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 Colorado CMAS 4th Grade Math Practice Test Workbook is aligned to the 2020 Colorado Academic Standards for Mathematics and built from the CMAS math framework published by the Colorado Department 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.
- A 17-question pretest, a Learn It lesson + test-style practice for all 41 skills, mixed review, test-taking strategies, 2 full-length practice tests and a 345-answer key.
- Each practice test has 33 questions worth 50 points in three units, just like the three units of the real CMAS math test.
- Printable PDF, 228 full-color pages, $9.99.
- A rubric and a sample full-credit answer for every written question, plus bubble answer sheets, progress trackers and class data sheets.

What’s inside the CMAS 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
33 questions each, split into Unit 1, Unit 2 and Unit 3 like the real test.
Answer key + trackers
345 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 all that apply” questions, check-mark tables, drop-down choices, two-part Part A / Part B questions and written answers where students explain their thinking. Written answers are scored by hand on the CMAS 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 CMAS 4th grade math test?
The CMAS (Colorado Measures of Academic Success) math test is taken on the computer, with a paper form available. It’s a fixed form, so every student sees the same questions and the test doesn’t adapt to answers. Fourth graders take it in three units of 65 minutes each, and the whole test is worth 50 to 51 points.
The points come from four areas: major content like multi-digit multiplication and division, fractions and decimals (the biggest share), supporting content, expressing mathematical reasoning and modeling and application. The last two are mostly written answers, where students explain their thinking or solve a real-world problem. Fourth graders get no calculator and no reference sheet, and when a question needs a protractor, it is printed right in the question. The Colorado Department of Education doesn’t publish the number of questions, so each practice test in the book has 33 questions worth 50 points, split into three units.
Every skill page is labeled with its 2020 Colorado Academic Standards code, so you can match it to your own scope and sequence.

CMAS 4th grade math test prep: questions teachers ask
Is this workbook made by the Colorado Department of Education?
No. Have Fun Teaching wrote every question from scratch, and a certified teacher reviewed the book. It is aligned to the 2020 Colorado Academic Standards for Mathematics and built from the published CMAS math framework, but it is an independent practice resource and does not use real test items.
How long is the CMAS 4th grade math test?
Fourth graders take the math test in three units of 65 minutes each, and the test is worth 50 to 51 points. The Colorado Department of Education doesn’t publish the number of questions, so each practice test in this workbook has 33 questions worth 50 points, split into Unit 1, Unit 2 and Unit 3.
How much does the workbook cost?
The Printable PDF is $9.99 for all 228 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 CMAS?
No. The grade 4 math test has no calculator, and reference sheets don’t start until grade 5. When a question needs a protractor, it is printed right in the question. The workbook practices the same way, so students get used to working problems out by hand.
When should I start CMAS 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 tentative 2026–27 testing window runs from April 5 to April 23, 2027.
Walk into test day ready.
Start with the pretest this week, and have every skill covered by spring.
