independent. Ifthe outcome of one event does affect or influence the outcome ofanother, the events are dependent. Glencoe/McGraw-Hill703Glencoe Algebra 2Lesson 12-126; 10
