MSTAR Practice Worksheet

Lesson 8-3: Write and Solve Equations Using Multiplication or Division

Grade 6 Mathematics · Standard 6.AT.8

Name: Date:

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 A — Skills Check

Warm up with the lesson's core skills — one best answer each.

Question 1Selected response · 1 point

Solve: 6x = 42

Ax = 7
Bx = 36
Cx = 48
Dx = 252

Question 2Selected response · 1 point

Solve: n / 3 = 8

An = 3
Bn = 5
Cn = 11
Dn = 24

Question 3Selected response · 1 point

Solve: 9m = 63

Am = 7
Bm = 54
Cm = 72
Dm = 567

Question 4Selected response · 1 point

Solve: y / 7 = 5

Ay = 2
By = 7
Cy = 12
Dy = 35

Question 5Selected response · 1 point

A detective splits 54 clues equally among 9 case files. The equation 9c = 54 represents this. What is c?

Ac = 6
Bc = 9
Cc = 45
Dc = 63

Question 6Selected response · 1 point

Vault A is sealed with 4x = 32. Crack the lock: what is x?

Ax = 8
Bx = 28
Cx = 36
Dx = 128

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

What is the solution of 6m = 54?

Fill in the bubble next to the one best answer.

Am = 9
Bm = 48
Cm = 60
Dm = 324

Part B

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

Which reasoning justifies the step used to find that solution?

ADivision undoes multiplication, so dividing both sides by 6 isolates the variable.
BSubtracting 6 from both sides removes the 6 that is written next to the variable.
CMultiplying both sides by 6 isolates the variable because the same operation must be repeated.
DThe coefficient can simply be dropped because 6 is smaller than 54.

Question 8Select all that apply

Select ALL equations that have x = 8 as their solution.

Mark the box next to EVERY answer that is true. More than one is correct.

A4x = 32
Bx ÷ 2 = 4
C3x = 21
Dx ÷ 4 = 32
E56 = 7x

Part C — Show Your Thinking

Answer in writing, the way the state test's constructed responses work.

Question 9Written response · 2 points

A bakery packed muffins into boxes of 8. They made 96 muffins total. Write an equation, solve it, and explain why your answer is reasonable. Then write a different situation that uses division and has the same answer.

Write your answer in complete sentences. Show or explain your mathematical thinking.
