Give your third grader the confidence to succeed on the Arkansas ATLAS Grade 3 Math test.
This Smart Stars practice book provides five full-length, ATLAS-aligned practice tests, each with 40 items that mirror the operational length and item mix of the real ATLAS Mathematics assessment. Every test was written by experienced educators, reviewed for accuracy, and built around the Arkansas Mathematics Standards (2023) for Grade 3.
The ATLAS Mathematics test for Grade 3 students is computer-adaptive and contains roughly 35 scored operational items administered in one untimed session. This Smart Stars book gives each practice test the full 40-item structure (matching scored items plus a handful of unscored field-test-style items). (This includes the embedded unscored field-test items that appear on the actual ATLAS exam, so each practice test mirrors the true item count and helps your child build real-world test “endurance” for the full sitting.)
What’s inside
- Five full-length practice tests of 40 items each, with detailed Answers and Explanations after every test
- Coverage of every Grade 3 Arkansas Mathematics Standard across the three ATLAS reporting categories: Number & Place Value (38%); Computation & Algebraic Reasoning (31%); Geometry & Measurement / Data Analysis (31%)
- Every explanation includes a labeled Strategy and Tip so students learn the underlying reasoning, not just the answer
- A combined Quick Answer Key at the back of the book for fast self-grading
- A parent letter and test-taking tips section to set students up for success on test day
- No-calculator practice throughout, matching the official ATLAS Grade 3 policy
Topics covered
- Place value and rounding to ten and hundred for whole numbers up to 10,000
- Reading, writing, and comparing four-digit whole numbers
- Multiplication and division facts up to and including 12 by 12
- Two-step word problems using all four operations
- Multiplying one-digit numbers by multiples of 10
- Arithmetic patterns in addition and multiplication
- Equivalent fractions and fractions on the number line (including fractions greater than 1)
- Comparing fractions with the same numerator or the same denominator
- Decomposing fractions into sums of unit fractions
- Telling time to the nearest minute and solving elapsed-time problems
- Measuring lengths to the nearest half and quarter inch
- Liquid volume and mass in standard units (with one-step problems)
- Area as a count of unit squares and as length times width
- Identifying perpendicular and parallel lines, right angles, and quadrilateral categories (rhombus, rectangle, square, trapezoid)
- Reading and interpreting scaled picture graphs, scaled bar graphs, and line plots
Why parents and teachers choose Smart Stars
- Educator-authored. Every question is written and reviewed by classroom-experienced educators.
- Mirrors test day. Each practice test matches the official ATLAS structure, item count, and policy (no calculator, no reference sheet at Grade 3, ruler permitted for measurement items).
- Explanations teach the why. Every Answers and Explanations entry walks through the reasoning step by step, then provides a labeled Strategy and Tip so students learn the move, not just the answer.
- Varied across five tests. Slot positions, contexts, names, and number choices rotate test-to-test so no two tests feel like the same practice run.
- Field-test items built in. Each practice test includes unscored items that mirror ATLAS’s real field-test load, building true test-day endurance.
