Fourth grade math is a big step up. Students multiply and divide bigger numbers, compare and add fractions, write decimals as tenths and hundredths, convert metric measurements and measure angles with a protractor. All of it shows up on one spring test. If you want every skill covered in one place, this workbook was made for you.
The Ohio OST 4th Grade Math Practice Test Workbook is aligned to Ohio’s Learning Standards for Mathematics and built from the grade 4 math blueprint and test specifications for Ohio’s State Tests, published by the Ohio Department of Education and Workforce. Every question is original, written in the formats your students will see in the spring, and reviewed by a certified teacher.
It’s a Printable PDF, so you can print the pages you need for whole-class lessons, small groups, centers or homework. Below you’ll find what’s inside, a look-inside video and a simple plan for the months before testing.
- A 20-question pretest, a Learn It lesson + test-style practice for all 34 skills, mixed review, test-taking strategies, 2 full-length practice tests and a 336-answer key.
- Each practice test has 46 questions worth 49 points in two parts, just like the two parts of the real OST math test.
- Printable PDF, 200 full-color pages, $9.99.
- Bubble answer sheets, progress trackers and class data sheets make scoring quick.

What’s inside the OST 4th grade math test prep workbook
The workbook follows the order you’d teach it. Find out what students already know, teach the gaps one skill at a time, mix everything together, then rehearse the real thing twice.
Pretest + scoring guide
20 questions and a guide that shows which skills to teach first.
Learn It + practice
A worked example and a tip, then test-style practice, for all 34 skills.
Every big 4th grade idea
Multi-digit multiplication and division, place value, fractions, decimals, measurement, angles and lines.
Mixed review + strategies
34 mixed questions and four pages of test-taking tips for the big day.
2 full-length practice tests
46 questions each, split into Part 1 and Part 2 like the real test.
Answer key + trackers
336 answers, progress trackers, class data sheets and a certificate.
The question types match the real test: answer boxes, tables to complete, multiple choice, “select two or three” questions, check-box tables, circle-the-choice questions and two-part Part A / Part B questions. On the computer, some questions have students drag numbers, draw or click; in the book, students write those answers in boxes, fill in bubbles or circle a choice. Once 4th graders have met every format, test day is about the math, not the question style.

What’s on the OST 4th grade math test?
Ohio’s State Tests (OST) in math are taken on the computer, and paper tests are an accommodation. It’s a fixed form, so the test doesn’t adapt to answers. Fourth graders take it in two parts of 75 minutes each, on one day or on two days, and the whole test is worth about 49 points. Every math question is scored by computer, and Part A / Part B questions can earn partial credit.
The points come from three reporting categories: Multiplication and Division (the biggest share), Fractions, and Geometry. Ohio also reports Modeling and Reasoning, at least 20% of the points, from word problems and multi-step questions in every category. Fourth graders get no calculator, but they can open a grade 4 reference sheet with metric conversions and 1 hour = 60 minutes. The workbook prints its own copy in the front, and every angle-measuring question shows the protractor right on the figure. The Ohio Department of Education and Workforce doesn’t publish the number of questions, so each practice test in the book has 46 questions worth 49 points, split into two parts.
Every skill page is labeled with its Ohio’s Learning Standards code (4.OA.1, 4.NF.3a and so on), so you can match it to your own scope and sequence.

36 inches — 1 foot = 12 inches, and 3 × 12 = 36.
3. 4 × 2/3 = ?
8/3, or 2 2/3 — 4 groups of 2/3 is 8 thirds.

OST 4th grade math test prep: questions teachers ask
Is this workbook made by the Ohio Department of Education and Workforce?
No. Have Fun Teaching wrote every question from scratch, and a certified teacher reviewed the book. It is aligned to Ohio’s Learning Standards for Mathematics and built from the published OST grade 4 math blueprint and test specifications, but it is an independent practice resource and does not use real test items.
How long is the OST 4th grade math test?
Fourth graders take the math test in two parts of 75 minutes each, on one day or on two days, and the test is worth about 49 points. The Ohio Department of Education and Workforce doesn’t publish the number of questions, so each practice test in this workbook has 46 questions worth 49 points, split into Part 1 and Part 2.
How much does the workbook cost?
The Printable PDF is $9.99 for all 200 full-color pages, and you can print as many copies as your students need. With a Have Fun Teaching membership, the PDF is included at no extra cost, along with the Printable PDF of every other state test prep workbook and the rest of the library.
Can 4th graders use a calculator or a reference sheet on the OST?
There is no calculator: grades 3 to 5 take the whole math test without one. There is a reference sheet: on test day, 4th graders can open a grade 4 sheet with metric conversions and 1 hour = 60 minutes. The workbook prints its own copy in the front, so students practice with it all year.
When should I start OST 4th grade math test prep?
Start with the pretest in the fall, then teach the skills it flags a few times a week through winter. Give Practice Test 1 in early spring and Practice Test 2 a few weeks later. The 2026–27 spring testing window runs from April 5 to May 14, 2027, and each district picks 15 consecutive school days inside it.
Walk into test day ready.
Start with the pretest this week, and have every skill covered by spring.
