Nevada SBAC Grade 8 Concepts and Procedures. Practice it free.

Students can explain and apply mathematical concepts and interpret and carry out mathematical procedures with precision and fluency. Content is drawn from the Grade 8 clusters listed as targets below, with a much greater proportion from clusters the blueprint designates as priority (major) clusters. This Grade 8 reporting domain maps to 26 practice skills and 8 representative questions from the playable bank.

How the Nevada SBAC reports it

Nevada administers the consortium Smarter Balanced mathematics summative assessment in grades 3-8 (Nevada Department of Education, Office of Assessments); grade 11 students take the ACT as Nevada's college and career readiness assessment, so the state has no high-school Smarter Balanced administration. The test uses the consortium's shared structure: Claim 1 (Concepts and Procedures) publishes per-grade assessment targets that are verbatim CCSS-M cluster headings; Claims 2-4 are cross-cutting process claims whose targets are constant across grades and draw on the same grade-level content. On score reports, Claims 2 and 4 are combined into a single reporting category, so three claim scores accompany the overall math score.

Blueprint & weighting

Content Specifications (Reporting Categories section): the total mathematics score is a weighted composite of the four claims — Claim 1 (Concepts and Procedures) contributes roughly 50%, Claim 3 (Communicating Reasoning) roughly 25%, and combined Claims 2 and 4 (Problem Solving / Modeling and Data Analysis) about 25%. The summative blueprint (as of 2018-19) publishes item counts per test event rather than percentages: Claim 1 is 17-20 items in grades 3-5 and 16-20 in grades 6-8; the Claim 2/4 and Claim 3 reporting categories are 8-10 items each, totaling 18-20 across the two.

A cylinder has radius 22 and height 44. Using π=3\pi = 3, what is its volume?

V=πr2h=3×4×4=48V = \pi r^2 h = 3 \times 4 \times 4 = 48.

What is the yy-intercept of the graph of y=15x+4y = 15x + 4 in the coordinate plane?

In y=mx+by = mx + b, the yy-intercept is the point (0,b)(0, b). Here b=4b = 4, so the yy-intercept is (0,4).(0, 4)\textsf{.}

27\sqrt{27} lies between two consecutive integers. Enter the larger one.

52=25<27<36=625^2 = 25 < 27 < 36 = 6^2, so 27\sqrt{27} is between 55 and 66; the larger is 66.

Simplify: b8b4\dfrac{b^{8}}{b^{4}}.

The Quotient of Powers Property says that powers with the same nonzero base are divided by subtracting the exponents, written bmbn=bmn.\dfrac{b^{m}}{b^{n}} = b^{m-n}\textsf{.} Here both the numerator and the denominator have base bb, so b8b4=b84=b4.\dfrac{b^{8}}{b^{4}} = b^{8-4} = b^{4}\textsf{.}

Let f(t)=3e2t+10f(t) = 3e^{2t} + 10. Which of the following approximations, written as a×10na \times 10^n with one significant digit, is closest to the value of f(5)f(5)?

Substitute t=5t = 5: f(5)=3e10+10f(5) = 3e^{10} + 10. Since e1022,026e^{10} \approx 22{,}026, f(5)3(22,026)+10=66,0887×104f(5) \approx 3(22{,}026) + 10 = 66{,}088 \approx 7 \times 10^{4}.

What is the slope of the line y=x7y = x - 7?

In y=mx+by = mx + b, the slope is m=1m = 1.

Practice playeasy

Which system of equations has no solution?

Both equations have slope 66 but different yy-intercepts (11 and 4-4), so the lines are parallel and the system has no solution.

In LMN\triangle LMN, L\angle L and N\angle N are congruent. Each of these angles measures 38.238.2^{\circ}. What is the measure of M\angle M?

Together the congruent angles measure 2×38.2=76.42 \times 38.2^{\circ} = 76.4^{\circ}, so M=18076.4=103.6\angle M = 180^{\circ} - 76.4^{\circ} = 103.6^{\circ}.
