About this book
Built to feel like test day: Written to teach the why behind every answer.
This book gives your fourth grader five full-length practice tests for the Colorado Measures of Academic Success (CMAS) Grade 4 Mathematics exam — 300 items in all, written and reviewed by educators and aligned line-for-line to the Colorado Academic Standards for Mathematics.
Take a look inside
Every test in this book mirrors what your child will actually see on CMAS test day.
- Format: the same four-unit structure with clear STOP markers between units.
- Tools at Grade 4: the same no-calculator rule across the entire test, and no reference sheet (just like the real Grade 4 CMAS).
- Question types: the same item formats students encounter on Pearson’s TestNav platform — multiple-choice, multi-select (“select TWO” or “select ALL”), fill-in-the-blank equation-builder items with one or more typed blanks, ordering and comparison items, and multi-part constructed-response items where students explain and critique reasoning.
About the question count, and why field-test items matter.
- Length: on the official CMAS Grade 4 Math, roughly 32 items count toward your student’s score, worth about 50–51 points, because some constructed-response items earn 3, 4, or 6 points.
- Field-test items: the real test also includes embedded field-test items that the Colorado Department of Education (CDE) uses to develop future exams. Students never know which items count and which are field-test, so on test day every question must be worked with full focus and full energy.
- Each practice test here: the full operational scored load plus embedded unmarked field-test items — exactly mirroring the real on-screen experience — so your child builds the realistic endurance CMAS demands across four back-to-back units.
What’s inside
- 5 complete 60-item practice tests (300 items total) — operational scored items plus embedded unmarked field-test items, exactly like the live CMAS
- Four-unit structure with clear STOP markers between units — matching the real ~55-minute-per-unit CMAS Grade 4 Math format
- A printed Mathematics Reference Page before each test (time, length, mass, liquid volume, money conversions, and rectangle area/perimeter formulas) — placed on its own page so students learn to look there instead of inside the questions
- Two constructed-response items per test, including critique-the-flawed-student-reasoning items and multi-step modeling items with pictographs, bar graphs, and price tables — the dominant CR templates on the real CMAS Grade 4
- Step-by-step answer explanations for every question, teaching the *why* behind every correct answer — not just the letter
- Item types, names, contexts, and slot positions varied across all 5 tests, so no two tests feel the same and no student can game the layout
- A parent letter with the materials list (pencil, scratch paper, ruler, protractor), test-taking tips for Grade 4 CMAS Math, and a guide to pacing the five tests over several weeks
- A quick-reference answer key for the full 300-item book
Topics covered
- Place value through 1,000,000; reading, writing, and comparing six-digit numbers; rounding to any named place
- Multi-digit addition and subtraction with regrouping across zeros (the standard algorithm to fluency)
- Multi-digit multiplication up to 4-digit × 1-digit and 2-digit × 2-digit; multiplication-by-multiples-of-10 strategy
- Multi-digit division up to 4-digit ÷ 1-digit with remainders, including remainder-interpretation problems
- Multiplicative comparison: distinguishing “X times as many” from “X more than”; matching equations and word problems in both directions (find the larger amount; find the smaller amount)
- Multi-step word problems with all four operations, including problems that retain Grade 3 skills
- Factors, multiples, primes, composites, and factor pairs within 1–100
- Number and shape patterns from a rule (add, subtract, multiply); identifying features of a generated sequence
- Equivalent fractions and fraction comparison with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100
- Addition, subtraction, and multiplication of fractions; mixed-number addition and subtraction with and without regrouping; fraction × whole number expressed as a mixed number
- Decimal fractions in tenths and hundredths; converting between fractions and decimals; comparing and ordering decimals; plotting decimals on a number line
- Measurement conversion within a single system (km → m, m → cm, kg → g, L → mL, hr → min, ft → in, lb → oz); money problems
- Area and perimeter of rectangles, including finding a missing side from area and perimeter; multi-step area/perimeter problems
- Line plots with data in fractions of a unit (halves, quarters, eighths); reading frequency and total length/weight
- Angle measurement in whole-number degrees with a protractor; additive angle decomposition (two- and three-part)
- Classifying two-dimensional figures by parallel sides, perpendicular sides, equal-side relationships, and angle type; recognizing lines of symmetry
Why parents and teachers choose Smart Stars
- Written and reviewed by educators with deep classroom and university teaching experience — not generic test-prep authors
- Every question mirrors what students actually see on the CMAS: We study CDE’s released items, scoring guides, and the Colorado Academic Standards for every grade and subject we publish — so there are no surprises on test day
- The deepest answer explanations in fourth-grade test prep: Every explanation teaches reasoning, not just the letter — because students who understand *why* an answer is correct keep that skill long after the test
- Item types, contexts, and slot positions varied across the five tests, so every test feels fresh — exactly like the real exam
- Field-test items are built in (unmarked, exactly like the real CMAS), giving students true test-day endurance from the first practice session
