Unit 7 MSTAR-Style Practice Test — Form B

Integers, Rational Numbers, and the Coordinate Plane · 9 questions · English only, like the real test · No timer — take the time you need.

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.

How this works: Answer every question, then press Submit & Grade. Selected-response parts grade instantly with an explanation for each; written responses go to your teacher. Your answers save on this device.

On the real MSTAR: math runs as three 40-minute sessions, in English, on a computer. Here there is no clock — practice the thinking first; the pacing comes with rehearsal.

Written responses: how should the explain-the-error questions be scored?

Instant scoring checks whether your explanation states the value and uses the reasoning the question is about. It matches words and numbers, so a right answer worded differently can score low — your teacher can always re-score it from the answer key.

16.NOS.6Explore Integers and Their Opposites

Part A

Badwater Basin sits 86 meters below sea level, where sea level is defined as 0. Which integer represents this elevation?

0 −8.6 −86 86

Part B

What is the opposite of −86, and what does it represent here?

0, sea level itself 1/86, a fraction of the depth 86, an elevation 86 meters ABOVE sea level −86, the same elevation

26.NOS.6Represent Rational Numbers and Their Opposites on the Number Line

Part A

Between which two consecutive integers does −3.5 fall on a number line?

−3 and −2 3 and 4 −4 and −3 −5 and −4

Part B

A student says −3.5 is greater than −3 because 3.5 is greater than 3. Why is this reasoning wrong?

3.5 is not actually greater than 3. On a number line, the further left a number is, the smaller it is, and −3.5 is left of −3. Negative numbers cannot be compared. Decimals are always smaller than integers.

36.NOS.8Understand Absolute Value of Rational Numbers

Explain the error

Owen compared −8 and −3. He wrote: 'Since |−8| = 8 and |−3| = 3, and 8 > 3, then −8 > −3.'

Explain Owen's misconception and state the correct comparison.

46.NOS.8Compare and Order Integers and Rational Numbers

Select all that apply

Select ALL comparisons that are TRUE:

−7 < −2 0 > −1 −0.5 > −1.5 −10 > −3 2.5 > −9

56.NOS.6Represent Rational Numbers on the Coordinate Plane

Part A

Starting at the origin, which point is located by moving 4 units LEFT and 3 units UP?

(3, −4) (−3, 4) (−4, 3) (4, 3)

Part B

Why do (−4, 3) and (3, −4) name different points?

They are actually the same point drawn twice. The order matters: the first number is always the horizontal move, the second the vertical. Negative coordinates cannot come first. The larger number is always written first.

66.NOS.9Determine Distance on the Coordinate Plane

Part A

A chest sits at (−3, 2) and a cave at (4, 2). How far apart are they?

1 unit 2 units 5 units 7 units

Part B

Why can this distance be found by subtraction alone?

The two points share the same y-coordinate, so the segment between them is horizontal. Subtraction works for any two points on the plane. Both coordinates are whole numbers. One of the points is in Quadrant II.

76.NOS.9Represent Polygons on the Coordinate Plane

Select all that apply

Select ALL statements that are true about polygons on the coordinate plane:

Vertices are connected in the order given to form the polygon. A horizontal side's length is the absolute difference of the x-coordinates. A vertical side's length is the absolute difference of the y-coordinates. The length of a slanted side can be found by subtracting coordinates. The area of a rectangle on the grid is the product of its side lengths.

86.NOS.7Ordered Pairs in All Four Quadrants

Part A

In which quadrant does the point (−4, 3) lie?

Quadrant II Quadrant I Quadrant III Quadrant IV

Part B

What sign pattern identifies Quadrant IV?

(−, −) (−, +) (+, −) (+, +)

96.NOS.7Reflect Points Across Axes

Explain the error

Dante reflected (3, 7) across the y-axis. He wrote: 'Change the sign of y, so the image is (3, −7).'

Explain Dante's misconception and give the correct image point.
