How the ISAT reports it

Idaho ISAT is a state assessment administered to grades 3–8 and 11 and reported against Idaho grade-level content standards rather than a separate national testing framework. The public ISAT page points to summative blueprints and math specifications, while the Idaho Content Standards page shows the math program is organized by grade-band/domain progressions aligned to Idaho standards.

Blueprint & weighting

The public Idaho ISAT page references summative blueprints and item specifications, but the accessible official page content did not expose a published domain-by-domain percentage blueprint for math.

Which is the completely factored form of $9x^{2} - 6x$ ?

The greatest common factor of $9x^{2}$ and $6x$ is $3x\textsf{.}$ Factoring gives $3x(3x - 2)$ .

A shipping label allows a package weight $w$ , in pounds, that is more than $2$ pounds but at most $10$ pounds. Which inequality represents the possible values of $w$ ?

More than $2$ means $w > 2$ . At most $10$ means $w \le 10$ , so $2 < w \le 10$ .

A concert sells $s$ student tickets and $a$ adult tickets. There are $2$ times as many student tickets as adult tickets, and $27$ tickets are sold in all. Which system of equations represents this situation?

There are $2$ times as many student tickets as adult tickets, so $s = 2a\textsf{.}$ In all there are $27$ tickets, so $s + a = 27\textsf{.}$

Which expression is equivalent to $4x^{2} - 81$ ?

$4x^{2} - 81 = (2x)^{2} - 9^{2} = (2x - 9)(2x + 9)$ .

Practice playeasy

Which expression is equivalent to $\dfrac{50x}{h} + 50x$ , where $h > 0$ ?

Write $50x$ with denominator $h$ : $\dfrac{50x}{h} + \dfrac{50xh}{h} = \dfrac{50x + 50xh}{h} = \dfrac{50x(h + 1)}{h}$ .

Practice playeasy

Which expression is equivalent to $x^2 + 2x - 15$ ?

Find two numbers with product $-15$ and sum $2$ : $5$ and $-3$ . So $x^2 + 2x - 15 = (x+5)(x-3)$ .

Practice playeasy

$x^3 - 27 = 0$ . What is the real root?

$x^3 - 27 = (x - 3)(x^2 + 3x + 9) = 0$ . The quadratic factor has no real roots, so the only real root is $x = 3$ .

Practice playeasy

Factor: $12x^{2} + 8x$ .

The greatest common factor of $12x^{2}$ and $8x$ is $4x$ . So $12x^{2} + 8x = 4x(3x + 2)$ .
