OR SBAC Grade 11 Concepts and Procedures Practice

OR SBAC Grade 11 Concepts and Procedures. Practice it free.

Students can explain and apply mathematical concepts and interpret and carry out mathematical procedures with precision and fluency. Targets are the 2021 Oregon K-12 Math Standards' condensed high school clusters (Oregon's HS codes replace the consortium's 16 letter targets); the 2025-26 blueprint draws 13 of the grade 11 CAT's 22 items from these targets — 9 from priority target sets, 4 from supporting. HS.GM.A and HS.GM.B are new 2021-standards targets the blueprint marks as assessed in a future year (0 items in 2025-26). This Grade 11 reporting domain maps to 84 practice skills and 8 representative questions from the playable bank.

Standards basis

2021 Oregon K-12 Math Standards (CCSS-M-derived Oregon standards, with renamed domains and an added Data Reasoning strand) — Oregon

How the OR SBAC reports it

Oregon's statewide summative math test — part of OSAS, the Oregon Statewide Assessment System (the landing slug keeps the legacy OAKS name) — is developed through Smarter Balanced: a computer-adaptive test plus a performance task, organized into the four Smarter Balanced claims. Since aligning to the 2021 Oregon K-12 Math Standards, Oregon publishes its own blueprint rather than the consortium's: Claim 1 assessment targets carry Oregon cluster codes with renamed/regrouped domains (GM geometric measurement and DR data reasoning replace MD and SP; AEE and AFN replace EE and F; grade 7 probability moves to 7.RP.B), each cross-referenced to its former Smarter Balanced letter target, plus new Oregon-developed Data Reasoning targets field tested in 2024-25. Claims 2-4 keep the Smarter Balanced process targets (Claim 4 without the consortium's Target G, and Claim 3 Target G appearing on the grade 6-8 and 11 blueprints only). Claim 1 targets are grouped into priority and supporting target sets with published per-set item counts.

Blueprint & weighting

OSAS Summative Mathematics Test Blueprints (2025-26, last updated 12/22/2025): each grade's CAT draws 10 Claim 1 items in grades 3-8 (7 from priority target sets and 3 from supporting; 6 and 4 in grade 5) and 13 in grade 11 (9 priority, 4 supporting), 3 items from combined Claims 2 and 4, 4 Claim 3 items, and 2 unscored field-test items — 19 CAT items total in grades 3-8, 22 in grade 11. The performance task adds 4-6 items: 1-2 Claim 2, 0-2 Claim 3, 1-3 Claim 4, and no Claim 1 items (PTs assess the practice standards, drawing scenarios from across Claim 1 content domains). Per-target-set item counts are published in the blueprint tables; no percentage weighting is published.

For which value of $x$ does the graph of $y = -(x + 8)(x - 2)$ meet the $x$ -axis?

Set $y = 0$ : $-(x + 8)(x - 2) = 0$ . The factor $-1$ is nonzero, so the zeros come from $x + 8 = 0 \Rightarrow x = -8$ and $x - 2 = 0 \Rightarrow x = 2$ . Of the choices, $-8$ is an x-coordinate of an x-intercept.

$f(x) = 4(x + 1)^2 - 3$

The function $f$ is defined by the given equation. For what value of $x$ does $f(x)$ reach its minimum?

The equation is in vertex form $f(x) = a(x - h)^2 + k$ with $a = 4 > 0$ , so the graph opens upward and the minimum occurs at the vertex. Rewrite $(x + 1)^2$ as $(x - (-1))^2$ : the vertex is at $x = -1$ . The leading coefficient $4$ does not change the $x$ -coordinate of the vertex. Therefore, $f(x)$ reaches its minimum when $x = -1$ .

The equation below defines $y$ as a function of $x$ . At what value of $x$ is $y$ smallest?

$y = x^2 - 6x + 5$

The parabola opens upward, so the smallest $y$ is at the vertex. For $y = ax^2 + bx + c$ , the $x$ -value at the vertex is $x = -\dfrac{b}{2a}$ . Here $a = 1$ and $b = -6$ , so $x = -\dfrac{-6}{2(1)} = \dfrac{6}{2} = 3$ . Therefore, $y$ is smallest when $x = 3$ .

An online store's weekly visitors are modeled by $v(w)=1{,}250(1.08)^w$ , where $w$ is the number of weeks after a launch campaign begins. According to the model, how many visitors does the store have $2$ weeks after the campaign begins?

Substitute $w=2$ : $v(2)=1{,}250(1.08)^2=1{,}250(1.1664)=1{,}458$ .

Find the volume of a cone with radius $3$ and height $5$ . Use $\pi = 3$ .

$V = \dfrac{1}{3}\pi r^2 h = \dfrac{1}{3} \times 3 \times 9 \times 5 = 45$ .

$|x + 8| = 21$

Which of the following gives both solutions to the given equation?

The equation means $x + 8 = 21$ or $x + 8 = -21$ . So $x = 13$ or $x = -29$ . Both solutions are $-29$ and $13\textsf{.}$

Practice playeasy

If $|2x + 10| = 26$ , what is the positive value of $x + 5$ ?

Rewrite $|2x + 10| = |2(x + 5)| = |2|\,|x + 5| = 2|x + 5|$ . Since $2|x + 5| = 26$ , divide by $2$ to get $|x + 5| = 13$ . The expression $x + 5$ equals $13$ or $-13$ ; the positive value is $13\textsf{.}$

Practice playmedium

In $\triangle GHI$ , $m\angle G=(2x+5)°$ , $m\angle H=(3x+5)°$ , and $m\angle I=(x+50)°$ . What is the measure of the largest angle of the triangle?

The angles sum to $180°$ : $(2x+5)+(3x+5)+(x+50)=180$ , so $6x+60=180$ and $x=20$ . The angles are $45°$ , $65°$ , and $70°$ , so the largest is $70°$ .
