Give your fourth grader the confidence to succeed on the Alabama ACAP Summative Grade 4 Math test.
This Smart Stars practice book provides five full-length, ACAP-aligned practice tests, each with 50 items that mirror the operational length and item mix of the real assessment. Every test is built around the 2019 Alabama Course of Study: Mathematics for Grade 4.
The official ACAP Summative Grade 4 Math is administered on the computer in two untimed sessions of about 50 minutes each, with roughly 50 items per test day: 42 scored operational items plus unscored field-test items. This Smart Stars book gives each practice test the full 50-item structure (operational + about 5 unscored field-test-style items), so your student experiences the true test-day length and stamina.
Required for every test in this book: a pencil, scratch paper, and a physical protractor. Several items in every test ask the student to measure an angle from a printed protractor diagram. The live ACAP provides an on-screen protractor; this printed practice book needs a physical one. No calculator is allowed at Grade 4.
What’s inside
- Five full-length practice tests of 50 items each, with detailed Answers and Explanations after every test
- Coverage of every Grade 4 standard across the four ACAP reporting categories: Operations and Algebraic Thinking (19%); Operations with Numbers: Base Ten (19%); Operations with Numbers: Fractions (29%); Data Analysis, Measurement, and Geometry (33%)
- A one-page Reference Chart at the start of every test, mirroring the on-screen reference sheet provided during the live ACAP
- 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
Topics covered

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 ACAP structure, item count, and policy.
- Explanations teach the why. Every Answers and Explanations entry walks through the reasoning step by step.
- Varied across five tests. Slot positions, contexts, names, and numbers rotate so no two tests feel the same.
- Field-test items built in. Each test mirrors the real ACAP field-test load for true endurance.
