How the Star Math reports it

Star Math is Renaissance’s proprietary adaptive assessment, not a shared framework like SBAC or NAEP. The page describes research-based, state-specific learning progressions aligned to English and Spanish, rather than a single common external blueprint.

Blueprint & weighting

Star Math uses the Independent / state-specific framework (strands structure).

A rectangular prism has volume $160$ cubic inches and height $5$ inches. The length is twice the width. What is the length, in inches?

$V = \ell w h$ and $\ell = 2w$ , so $160 = (2w)(w)(5) = 10w^2$ . Then $w^2 = 16$ , so $w = 4$ and $\ell = 8\text{ in}\textsf{.}$

A rectangular pyramid tent has a $10$ -foot-by- $4$ -foot rectangular base. The two triangular faces along the $10$ -foot sides each have slant height $6$ feet, and the two triangular faces along the $4$ -foot sides each have slant height $5$ feet. The tent has no floor. What is the exterior surface area, in square feet, of the tent fabric?

Without a floor, only the four triangular faces are counted. Along the $10$ -foot sides: $2 \times \dfrac{1}{2}(10)(6) = 60$ . Along the $4$ -foot sides: $2 \times \dfrac{1}{2}(4)(5) = 20$ . The total is $60 + 20 = 80$ square feet.

Find the volume of a cone with radius $2$ and height $9$ . Use $\pi = 3$ .

$V = \dfrac{1}{3}\pi r^2 h = \dfrac{1}{3} \times 3 \times 4 \times 9 = 36$ .

A cylinder has radius $2$ and height $4$ . Using $\pi = 3$ , what is its volume?

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

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

$180 - 15 = 165°$ .

Practice playeasy

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 $r = 15$ : $A = \pi(15)^{2} = 225\pi\textsf{.}$

Practice playeasy

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

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