1 GHS Curse Syllabus General Curse Infrmatin Curse Title: Accelerated Algebra 2 Year: Department: Math Rm #: 112 Perids Taught: 3, 4, 6, 7 Resurces: Online editin f Algebra 2: Kanld, Burger, Dixn, Larsn, Leinwand; Hughtn Mifflin Harcrt ISBN Available at my.hrw.cm Curse Descriptin: Building n their wrk with linear, quadratic, and expnential functins, students extend their repertire f functins t include plynmial, ratinal, and radical functins. Students wrk clsely with the expressins that define the functins, and cntinue t expand and hne their abilities t mdel situatins and t slve equatins, including slving quadratic equatins ver the set f cmplex numbers and slving expnential equatins using the prperties f lgarithms. The 4 critical areas f fcus are: Plynmial, ratinal and radical relatinships, Trignmetry functins, mdeling with functins, and inferences and cnclusins frm data. The Mathematical Practice Standards apply thrughut the curse and, tgether with the cntent standards, prescribe that students experience mathematics as a cherent, useful, and lgical subject that makes use f their ability t make sense f prblem situatins. Accelerated Algebra 2 is mre rigrus than Algebra 2. Faculty Name: Office Hurs: Intrductin Cnnie Abel (BS Mathematics, MEd.) Mrs. Abel is available befre schl, during first lunch, and after schl. Appintments recmmended. Accelerated Algebra 2 is fr students wh are ready fr higher expectatins, and wuld like t take Pre- Calculus next year. Students shuld already have mastered prperties f negative numbers, fractins, expnents, radicals, slving ne and tw-step equatins, algebraic simplificatin t gather like terms, pltting tw-dimensinal crdinates, and graphing linear equatins. Level changes Students wh finish the curse with a grade f A r B will be recmmended fr Pre-Calculus. Students with a curse grade f C will be recmmended fr Technical Mathematics r Statistics and will be able t take Pre-Calculus fllwing Technical Math. Students with a curse grade f D r F will be recmmended t repeat the curse. Occasinally students wish t drp Accelerated Algebra 2 and finish the year with (nn-accelerated level) Algebra 2. Students wh change their status in this way will cntinue t have the same schedule and classrm. Mrs. Abel will differentiate the curriculum s that (nn-accelerated) Algebra 2 students will receive the same instructin but reduced rigr/expectatins in tests. NOTE: Students wh wish t make a level change must d s befre the end f the first quarter. Grading Hmewrk / frmative assessments 10% Tests / summative assessments-- 90% Grade scales regard C as prficient n unit standards, B as mastery and A as exceeding. D and F indicate failure t meet standards. Incmpletes/N-grades may be given at teacher discretin. Overall Averages A % B 80-89% C 70-79% D 60-69% F belw 60% I incmplete NG n grade Wrklad In additin t curse hurs in the classrm, students will be expected t spend 30 t 60 minutes utside f class fr hmewrk cmpletin fr every class meeting. T pass Accelerated Algebra 2, students must demnstrate prficiency in the skills listed n the last page f this dcument. These skills will be assessed in unit tests. In additin, they must either pass the state test in mathematics r pass tw wrk samples each frm a different mathematical strand. Wrk samples will be given as part f unit assessments.

2 Nte t Parents: at any time fr grade updates, questins, cncerns r cmments: abelc@hsd.k12.r.us and assignment details will be psted n Students will need a graphing calculatr, and we recmmend TI-82, TI-83, TI 84. Students will be allwed t brrw a calculatr during the class perid ONLY in exchange fr the student s ID badge. Students withut a calculatr wh d nt have their ID will be encuraged t find a friend t share. Nte: If yur child has a TI-89, TI-92 Casi-300, r any ther mdel f calculatr that has symblic slutin capabilities, please be aware that such calculatrs are nt allwed n Accelerated Algebra 2 tests. Yur student may brrw a TI-84 frm the teacher fr the test perid. Students wh d nt have adequate internet capabilities at hme will be able t use Glence cmputers and/r chrme-bks befre and after schl in the Glence Library daily, during Learning Lab (3:30-4:30 pm T, W, Th), r in rm 112 every day during first lunch. Students may als chse t use the cmputers at the public library. This curse is ffered with ptinal dual credit fr Math 95 thrugh PCC. Details, requirements and deadlines will be discussed in class. Curse Schedule (details f standards fllw belw) Curse Objectives: Students will learn t mdel, graph and slve linear, quadratic, radical, ratinal and expnential equatins using symblic, numeric and graphical methds. Students will learn the graphical prperties f the fllwing families f functins: quadratic, plynmial, radical, ratinal, expnential, lgarithmic and trignmetric. Students will be intrduced t functins, inverses, dmain and range, alng with standard ntatin fr each. Students will learn cmpund and cnditinal prbability, and unit circle trignmetry. See a cmplete list f standards belw. Make-up Wrk Plicy: Make-up wrk is frm students with excused absences, wh are allwed ne mre day than the number f days absent t cmplete and submit any assigned make-up wrk. Students in need f a make-up test will be allwed the same grace perid. On time make-up wrk receives full credit. Late Wrk Plicy: The majrity f learning takes place nt in the classrm, but during hmewrk practice. Students wh d their hmewrk prmptly have better success as well as better retentin f cncepts. Students withut cmpleted hmewrk d nt receive much-needed feedback n their effrts. Oregn Department f Educatin defines nine essential skills fr graduatin. Essential Skill number 9 is Demnstrate persnal management and teamwrk skills which includes the bullet pint, Plan, rganize and cmplete assigned tasks accurately and n time. Because hmewrk is required practice, I d nt accept late wrk. Re-take tests Retake tests are by teacher discretin nly and are reserved fr students wh have nt yet met required prficiencies. Habitual retakes will be discuraged. Students wishing t retake a test will develp a detailed, individualized plan with the teacher fr learning the missing prficiencies, fllw thrugh in a time-specified manner, and cmplete a student-reflectin n what is learned by these activities. PCC recgnizes grades ONLY frm the first attempt at each test.

3 Cheating: Cheating / plagiarism in nt tlerated and will be subject t disciplinary actin. Classrm Cnduct: All students need t cme t class with calculatr and supplies. Graph paper is required fr hmewrk. If fr any reasn, a student cmes withut a calculatr, (s)he may brrw ne frm the teacher fr the perid in exchange fr a student identificatin card. All students are expected t participate in all classrm investigatins, discussin and practice prblems. We fllw the student-parent handbk regarding dress cde, electrnic devices and tardy plicy.
