8(x + 3) was determined. 5 a – b A-SSE.2 Student was unable to respond to many of the questions, or student left several items blank. Student was only able to come up with one option for part (a) and, therefore, had only partial work for part (b), OR student answered “Yes” for the question about equivalent expressions. Student successfully answered part (a) and identified that the expressions created in part (b) were not equivalent, but there were minor errors in the answering of the remaining questions. Student answered all four parts correctly and completely. 6 a A-SSE.2 Student left at least three items blank, or student answered at least three items incorrectly. Student answered one or two items incorrectly or left one or more items blank. Student completed circling task correctly, and provided a correct ordering of symbols in the box, but the answer did not use parentheses or multiplication dots. Student completed all four item correctly, including exact placement of parentheses AND symbols for the box: . b A-SSE.2 Student did not complete either proof successfully. Student attempted both proofs but made minor errors in both, or student only completed one proof, with or without errors. Student attempted both proofs but made an error in one of them. Student completed both proofs correctly, and the two proofs were different from one another.
