UNDERSTANDING BY DESIGN UNIT PLANSTAGE 3: THE LEARNING/FORMATIVE ASSESSMENT PLAN (USE AS MANY ROWS AS NECESSARY)Lesson # &Topic/FocusLesson 1:ParentFunctions andVertical Shiftsf(x) kUKDs (You caninclude #sfrom Stage 1)U2, K1, K2, K4,D1, D2Concrete GROUP Formative Assessments(Thoroughly Describe and/or Attach)Concrete INDIVIDUAL Formative Assessments(Thoroughly Describe and/or Attach)This lesson will start out with an introductionto what function transformations are. This willinvolve learning what parent functions are andhow to identify them. Once this material isintroduced the students will play the gameMemory Match with parent functions. Theteacher will randomly sort students intogroups of 2-3. The deck of memory matchcards given to each group will have variousgraphs drawn on half and the labels linear,quadratic, exponential, and logarithmic on theother half. Students will lay all the cards facedown and take turns flipping two cards over ata time. If they flip over a graph and itscorresponding parent function (linear,quadratic, exponential, or logarithmic) thenthey have a match and get to go again! If it isnot a match then the next student takes aturn. While the games are occurring theteacher will walk around making note of whichmatches students are struggling with themost. When a group completes a game theymust raise their hands so that the teacher cancheck that all their matches are accurate. Ifthere are errors they will be told to work as agroup to find and correct the errors so that allmatches are accurate. If there are no errorsor they have fixed them all and there is stilltime, they will be provided with a new deck.The teacher will have multiple decks ofincreasing difficulty so that groups that areprogressing quicker with the concept andgame can develop a deeper understanding.At the end of the lesson students will completean exit slip that is an altered form of a FrayerDiagram. This will assess their understanding ofvertical shifts and their ability to work withvertical shifts by asking them to produceexamples and non-examples. It will also bring inthe topic of parent functions by having themidentify the parent functions that go with theirexamples. Based on how students do with thiswill determine how the next lesson will begin. Ifthere is confusion on parent functions, that willneed to be addressed before the teacher cancontinue on with teaching more transformations.If there are difficulties with vertical shifts, thenthe next lesson will begin with white boardpractice with vertical shifts to help students getmore comfortable with the concept and havemore practice time.Understanding by Design 2.0 - Wiggins and McTighe, 2011

UNDERSTANDING BY DESIGN UNIT PLANLesson 2:VerticalStretches/Compressionskf(x)U2, K2, K5, K6,D1, D2, D3, D4Lesson 3:Horizontal Shiftsf(x k)U1, U2, K1, K3,D3, D4After the teacher gives an introduction tovertical shifts and compressions and worksthrough some examples with the class on theboard, the will do a White Board activity.This will begin with the teacher writing afunction on the board that includes verticalshifts (from lesson 1) and/or vertical stretchesand compressions. Students will sketch thegraph on their white boards (which will havecoordinate planes on them) and then holdthem up for the teacher to see. While they aresketching the teacher will walk around andobserve how the students are doing with thesketching process to help determine if acertain type needs more practice (this willguide what functions they try to graph nextand how quickly the difficulty of the functionswill increase). After the students begin tograsp the ability to graph these verticaltransformations, the teacher will give them asecond marker in a different color. This timethey will graph two functions at the same timeto see how changing the constant affects the2graph. For example: graphing f(x) x 6 and22f(x) x -6 or graphing f(x) 3x and f(x) 2(1/3)x .At the end of this lesson the class will do aGraffiti Wall to help tie together all thetransformations covered so far and bring inthe order to apply them. Students will bedivided into 8 groups (probably 2-3 people pergroup). There will be 4 graphs (one linear,one quadratic, one exponential, and onelogarithmic) on large sheets of paper alongone wall and the same four along the oppositewall. Each group will be assigned to a startinggraph and a colored marker and will thenrotate among the four graphs on their side ofthe room. The instructions (which will beshown via a PowerPoint one step at a time)will be:At the end of the lesson students will completean Exit Slip. This exit slip will allow students todisplay their understanding of vertical stretchesand compressions via words and pictures aswell as practice with graphing a vertical stretch.Finally, it asks students to determine thefunction from a picture of a graph with a verticalcompression. It is important for students to bothbe able to produce the graphs and deduce thefunction from a graph to ensure a completeunderstanding of vertical stretches andcompressions. The results of this exit slip willbe used to determine if any review or reteaching needs to occur prior to continuing ontothe next topic.At the end of the lesson, students will completean Exit Slip. This exit slip will check in on theirunderstanding of transformations as a whole,have them practice explaining the concept tosomeone else, and have them deduce a functionfrom a graph that includes a horizontal shift.Asking students to explain the steps is veryimportant for this topic because many studentsfall trap to common misconceptions abouthorizontal shifts. By asking them to explain itwill allow the teacher to see if they know why“ k” means go k units to the left (not the right!).If they can understand why it happens then theyare much more likely to not make the commonmistake than if they just know that the algorithmUnderstanding by Design 2.0 - Wiggins and McTighe, 2011

Check and make corrections to anyprior work. Then number thetransformations in the order you thinkthey were applied.While students are working on this, theteacher will walk around to answer questionsand observe the work students are doing. Ifthere are errors in the work, the teacher willstep in and ask some probing questions to getstudents back on track.Once students complete this they will presenttheir graph (the one they ended at) to thegroup. Since there are two of each graph, thegroups that have the same ones will presentback to back so that comparisons can bemade. If there are still errors in thepresentation stage, then the class will worktogether to correct them with guidance fromthe teacher when necessary.This Graffiti Wall serves to bring together allthe information covered so far and see howstudents are doing putting it all together.After the teacher gives the introduction tohorizontal stretches and compressions,students will practice with a White Boardactivity. This will begin similarly to the whitetells them to go left for positive numbers. Theresults of this exit slip will be used to determineif students need more practice with horizontalshifts, specifically understanding how and whythey work, before continuing onto verticalstretches and compressions (especially sincethis is also another topic which many studentsmix up).At the end of the lesson, students will completean Exit Slip. This exit slip will check in withwhere students are with all of the horizontaltransformations covered so far by having themUnderstanding by Design 2.0 - Wiggins and McTighe, 2011

UNDERSTANDING BY DESIGN UNIT PLANCompressionsf(kx)Lesson 5:U1, U2, K1, K3-board activity from lesson 2 with the teacherwriting down functions on the board thatinclude horizontal shifts, stretches, andcompressions and the students drawing it ontheir white boards and holding them up. Aftera few practice problems as a whole class tomake sure everyone has the idea, the teacherwill divide students up into groups based onthe readiness they have displayed in the firstfew examples and throughout the unit so far(specifically with graphing thetransformations). The teacher will have threelists of functions prepared – each of whichincreases in difficulty at a different pace.Each of these lists includes all the horizontaltransformations for each of the four types offunctions (linear, quadratic, exponential, andlogarithmic). The more challenging list willinclude functions that include multipletransformations and bring in all the verticaltransformations as well. The less challengingone will begin with only one transformation ata time and slowly lead up to incorporatingmultiple. The one in the middle will focusmostly on functions with two transformationsand towards the end a couple with three orfour.In these groups students will work together tograph each of the functions on their list. Aworksheet will be provided as well for themto record their answers on after they haveworked them out on the white board. Theteacher will be randomly collecting oneworksheet from each group so all studentsmust be filling it out.The teacher will cycle around to the groupsanswering questions, listening to discussions,and asking probing questions to get them onthe right track.This lesson will begin with an introduction toreflections (which are a special type ofcomplete a Venn Diagram comparing andcontrasting them. It then has students practicespecifically with the horizontal stretches andcompressions taught that day by having themcompose a function from given transformationsand then graph it. Since horizontalcompressions and stretches are also a commonplace where students can fall trap tomisconceptions, they are asked at the end toexplain why what they are given is a stretch andnot a compression. Based on these exit slips,the teacher will decide if more practice withhorizontal transformations is needed beforemoving on. Specifically, the teacher will belooking for if students are falling trap to themisconception or not. If they are, then thiswould be an important thing to address throughmore activities and practice with horizontalstretches and compressions before moving on.This lesson focused on combining all thetransformations together. So at the end of theUnderstanding by Design 2.0 - Wiggins and McTighe, 2011

Afterthis, students will have been exposed to allthe different transformations covered in theunit so it would be beneficial to check in ontheir understanding of the concept oftransformations by seeing how students woulddefine a transformation. This will be donethrough a Think/Pair/Share. First studentswill be instructed to think about and writedown in their notebooks how they woulddefine a transformation. Next, they wouldshare their definitions with their elbow partnerand together create a new definition they bothagree on. Finally, the class as a whole woulddiscuss it and come up with a final definitionto hang up in the classroom. This discussionwill give insight to the teacher on how wellthey have grasped the concepts oftransformations and what can be considered atransformation. Based on how studentsdiscussion goes will determine how much theteacher must intervene to further explain theconcept or provide probing questions.lesson, the Exit Slip is going to be similar to thematrix done during class, but then take it onestep further and have students order and applythe transformations by graphing them one stepat a time. Finally, the last question on this exitslip allows students to reflect on how doing thisprocess helps them (or does not help them).This allows the teacher to see both how theylearn and helps the students to self-reflect onwhat works best for them. The responses to thisexit slip will help to determine how much morepractice with transformations is needed beforestudents are ready to applying them to realworld data. If students are still struggling (basedon results from both this exit slip and the groupformative assessment from this day), then moreactivities and white board practice will beincluded at the beginning of the next day. It isvery important for students to be able to pull allthe transformations together before they moveonto curve of best fit, which will require them tochoose and apply the appropriatetransformations.A second group formative assessment will bedone this lesson to help students practicewith identifying each of the transformationsthat different functions are composed of. Thiswill be done with a Matrix Activity. Studentswill be divided into groups of 3-4 students tocomplete the matrix. The teacher will walkaround to answer questions and provideprobing questions to get students on track ordeepen their understanding. If a groupfinishes early, they will be provided with whiteboards to then practice graphing each of thefunctions on the matrix. If time permits, eachgroup will get to graph at least somefunctions on the white boards.This last lesson focuses on the topic of thecurve of best fit and interpolating.

UNDERSTANDING BY DESIGN UNIT PLANLesson 6;Curve of Best FitandInterpolatingD5, D6these directly relate to working with real worlddata. To practice identifying the curve of bestfit for real world data, students will partake ina Closed Sort. They will be randomly dividedinto groups of 2-3 students. Each group willbe given notecards that have either a table ofdata or a scatter plot representing real worlddata. The groups will then sort the notecardsinto the groups: linear, quadratic,exponential, and logarithmic. This means theywould be sorting the notecards based onwhich type of function would be used to makethe curve of best fit.Once a group completes the sort, they willcompare with another group who is finishedand discuss why they put each notecard in thecategory they chose. Some notecards will beable to go in multiple categories so it’simportant for the students to both be able toback up why they chose one over the otherand also be able to understand that there canbe more than one option as long as it isappropriately supported.After this, each group will pick one of thenotecards from each of their four categoriesand come up with a function (including sometransformations) that would be an appropriatecurve of best fit. Each notecard will also havea number in the upper right hand corner.Student will then use the function theyproduced to interpolate for the value writtenin that top right corner. They will write theirfunction, show their work for interpolating,and write a sentence interpreting what theirresult means for the set of data on the backof the notecard. These notecards will becollected by the teacher at the end of thelesson.Throughout this activity the teacher will becycling around to check in on how studentsare doing and listen to their discussions.curve of best fit and interpolating, students willcomplete an Exit Slip.
