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 Arizona’s Academic Standards Assessment (AASA) Grade 4 Mathematics exam — 175 items in all, written and reviewed by educators and aligned line-for-line to the Arizona Mathematics Standards (adopted December 2016, updated January 2025) and the 2025–2026 Essential Standards.
Take a look inside
Every test mirrors what your child will see on AASA test day: the 35-item on-screen load, two untimed parts on Pearson’s TestNav platform, the no-calculator rule, the no-reference-sheet rule, and the technology-enhanced item formats — multiple-choice, multi-select (“Select TWO”), equation-input keypad, and figure-based items (fraction models, line plots, area diagrams, hundredths grids, and geometric figures).
About the question count — and why field-test items matter: On the official AASA Grade 4 Math, some items count toward the score and some are unscored *field-test* items the state uses to develop future exams; students never know which is which. Each practice test here delivers the full 35-item on-screen length so your child builds the realistic test-day *endurance* the two-part untimed sitting demands.
What’s inside
- 5 complete 35-item practice tests (175 items total) — scored items plus embedded unmarked field-test items
- Two-part structure (Part 1: items 1–18; Part 2: items 19–35) — matching the real Math Unit 1 / Math Unit 2 format
- Step-by-step explanations for every question, teaching the *why* — not just the letter
- Difficulty steps up about 10 percent per test, from baseline Grade 4 work to capstone multistep reasoning by Test 5
- Essential Standards weighted heavily (4.OA.A.2/.A.3, 4.NBT.A.1/.B.5, 4.NF.A.1/.B.3/.C.6, 4.MD.A.3/.B.4) — matching Arizona’s 2025–2026 emphasis policy
- Parent letter with pacing guide, must-memorize conversions list, and test-taking tips
- A 175-item quick-reference answer key on its own page at the back

Why parents and teachers choose Smart Stars
- Written and reviewed by experienced educators — not generic test-prep authors
- Every question mirrors what students actually see on the AASA — we study the Arizona Department of Education’s Item Specifications, Performance Level Descriptors, and Sample Test Scoring Guide
- The deepest answer explanations in fourth-grade test prep — explanations teach reasoning, not just the letter
- Difficulty steps up about 10 percent per test, so every test feels fresh and progressively more demanding
- Field-test items built in (unmarked) for true test-day endurance from the first sitting
