4 Ratinale and Philsphy In rder t prepare fr glbal cmpetitin and high expectatins fr all, Mrris Schl District students must have increased pprtunities fr mathematical experiences that extend critical thinking and reasning. Specifically, access t higher mathematics is essential. Algebra I is a curse that prvides an imprtant entry pint fr this pathway t success by extending students understanding and applicatin f the skills, cncepts, and language f algebra. Key cnsideratins: State and Natinal Expectatins There has been great activity n the state and natinal level in terms f expectatins fr the skills, knwledge and expertise students shuld master in mathematics t succeed in wrk and life in the 21 st century. NJ is currently mving frward with the Framewrk fr 21 st Century Learning, a partnership with business, educatin, and gvernment t develp a cllective visin t strengthen American educatin ( The six cmpnents include: Cre Cntent Mathematics, 21 st Century Cntent, Learning and Thinking skills, Infrmatin and Cmmunicatins Technlgy (ICT) Literacy, Life Skills Real Wrld Applicatins, and 21 st Century Assessments. Students will be assessed n their depth f knwledge f algebra n natinal examinatins beginning in 2010, with additinal high schl mathematics curses t fllw. Equity and Access t Higher Mathematics The belief that all students, nt just a select few, have access t mathematical learning envirnments that enable them t meet wrldclass standards fr bth cllege and the wrld f wrk cntinues t be an essential gal f the Mrris Schl District. The Natinal Cuncil f Teachers f Mathematics initially reflected this imprtant cnsideratin in The Equity Principle whereby, Excellence in mathematics educatin requires equity high expectatins and strng supprt fr all students (NCTM 2000). Subsequent research has revealed that It is imprtant that high schls d everything t prmte success amng all students encuraging enrllment by students frm all demgraphics in advanced math curses. NCTM s recent release f the scientifically research-based, Fcus in High Schl Mathematics: Reasning and Sense Making (2009), stressed the rle f educatrs t help students with a wide range f backgrunds develp cnnectins between applicatins f new learning and their existing knwledge, increasing their likelihd f understanding and thereby allwing increased ptins and entry int advanced mathematics. Building n Existing Partnerships The Algebra I curse fills a critical need fr extensive study twards the develpment f abstract algebraic thinking. This gal is aligned with the district s visin f prviding rich pprtunities fr all students t mve frward n Blms Knwledge Taxnmy cntinuum frm Knwledge and Awareness t Cmprehensin, Applicatin, Analysis, Synthesis, and Evaluatin. Specifically, scafflding n a fundatin f algebra skills, this curse mves students frm the acquisitin and assimilatin f cncepts twards increased applicatin and adaptatin. Adaptatin ccurs when students have the cmpetence t think in cmplex ways and t apply their knwledge and skills. 4

5 Building n the district s existing partnerships, this curse wuld prvide a springbard fr entrance int higher level mathematics curses fr a greater number f Mrris Schl District students. [Rigr and Relevance Framewrk: Internatinal Center fr Leadership in Educatin, Bill Daggett and Ray McNulty, 5

6 Gals and Objectives (utcmes): Algebra is the study f patterns and functins. In teaching and learning Algebra I, it is imprtant fr teachers and students t cmprehend the fllwing Big Ideas and Enduring Understandings and t establish cnnectins and applicatins f the individual skills and cncepts t these brad principles as the critical gals and bjectives f the curse: Patterns and Functins Algebra prvides language thrugh which we describe and cmmunicate mathematical patterns that arise in bth mathematical and nnmathematical situatins, and in particular, when ne quantity is a functin f a secnd quantity r where the quantities change in predictable ways. Ways f representing patterns and functins include tables, graphs, symblic and verbal expressins, sequences, and frmulas. Equivalence There are many different but equivalent frms f a number, expressin, functin, r equatin, and these frms differ in their efficacy and efficiency in interpreting r slving a prblem, depending n the cntext. Algebra extends the prperties f numbers t rules invlving symbls; when applied prperly, these rules allw us t transfrm and expressin, functin, r equatin int an equivalent frm and substitute equivalent frms fr each ther. Slving prblems algebraically typically invlves transfrming ne equatin t anther equivalent equatin until the slutin becmes clear. Representatin and Mdeling with Variables Quantities can be represented by variables, whether the quantities are unknwn, changing ver time, parameters, r prbabilities. Representing quantities by variables gives us the pwer t recgnize and describe patterns, make generalizatins, prve r explain cnclusins, and slve prblems. Representing quantities with variables als enables us t mdel situatins in all areas f human endeavr and t represent them abstractly. Linearity In many situatins, the relatinship between tw quantities is linear s the graphical representatin f the relatinship is a gemetric line. Linear functins can be used t shw a relatinship between tw variables that has a cnstant rate f change and t represent the relatinship between tw quantities, which vary prprtinately. Linear functins can als be used t mdel, describe, analyze, and cmpare sets f data. Cnnectins Between Algebra & Gemetry Gemetric bjects can be represented algebraically (fr example, lines can be described using crdinates), and algebraic expressins can be interpreted gemetrically (fr example, systems f equatins and inequalities can be slved graphically). 6

7 Cnnectins Between Algebra & Systematic Cunting, Prbability, and Statistics Algebra prvides a language and techniques fr analyzing situatins that invlve chance and uncertainty, including systematic listing and cunting f all pssible utcmes (as well as infrmal explratins f Pascal s Triangle), the determinatin f their prbabilities, the calculatin f prbabilities f varius events, predicatins based n experimental prbabilities, and crrelatins between tw variables. Applicatins f Algebraic Cncepts Using the mdel, Webb s Depth-f-Knwledge Levels, Algebra I has a primary gal f increasing pprtunities fr students t reinfrce Levels 1 & 2 and t engage in Level 3 Strategic Thinking and Level 4 Extended Thinking: Strategic Thinking requires reasning, planning, using evidence, and a higher level f thinking than the previus tw levels. In mst instances, requiring students t explain their thinking is a Level 3. Activities that require students t make cnjectures are als at this level. The cgnitive demands at Level 3 are cmplex and abstract. The cmplexity des nt result frm the fact that there are multiple answers, a pssibility fr bth Levels 1 and 2, but because the task requires mre demanding reasning. An activity, hwever, that has mre than ne pssible answer and requires students t justify the respnse they give wuld mst likely be a Level 3. Other Level 3 activities include drawing cnclusins frm bservatins; citing evidence and develping a lgical argument fr cncepts; explaining phenmena in terms f cncepts; and using cncepts t slve prblems. Extended Thinking requires cmplex reasning, planning, develping, and thinking mst likely ver an extended perid f time. The extended time perid is nt a distinguishing factr if the required wrk is nly repetitive and des nt require applying significant cnceptual understanding and higher-rder thinking. Fr example, if a student has t take the water temperature frm a river each day fr a mnth and then cnstruct a graph, this wuld be classified as a Level 2. Hwever, if the student is t cnduct a river study that requires taking int cnsideratin a number f variables, this wuld be a Level 4. At Level 4, the cgnitive demands f the task shuld be high and the wrk shuld be very cmplex. Students shuld be required t make several cnnectins relate ideas within the cntent area r amng cntent areas and have t select ne apprach amng many alternatives n hw the situatin shuld be slved, in rder t be at this highest level. Level 4 activities include designing and cnducting experiments; making cnnectins between a finding and related cncepts and phenmena; cmbining and synthesizing ideas int new cncepts; and critiquing experimental designs.

14 Teaching/Learning Activities The Standards fr Mathematical Practice describe varieties f expertise that mathematics educatrs at all levels shuld seek t develp in their students thrugh teaching and learning activities. A secndary dcument [Curriculum Map: Algebra I], has been prepared t prvide greater detail as t specific teaching/learning activities fr this curse. Teaching/Learning practices rest n imprtant prcesses and prficiencies with lngstanding imprtance in mathematics educatin. The first f these are the NCTM Prcess Standards f prblem slving, reasning and prf, cmmunicatin, representatin, and cnnectins. The secnd are the strands f mathematical prficiency specified in the Natinal Research Cuncil s reprt Adding It Up: adaptive reasning, strategic cmpetence, cnceptual understanding (cmprehensin f mathematical cncepts, peratins and relatins), prcedural fluency (skill in carrying ut prcedures flexibly, accurately, efficiently and apprpriately), and prductive dispsitin (habitual inclinatin t see mathematics as sensible, useful, and wrthwhile, cupled with a belief in diligence and ne s wn efficacy). The teaching/learning activities in Algebra I are fcused n develping the fllwing mathematical prficiencies: 1. Make sense f prblems and persevere in slving them. Mathematically prficient students start by explaining t themselves the meaning f a prblem and lking fr entry pints t its slutin. They analyze givens, cnstraints, relatinships, and gals. They make cnjectures abut the frm and meaning f the slutin and plan a slutin pathway rather than simply jumping int a slutin attempt. They cnsider analgus prblems, and try special cases and simpler frms f the riginal prblem in rder t gain insight int its slutin. They mnitr and evaluate their prgress and change curse if necessary. Older students might, depending n the cntext f the prblem, transfrm algebraic expressins r change the viewing windw n their graphing calculatr t get the infrmatin they need. Mathematically prficient students can explain crrespndences between equatins, verbal descriptins, tables, and graphs r draw diagrams f imprtant features and relatinships, graph data, and search fr regularity r trends. Mathematically prficient students check their answers t prblems using a different methd, and they cntinually ask themselves, Des this make sense? They can understand the appraches f thers t slving cmplex prblems and identify crrespndences between different appraches. 2. Reasn abstractly and quantitatively. Mathematically prficient students make sense f quantities and their relatinships in prblem situatins. They bring tw cmplementary abilities t bear n prblems invlving quantitative relatinships: the ability t decntextualize t abstract a given situatin and represent it symblically and manipulate the representing symbls as if they have a life f their wn, withut necessarily attending t their referents and the ability t cntextualize, t pause as needed during the manipulatin prcess in rder t prbe int the referents fr the symbls invlved. Quantitative reasning entails habits f creating a cherent representatin f the prblem at hand; cnsidering the units invlved; attending t the meaning f quantities, nt just hw t cmpute them; and knwing and flexibly using different prperties f peratins and bjects. 14

15 3. Cnstruct viable arguments and critique the reasning f thers. Mathematically prficient students understand and use stated assumptins, definitins, and previusly established results in cnstructing arguments. They make cnjectures and build a lgical prgressin f statements t explre the truth f their cnjectures. They are able t analyze situatins by breaking them int cases, and can recgnize and use cunterexamples. They justify their cnclusins, cmmunicate them t thers, and respnd t the arguments f thers. They reasn inductively abut data, making plausible arguments that take int accunt the cntext frm which the data arse. Mathematically prficient students are als able t cmpare the effectiveness f tw plausible arguments, distinguish crrect lgic r reasning frm that which is flawed, and if there is a flaw in an argument explain what it is. Elementary students can cnstruct arguments using cncrete referents such as bjects, drawings, diagrams, and actins. Such arguments can make sense and be crrect, even thugh they are nt generalized r made frmal until later grades. Later in algebra, students learn t determine dmains t which an argument applies. Students at all grades can listen r read the arguments f thers, decide whether they make sense, and ask useful questins t clarify r imprve the arguments. 4. Mdel with mathematics. Mathematically prficient students can apply the mathematics they knw t slve prblems arising in everyday life, sciety, and the wrkplace. In early algebraic reasning, this might be as simple as writing an additin equatin t describe a situatin. In middle grades, a student might apply prprtinal reasning t plan a schl event r analyze a prblem in the cmmunity. By high schl, a student might use gemetry t slve a design prblem r use a functin t describe hw ne quantity f interest depends n anther. Mathematically prficient students wh can apply what they knw are cmfrtable making assumptins and apprximatins t simplify a cmplicated situatin, realizing that these may need revisin later. They are able t identify imprtant quantities in a practical situatin and map their relatinships using such tls as diagrams, twway tables, graphs, flwcharts and frmulas. They can analyze thse relatinships mathematically t draw cnclusins. They rutinely interpret their mathematical results in the cntext f the situatin and reflect n whether the results make sense, pssibly imprving the mdel if it has nt served its purpse. 5. Use apprpriate tls strategically. Mathematically prficient students cnsider the available tls when slving a mathematical prblem. These tls might include pencil and paper, cncrete mdels, a ruler, a prtractr, a calculatr, a spreadsheet, a cmputer algebra system, a statistical package, r dynamic gemetry sftware. Prficient students are sufficiently familiar with tls apprpriate fr their grade r curse t make sund decisins abut when each f these tls might be helpful, recgnizing bth the insight t be gained and their limitatins. Fr example, mathematically prficient high schl students analyze graphs f functins and slutins generated using a graphing calculatr. They detect pssible errrs by strategically using estimatin and ther mathematical knwledge. When making mathematical mdels, they knw that technlgy can enable them t visualize the results f varying assumptins, explre cnsequences, and cmpare predictins with data. Mathematically prficient students at varius grade levels are able t identify relevant external mathematical resurces, such as digital cntent lcated n a website, and use them t pse r slve prblems. They are able t use technlgical tls t explre and deepen their understanding f cncepts. 15

16 6. Attend t precisin. Mathematically prficient students try t cmmunicate precisely t thers. They try t use clear definitins in discussin with thers and in their wn reasning. They state the meaning f the symbls they chse, including using the equal sign cnsistently and apprpriately. They are careful abut specifying units f measure, and labeling axes t clarify the crrespndence with quantities in a prblem. They calculate accurately and efficiently, express numerical answers with a degree f precisin apprpriate fr the prblem cntext. Initially, students give carefully frmulated explanatins t each ther. By the time they reach high schl they have learned t examine claims and make explicit use f definitins. 7. Lk fr and make use f structure. Mathematically prficient students lk clsely t discern a pattern r structure. Students will see 7 8 equals the well remembered , in preparatin fr learning abut the distributive prperty. In the expressin x 2 + 9x + 14, algebra students can see the 14 as 2 7 and the 9 as They recgnize the significance f an existing line in a gemetric figure and can use the strategy f drawing an auxiliary line fr slving prblems. They als can step back fr an verview and shift perspective. They can see cmplicated things, such as sme algebraic expressins, as single bjects r as being cmpsed f several bjects. Fr example, they can see 5 3(x y) 2 as 5 minus a psitive number times a square and use that t realize that its value cannt be mre than 5 fr any real numbers x and y. 8. Lk fr and express regularity in repeated reasning. Mathematically prficient students ntice if calculatins are repeated, and lk bth fr general methds and fr shrtcuts. By paying attentin t the calculatin f slpe as they repeatedly check whether pints are n the line thrugh (1, 2) with slpe 3, algebra students might abstract the equatin (y 2)/(x 1) = 3. Nticing the regularity in the way terms cancel when expanding (x 1)(x + 1), (x 1)(x 2 + x + 1), and (x 1)(x 3 + x2 + x + 1) might lead them t the general frmula fr the sum f a gemetric series. As they wrk t slve a prblem, mathematically prficient students maintain versight f the prcess, while attending t the details. They cntinually evaluate the reasnableness f their intermediate results. 16

17 Assessment and Testing Strategies Sund and prductive classrm assessments are built n a fundatin f the fllwing five key dimensins (Stiggins et al, 2006): Key 1: Assessment serves a clear and apprpriate purpse. Did the teacher specify users and uses, and are these apprpriate? Key 2: Assessment reflects valued achievement targets. Has the teacher clearly specified the achievement targets t be reflected in the exercises? D these represent imprtant learning utcmes? Key 3: Design. Des the selectin f the methd make sense given the gals and purpses? Is there anything in the assessment that might lead t misleading results? Key 4: Cmmunicatin. Is it clear hw this assessment helps cmmunicatin with thers abut student achievement? Key 5: Student Invlvement. Is it clear hw students are invlved in the assessment as a way t help them understand achievement targets, practice hitting thse targets, see themselves grwing in their achievement, and cmmunicate with thers abut their success as learners? The Algebra I curse will include a variety f assessment tls fr the effective teaching and learning f mathematics. In additin t classrm and district assessments, students will demnstrate prficiency f algebraic reasning and skills n the New Jersey Algebra I State-wide Assessment as required fr graduatin. Indicatrs f Sund Classrm Assessment Practice will cnsist f bth frmative and summative assessments that may include, but are nt limited t: Observatin Interviews Prtflis (Prject, Grwth, Achievement, Cmpetence, Celebratin) 17
