About this book
Give your third grader the confidence to succeed on the Georgia Milestones Assessment System (GMAS) Mathematics test.
This book contains five full-length practice tests — 275 questions total — aligned to Georgia’s K–12 Mathematics Standards (2023 adoption) for Grade 3 and designed to match the format, difficulty, and content of the real GMAS Grade 3 Math exam. (This includes the embedded field-test items that appear on the actual GMAS exam, so each practice test mirrors the true 55-item count and helps your child build real-world test “endurance” for the full sitting.)
Take a look inside
On test day: a full Grade 3 GMAS Mathematics sitting runs about 60–75 minutes, and no calculator is allowed.
What’s inside
- 5 complete 55-item practice tests (275 questions total)
- Format that mirrors test day: a Reference Chart on its own page before every test, multiple-choice plus technology-enhanced item types (multi-select, multi-part Part A/Part B, and typed/keypad responses), and no calculator (matching the real Grade 3 test)
- Detailed answer explanations for every question — not just the correct letter, but step-by-step reasoning that builds real understanding
- Item types, names, and contexts varied across all 5 tests, so students never see the same problem twice in the same slot
- Reporting categories grouped exactly as on the official test: Numerical Reasoning, Patterning & Algebraic Reasoning, Measurement & Data Reasoning, and Geometric & Spatial Reasoning
- A parent letter with test-taking tips and a reference chart for length, liquid volume, mass, and time
- A quick-reference answer key for all five tests for fast scoring
Topics covered
- Place value through 10,000 — reading, writing, comparing, ordering, and rounding multi-digit whole numbers
- Rounding to the nearest 10, 100, and 1,000
- Multi-digit addition and subtraction within 10,000 with regrouping
- Two-step and multi-step word problems with whole numbers
- Estimation strategies and mental-math compensation
- Multiplication and division facts within 100
- Equal-groups, arrays, and missing-factor reasoning
- Two-step word problems with multiplication and division
- Fractions with denominators of 2, 3, 4, 6, and 8
- Identifying fractions on a number line and area model
- Equivalent fractions and same-denominator/same-numerator comparisons
- Whole numbers as fractions (3 = 3/1)
- Fraction of a set
- Length to the nearest quarter inch (with ruler tool)
- Liquid volume and mass in real-world problems
- Time to the nearest minute and elapsed time
- Reading bar graphs, picture graphs, and line plots
- Polygon classification: triangles, quadrilaterals, pentagons, hexagons, octagons
- Polygon attributes: parallel and perpendicular segments, right angles, lines of symmetry
- Quadrilateral hierarchy: rectangle, rhombus, square, trapezoid
- Area of rectangles by counting unit squares and by length × width
- Perimeter of rectangles, triangles, regular polygons, and irregular L-shapes
- Same-area-different-perimeter and same-perimeter-different-area reasoning
- Composite-figure area by decomposition
Why parents and teachers choose Smart Stars
- Written by experienced educators who study Georgia’s official GMAS specifications, ALDs, and DRC INSIGHT practice items
- Every question mirrors what students will see on test day — no surprises in format, content, or rigor
- Explanations teach the “why,” not just the “what,” so students learn from every mistake — every explanation includes a Strategy, a Tip, and a Connection that links the skill to the broader Grade 3 standards
- Item types and contexts varied across the five tests — just like a real exam, every question feels fresh
- 18 graphics per test on average — bar graphs, line plots, picture graphs, clocks, rulers, fraction models, polygons, and grids — so students practice with the visual question types they will see on the real GMAS
