The student als shws cnsistency thrughut his r her prject - the final prduct is neat, creative and mathematically sund. The student rganized his r her materials. Mst task sheets have been cmpleted crrectly and fully.. The student als shws cnsistency thrughut his r her prject - the final prject is primarily neat, creative, and mstly mathematically sund. The student smewhat rganized his r her materials. Sme task sheets have been cmpleted incrrectly r incmpletely. The student smewhat shws cnsistency thrughut his r her prject - the prject is neither neat nr creative, and there are mathematical errrs. The student barely rganized his r her materials. Mst f the task sheets have been cmpleted incrrectly, and are mstly incmplete. The student shws little cnsistency thrughut his r her prject - the prject is neither neat nr creative and there are mathematical errrs. The student did nt rganize his r her materials. All f the task sheets have been cmpleted incrrectly; nne are cmplete. The student shws n cnsistency thrughut his r her prject - the prject is neither neat nr creative, and it is full f mathematical errrs.
Sheet 1: Rubric The student shws clear understanding f hw t perfrm the indicated mathematical task and knwledge f the CCLS 7.RP.2. The given graph was prperly used t calculate the slpe and find the equatin f the linear functins displayed. All cmputatins are crrect and the student gave meaningful respnses regarding the relatinship between specific pints and the given real-life situatin. The student shws understanding f hw t perfrm the indicated mathematical task and knwledge f the CCLS 7.RP.2. The given graph was prperly used t calculate the slpe and find the equatin f the linear functins displayed. Mst f the cmputatins are crrect and the student gave smewhat meaningful respnses regarding the relatinship between specific pints and the given real-life situatin. The student shws sme understanding f hw t perfrm the indicated mathematical task and knwledge f the CCLS 7.RP.2. The given graph was smewhat used t calculate the slpe and find the equatin f the linear functins displayed. There are sme cmputatinal errrs and the student gave respnses regarding the relatinship between specific pints and the given real-life situatin. The student shws little understanding f hw t perfrm the indicated mathematical task and knwledge f the CCLS 7.RP.2. The graph was nt used t find the slpe and equatin f the linear functins displayed. There are multiple cmputatinal errrs and the student struggled t relate the graph t the given situatin. The student shws n understanding f hw t perfrm the indicated mathematical task and knwledge f the CCLS 7.RP.2. The slpe was nt fund and an inaccurate functin was created t describe the given situatin. There is n crrect wrk n the sheet and the student did nt relate the graph t the given situatin.
Sheet 2: Rubric The student shws clear understanding f hw t perfrm the indicated mathematical tasks and knwledge f CCLS 7.RP.2. The incrrect table and incrrect entry is identified, fully explained, and crrected. A crrect real-life scenari is prvided, alng with a crrect equatin, slpe, and graph. The student shws understanding f hw t perfrm the indicated mathematical tasks and knwledge f CCLS 7.RP.2. Mst parts f the task are crrect; an explanatin is prvided, but culd be mre detailed. A crrect real-life scenari is prvided as is a mstly crrect equatin, including slpe and graph. The student shws sme understanding f hw t perfrm the indicated mathematical tasks and an emerging knwledge f CCLS 7.RP.2. Sme parts f the task are crrect, while thers are nt. An explanatin is prvided, but is incmplete r incrrect. A real-life scenari is prvided but there are errrs with the equatin, slpe r graph. The student shws little understanding f hw t perfrm the indicated mathematical tasks and a minimal knwledge f CCLS 7.RP.2. There are multiple cmputatinal errrs and an explanatin is nt prvided. There are numerus parts f the task that are incmplete r incrrect. The student shws n understanding f hw t perfrm the indicated mathematical tasks and n knwledge f CCLS 7.RP.2. There is n crrect wrk n the sheet, nr is an explanatin, equatin, r graph prvided.
Sheet 3: Rubric The student shws clear understanding f hw t perfrm the indicated mathematical task and knwledge f the CCLS 7.RP.2. An accurate functin was created t represent the given situatin. All cmputatins are crrect and the student gave a lgical prf as t why the graphs f tw functins differ.
