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 27 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{.}

Between which two consecutive integers does 40\sqrt{40} lie?

62=366^{2} = 36 and 72=49.7^{2} = 49\textsf{.} Since 36<40<49,36 < 40 < 49\textsf{,} 40\sqrt{40} is between 66 and 7.7\textsf{.}

Practice playeasy

What is the slope of the line y=x−7y = 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 △JKL,\triangle JKL\textsf{,} ∠J\angle J and ∠L\angle L are congruent. The measure of each of these angles is 61.6∘.61.6^{\circ}\textsf{.} What is the measure of ∠K?\angle K\textsf{?}

The two congruent angles total 2×61.6∘=123.2∘,2 \times 61.6^{\circ} = 123.2^{\circ}\textsf{,} so ∠K=180∘−123.2∘=56.8∘.\angle K = 180^{\circ} - 123.2^{\circ} = 56.8^{\circ}\textsf{.}

{x+3y=42x+6y=8\begin{cases} x + 3y = 4 \\ 2x + 6y = 8 \end{cases}

How many solutions does the given system of equations have?

Rewrite in slope-intercept form: y=−13x+43y = -\dfrac{1}{3}x + \dfrac{4}{3} and y=−13x+43y = -\dfrac{1}{3}x + \dfrac{4}{3}. The slopes and yy-intercepts match, so the equations describe the same line and the system has infinitely many solutions.

The rule r(x)=−4x+dr(x) = -4x + d describes a linear function, and dd is a constant. If r(3)=5r(3) = 5, what is r(−2)?r(-2)\textsf{?}

Substitute x=3x = 3: −4(3)+d=5-4(3) + d = 5, so −12+d=5-12 + d = 5 and d=17d = 17. The rule is r(x)=−4x+17r(x) = -4x + 17, so r(−2)=−4(−2)+17=8+17=25r(-2) = -4(-2) + 17 = 8 + 17 = 25.
