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 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 Illinois IAR 4th Grade Math Practice Test Workbook is aligned to the Illinois Learning Standards for Mathematics and built from the IAR blueprint published by the Illinois State Board of Education. 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.

What’s inside the IAR 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
17 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 41 skills.
Every big 4th grade idea
Multi-digit multiplication and division, place value, fractions, decimals, measurement, angles and lines.
Mixed review + strategies
41 mixed questions and four pages of test-taking tips for the big day.
2 full-length practice tests
31 questions each, split into Section 1, Section 2 and Section 3 like the real test.
Answer key + trackers
342 answers, rubrics for written answers, progress trackers, class data sheets and a certificate.
The question types match the real test: answer boxes, multiple choice, “select two” and “select three” questions, circle-the-choice questions, two-part Part A / Part B questions and written answers where students explain their thinking or model a real-world problem. Written answers are scored by hand on the IAR and carry a lot of points, so every one in the book comes with a rubric and a sample answer. Once 4th graders have met every format, test day is about the math, not the question style.

What’s on the IAR 4th grade math test?
The IAR (Illinois Assessment of Readiness) math test is taken on the computer in TestNav, with a paper form available. Fourth graders take it in three sections of 60 minutes each. The Illinois State Board of Education’s blueprint sets the grade 4 test at 31 scored questions worth 52 points, plus a few field-test questions that don’t count.
The points come from four areas: major content like multi-digit multiplication and division, fractions and decimals (the biggest share), additional and supporting content, expressing mathematical reasoning and modeling. The last two are written answers, where students explain their thinking or solve a real-world problem. Grades 3 to 5 take IAR math with no calculator, there’s no reference sheet in grade 4, and students get a ruler and a protractor on test day. Each practice test in the book has the same shape: 31 questions worth 52 points, split into three sections.
Every skill page is labeled with its Illinois Learning Standards code, so you can match it to your own scope and sequence.

2. Which is greater, 3/4 or 5/8?
3/4 — 3/4 = 6/8, and 6/8 is more than 5/8.
3. 2/5 + 1/5 = ?
3/5 — same denominator, so add the numerators.
