These are MSTAR-style questions written for this curriculum to rehearse the format. They are not official Maryland assessment items. MSTAR — Maryland's new state test, first given in spring 2027 — uses the same kinds of questions you see here: selected response, select-all, two-part evidence questions, and written responses.

Part B — Test-Format Questions

These match the state test's formats: two-part questions, select-all, and written responses.

Question 7Two-part question

Part A

A stadium shuttle carries fans from the parking lot. The table pairs the number of trips with the total fans carried: 2 trips with 96 fans, 5 trips with 240 fans, and 8 trips with 384 fans. On a graph with trips on the horizontal axis and fans on the vertical axis, which ordered pair belongs to 3 trips?

Fill in the bubble next to the one best answer.

A(3, 51)
B(3, 144)
C(3, 48)
D(144, 3)

Part B

Answer Part A before Part B — Part B asks about your reasoning.

Which explanation justifies the ordered pair chosen in Part A?

AThe larger number always comes first in an ordered pair, so the fans are written before the trips.
BThe shuttle carries 48 fans on each trip, and trips come first in the ordered pair, so 3 trips pair with 3 × 48 = 144 fans.
CThe rate of 48 fans is what gets plotted, so 3 trips pair with 48 fans.
DThe trips and the fans are added, so 3 trips pair with 48 + 3 = 51 fans.

Type II Reasoning: Reversed Coordinates

Ramona is graphing sales at the stadium pretzel stand. Pretzels cost $6 each, and her table shows 1 pretzel with $6, 2 pretzels with $12, and 3 pretzels with $18. She labels the horizontal axis 'number of pretzels' and the vertical axis 'total cost'. For 3 pretzels she plots the point (18, 3).

Explain Ramona's misconception and give the correct ordered pair for 3 pretzels.
