MSTAR Practice Worksheet

Lesson 4-1: Understand Percent

Grade 6 Mathematics · Standard 6.AT.4

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 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 robotics club had a fundraising goal of $500. By Friday, they collected $750. What percent of their goal did they achieve?

Fill in the bubble next to the one best answer.

A50%
B75%
C125%
D150%

Part B

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

Which explanation best supports your answer to Part A?

ASubtracting $500 from $750 gives $250, and 250 is 75% of 500.
BSince $500 is half of $1,000, the percent must be 50%.
CThe ratio 500 to 750 simplifies to 2 to 3, which is 125%.
DDividing $750 by $500 gives 1.5, and multiplying 1.5 by 100 gives 150%, representing 1.5 times the original whole.

Question 8Select all that apply

Select ALL statements that correctly represent a rate per 100 or compare percents to one whole:

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

A100% represents exactly one whole quantity.
B45 out of 100 squares shaded on a 10×10 grid represents 45%.
CA percent greater than 100% represents an amount that is more than the original whole.
D0.5% is equal to 50 out of 100.
EA percent is a ratio that compares a number to 100.

Part C — Show Your Thinking

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

Question 9Written response · 2 points

A car dealership sold 50 cars last month: 20 sedans, 15 SUVs, 10 trucks, and 5 vans. The owner will order 100 cars for next month and wants the order to match last month's sales pattern. Write each type as a percent, then say how many of each to order — and explain why percents make this easier than the raw counts.
