How the AK STAR reports it

AK STAR is Alaska’s state summative assessment, built around Alaska’s own mathematics standards rather than a national consortium framework. Its math blueprint is organized into grade-level content strands/instructional areas and an adaptive growth component aligned to MAP Growth instructional areas.

Blueprint & weighting

The blueprint gives target item counts and point ranges by grade and strand, rather than fixed percentage weights. Grades 3-5 and 6-9 each include summative item counts plus additional growth items; grade 9 has no summative Geometry strand, with Geometry reported only through growth items.

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.

Two angles are supplementary. One measures 15°15°. What is the other?

18015=165°180 - 15 = 165°.

A circle has a radius of 1515 feet. What is the area, in square feet, of the circle?

The area of a circle is A=πr2A = \pi r^{2}. Substitute r=15r = 15: A=π(15)2=225π.A = \pi(15)^{2} = 225\pi\textsf{.}

Find the area of a triangle with base b=4b = 4 and height h=8h = 8.

Triangle area =12bh=1248=16= \dfrac{1}{2} \cdot b \cdot h = \dfrac{1}{2} \cdot 4 \cdot 8 = 16.

A circle has diameter 88. Using π=3\pi = 3, what is its circumference?

C=πd=3×8=24C = \pi d = 3 \times 8 = 24.

What is the length of the vertical segment from (5,3)(5, -3) to (5,9)(5, 9)?

Both points have x=5x = 5, so the length is 9(3)=12|9 - (-3)| = 12.

Parallelograms EFGHEFGH and JKLMJKLM are similar. The area of parallelogram EFGHEFGH is 9,9\textsf{,} and the area of parallelogram JKLMJKLM is 36.36\textsf{.} Side EFEF corresponds to side JK,JK\textsf{,} and EF=7.EF = 7\textsf{.} What is the length of JK?JK\textsf{?}

The area ratio is 369=4=k2,\dfrac{36}{9} = 4 = k^{2}\textsf{,} so k=2.k = 2\textsf{.} Then JK=72=14.JK = 7 \cdot 2 = 14\textsf{.}

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}.
