Standards basis

Common Core State Standards for Mathematics (CCSS-M) / New Hampshire mathematics standards — New Hampshire

How the NH SAS reports it

New Hampshire SAS is the state assessment system, but the official math reporting structure was not accessible from the state page in this session. In practice, New Hampshire’s math assessments are aligned to the state’s K-12 mathematics standards, which closely mirror Common Core grade-level domains and clusters.

A rectangular prism has length 22, width 44, and height 99. What is its volume?

V=2×4×9=72V = 2 \times 4 \times 9 = 72.

Two legs of a right triangle measure 66 and 88. What is the hypotenuse?

62+82=36+64=100=10\sqrt{6^2 + 8^2} = \sqrt{36 + 64} = \sqrt{100} = 10.

In XYZ\triangle XYZ, X\angle X and Z\angle Z are congruent. The measure of Y\angle Y is 52.652.6^{\circ}. What is the measure of X\angle X?

The two congruent angles share the remainder equally: 18052.62=63.7\dfrac{180^{\circ} - 52.6^{\circ}}{2} = 63.7^{\circ}.

What is the sum of the interior angles of a pentagon?

A pentagon has 55 sides: (52)×180=540°(5-2) \times 180 = 540°.

If a right triangle has a hypotenuse of 3030 yards and one leg of 1818 yards, what is the other leg?

Let the missing leg be xx. Then x2+182=302x^{2} + 18^{2} = 30^{2}, so x2=302182=900324=576x^{2} = 30^{2} - 18^{2} = 900 - 324 = 576 and x=576=24x = \sqrt{576} = 24.

A right triangle has legs 2020 and 2121. What is the hypotenuse?

202+212=400+441=84120^{2} + 21^{2} = 400 + 441 = 841, so the hypotenuse is 841=29.\sqrt{841} = 29\textsf{.}

Practice playeasy

Jordan walks 88 blocks east and then 1515 blocks north. How many blocks from the starting point is Jordan, measured in a straight line?

The walk forms the legs of a right triangle: 82+152=64+225=289=17\sqrt{8^{2} + 15^{2}} = \sqrt{64 + 225} = \sqrt{289} = 17 blocks.

A rectangle has length 88 centimeters and area 120120 square centimeters. What is the length of a diagonal of the rectangle, in centimeters?

Area A=wA = \ell w, so 120=8w120 = 8w and w=15w = 15. The diagonal is the hypotenuse of a right triangle with legs 88 and 1515: 82+152=64+225=289=17 cm.\sqrt{8^2 + 15^2} = \sqrt{64 + 225} = \sqrt{289} = 17\text{ cm}\textsf{.}
