Standards basis

Minnesota Academic Standards in Mathematics (2007; assessed by MCA-III in grades 3-8 and 11 through 2026-27. 2022 standards phase in with MCA-IV beginning 2027-28) — Minnesota

How the MCA reports it

Minnesota’s MCA math is a state assessment tied to Minnesota Academic Standards in Mathematics rather than a separate national framework. The official public resources available here point to Minnesota-specific standards implementation, and absent a test blueprint, the coverage map should be organized by the state’s grade-level math domains that closely parallel CCSS-M. Note: the current MCA-III assesses the 2007 Minnesota standards in grades 3-8 and 11; Minnesota administers a single comprehensive high-school (grade 11) math test, NOT Algebra I / Geometry / Algebra II end-of-course exams — the 'High School / MCA EOC' band below is the grade-11 HS administration. (MCA-IV on the 2022 standards begins 2027-28.)

Similar triangles GHIGHI and JKLJKL have perimeters 1616 and 48.48\textsf{.} Side GHGH corresponds to side JK,JK\textsf{,} and GH=5.GH = 5\textsf{.} What is the length of JK?JK\textsf{?}

The scale factor from GHI\triangle GHI to JKL\triangle JKL is 4816=3.\dfrac{48}{16} = 3\textsf{.} Corresponding sides scale by 3,3\textsf{,} so JK=53=15.JK = 5 \cdot 3 = 15\textsf{.}

A school sold tickets to two events. What is the ratio of gala revenue to fair revenue in simplest form?
EventTickets availablePrice eachPercent soldGala100$4080%Fair200$1560%\begin{array}{l|c|c|c} \text{Event} & \text{Tickets available} & \text{Price each} & \text{Percent sold} \\ \hline \text{Gala} & 100 & \text{\char36}40 & 80\% \\ \text{Fair} & 200 & \text{\char36}15 & 60\% \end{array}

Gala tickets sold: 1000.80=80100 \cdot 0.80 = 80, so revenue is 8040=3,200.80 \cdot 40 = 3{,}200\textsf{.} Fair tickets sold: 2000.60=120200 \cdot 0.60 = 120, so revenue is 12015=1,800.120 \cdot 15 = 1{,}800\textsf{.} The ratio 3,200:1,8003{,}200:1{,}800 simplifies by dividing by 200200 to 16:9.16:9\textsf{.}

Iced tea is made with tea concentrate and water in a ratio of 33 to 1212. How many cups of tea concentrate should be added to 33 quarts of water to make the tea in this ratio? (44 cups == 11 quart, 44 quarts == 11 gallon.)

Three quarts of water is 3×4=123 \times 4 = 12 cups. With a 33 to 1212 ratio, 312=x12\dfrac{3}{12} = \dfrac{x}{12}, so x=3x = 3 cups of tea concentrate.

At an animal shelter, the ratio of cats to dogs is 55 to 88. If there are 3535 cats at the shelter, how many dogs are there?

Scale the ratio: 3535 cats is 77 groups of 55, so dogs = 7×8=567 \times 8 = 56.
