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 circle has a radius of $15$ feet. What is the area, in square feet, of the circle?

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

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

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

A rhombus has diagonals of length $6\text{ km}$ and $14\text{ km}\textsf{.}$ What is its area?

The area of a rhombus is half the product of the diagonals: $\dfrac{1}{2} \cdot 6 \cdot 14 = 42\text{ km}^{2}\textsf{.}$

A circle has radius $5$ . Using $\pi = 3$ , what is its circumference?

$C = 2\pi r = 2 \times 3 \times 5 = 30$ .

Practice playeasy

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

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