MSTAR Practice Worksheet

Lesson 3-3: Determine Equivalent Ratios Using Tables

Grade 6 Mathematics · Standard 6.AT.3a

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

A recipe uses 3 eggs for every 5 cups of flour. How many eggs are needed for 15 cups of flour?

Question 2Selected response · 1 point

Which row does NOT belong in a ratio table for 4:5?

A6:10
B8:10
C12:15
D16:20

Question 3Selected response · 1 point

A ratio table shows 3:7, 6:14, and 9:21. What is the next row?

A10:24
B12:28
C12:24
D15:28

Question 4Selected response · 1 point

A ratio table for 2:5 starts with 2:5, 4:10. What is the third row?

A5:10
B6:15
C6:12
D8:15

Question 5Selected response · 1 point

In a ratio table, the ratio of sugar to butter is 3:2. If you use 12 cups of sugar, how many cups of butter do you need?

Question 6Selected response · 1 point

A ratio table shows 5:8, 10:16, 15:24. What scale factor was used from the first row to the third row?

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 ratio table pairs 3 cups of flour with 2 cups of water. If the recipe is scaled to use 12 cups of flour, how much water is needed?

Fill in the bubble next to the one best answer.

A6 cups
B8 cups
C11 cups
D24 cups

Part B

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

Why is 11 cups an incorrect answer for Part A?

AIt divides instead of multiplying.
BIt uses the wrong conversion factor.
CIt adds 9 to both terms instead of multiplying both by the same factor.
DIt reverses flour and water.

Question 8Select all that apply

Select ALL statements that are true about ratio tables and equivalent ratios:

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

AMultiplying both terms of a ratio by 3 produces an equivalent ratio.
BDividing both terms by a common factor produces an equivalent ratio.
CAdding 5 to both terms produces an equivalent ratio.
DEvery row of a correct ratio table simplifies to the same ratio.
EA ratio table can be extended in either direction, up or down.

Part C — Show Your Thinking

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

Question 9Written response · 2 points

A recipe uses 4 cups of flour for every 3 cups of sugar. A student filled in a ratio table: 4:3, 8:6, 12:9, 14:12. Find and fix the error in the last row. Explain what went wrong.
