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).

Which expression is equivalent to $p + 12 + 5$ ?

The constants $12$ and $5$ are like terms: $12 + 5 = 17$ . The term $p$ stays the same, so the expression is equivalent to $p + 17\textsf{.}$

Simplify: $8x + 2 + 8x - 1$ .

Combine $x$ -terms: $8x + 8x = 16x$ . Combine constants: $2 - 1 = 1$ . Result: $16x + 1$ .

Which expression is equivalent to $\sqrt{54}+\sqrt{24}$ ?

$\sqrt{54}=\sqrt{9 \cdot 6}=3\sqrt{6}$ and $\sqrt{24}=\sqrt{4 \cdot 6}=2\sqrt{6}$ . Adding like radical terms gives $3\sqrt{6}+2\sqrt{6}=5\sqrt{6}$ .

A hiking sign lists the distance to a waterfall as $4{,}500$ meters. How many kilometers is that? ( $1$ kilometer $= 1{,}000$ meters)

Use a conversion factor with kilometers in the numerator so meters cancel: $4{,}500 \text{ m} \times \dfrac{1 \text{ km}}{1{,}000 \text{ m}} = 4.5 \text{ km}$ .
