Sample OSAS Math Grade 4 Practice Questions

Try these sample questions to review concepts for the OSAS Math Grade 4 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In the number 384,752, what is the value of the digit 8?
A.8,000
B.80,000
C.800
D.8
Explanation: The digit 8 is in the ten-thousands place. Its value is 8 × 10,000 = 80,000.
2Which expression shows 506,219 in expanded form?
A.500,000 + 60,000 + 2,000 + 100 + 9
B.500,000 + 60,000 + 200 + 10 + 9
C.500,000 + 6,000 + 200 + 10 + 9
D.50,000 + 6,000 + 200 + 10 + 9
Explanation: Read each digit by its place: 5 is hundred-thousands (500,000), 0 is ten-thousands, 6 is thousands (6,000), 2 is hundreds (200), 1 is tens (10), and 9 is ones (9). Adding only the nonzero place values gives 500,000 + 6,000 + 200 + 10 + 9 = 506,219.
3Which symbol makes the statement true? 247,805 ___ 247,850
A.>
B.<
C.=
D.≥
Explanation: Both numbers share 247,8 in the first four places. The tens digit differs: 0 vs 5, so 247,805 < 247,850.
4Round 18,467 to the nearest thousand.
A.18,000
B.18,500
C.19,000
D.20,000
Explanation: The thousands digit is 8, and the digit immediately to its right (the hundreds digit) is 4. Because 4 is less than 5, the thousands digit stays 8 and every digit to the right becomes zero: 18,467 rounds to 18,000. Distance confirms it — 18,467 is 467 from 18,000 but 533 from 19,000.
5Round 732,914 to the nearest ten-thousand.
A.730,000
B.732,000
C.735,000
D.740,000
Explanation: The ten-thousands digit is 3, and the digit to its right (thousands) is 2. Since 2 < 5, we keep 3: 732,914 rounds to 730,000.
6Calculate 15,847 + 23,916.
A.38,763
B.39,763
C.38,663
D.39,663
Explanation: Add column by column: 7+6=13 (write 3, carry 1); 4+1+1=6; 8+9=17 (write 7, carry 1); 5+3+1=9; 1+2=3. The sum is 39,763.
7Calculate 60,000 − 24,583.
A.35,417
B.36,417
C.35,483
D.34,417
Explanation: Regroup across zeros: 60,000 − 24,583 = 35,417. Check: 35,417 + 24,583 = 60,000.
8Calculate 3,748 × 6.
A.22,488
B.22,484
C.21,488
D.22,448
Explanation: 3,748 × 6: 8×6=48 (write 8, carry 4); 4×6+4=28 (write 8, carry 2); 7×6+2=44 (write 4, carry 4); 3×6+4=22. The product is 22,488.
9Calculate 47 × 36.
A.1,692
B.1,482
C.1,782
D.1,682
Explanation: 47 × 36 = 47 × 30 + 47 × 6 = 1,410 + 282 = 1,692.
10Calculate 5,837 ÷ 7. What are the quotient and remainder?
A.Quotient 833, remainder 6
B.Quotient 834, remainder 5
C.Quotient 833, remainder 0
D.Quotient 835, remainder 2
Explanation: 5,837 ÷ 7: 58÷7=8 r2; bring down 3 → 23÷7=3 r2; bring down 7 → 27÷7=3 r6. Quotient = 833, remainder = 6. Check: 833×7+6 = 5,831+6 = 5,837.

About the OSAS Math Grade 4 Exam

The OSAS Grade 4 Mathematics assessment measures student proficiency against the 2021 Oregon Mathematics Standards. It is reported in three categories — Concepts and Procedures, Problem Solving and Modeling/Data Analysis, and Communicating Reasoning — through a Smarter Balanced computer-adaptive test and a Performance Task.

Exam sponsor: Oregon Department of Education (ODE); Mathematics assessment delivered as part of the Smarter Balanced Assessment Consortium. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Online Smarter Balanced assessment with two components: a Computer Adaptive Test (CAT) of selected-response, technology-enhanced and equation-entry items, and a Performance Task (PT) of multi-step problem-solving items. Reporting categories are Concepts and Procedures (Claim 1: 10 of the 17 operational CAT items), Problem Solving and Modeling/Data Analysis (Claims 2 and 4 combined: 3 CAT items plus most of the 4-6 Performance Task items), and Communicating Reasoning (Claim 3: 4 CAT items plus 0-2 Performance Task items). Aligned to the 2021 Oregon Mathematics Standards.

Time Limit

Untimed; most students complete the CAT and Performance Task in under two hours

Passing Score

No pass/fail mark. Results are reported on four achievement levels (Levels 1-4); Levels 3 and 4 are considered proficient.

Exam / Certification Fees

No fee to students

OSAS Math Grade 4: Suggested Study Strategy

1Build fluency with the priority grade-level computation and concept targets, which anchor the Concepts and Procedures claim (10 of the 17 operational CAT items).
2Practise multi-step word problems in real-world contexts — Problem Solving and Modeling/Data Analysis carries 3 CAT items plus most of the Performance Task.
3Work on explaining your reasoning in words, equations, and diagrams; the Communicating Reasoning claim asks you to construct and critique arguments.
4Use diagrams, tables, and graphs to model situations and interpret results in context.
5Try the free OSAS sample and training tests on the OSAS Portal, including the Spanish/English toggle, so the online tools are familiar.
