Give your fourth grader the confidence to succeed on the Idaho ISAT Grade 4 Math test.
This Smart Stars practice book provides five full-length, Smarter-Balanced-aligned practice tests, each with 25 items that mirror the on-screen length and item mix of the real Idaho Standards Achievement Test (ISAT) in Mathematics. Every question was written by experienced educators, reviewed for accuracy, and built around the Idaho Content Standards for Mathematics at Grade 4 (the state’s Common Core-aligned standards).
Take a look inside
The ISAT Math test for Grade 4 is delivered online through Cambium Assessment in two untimed parts: a Computer Adaptive Test (CAT) portion followed by a Performance Task (PT) — a single real-world scenario that includes hand-scored short-response items. Idaho uses the shortened (“adjusted”) Smarter Balanced blueprint at Grade 4.
Each practice test here uses a 25-item structure — 19 CAT items plus a 6-item Performance Task — to mirror the true on-screen length (the scored items a student sees, plus the embedded field-test items the test quietly includes) and build real test-day endurance.
What’s inside
- Five full-length practice tests of 25 items each, with detailed Answers and Explanations after every test
- Coverage of every Grade 4 math standard across the three ISAT reporting categories: Concepts and Procedures; Problem Solving and Modeling & Data Analysis (Smarter Balanced Claims 2 and 4 combined for reporting); and Communicating Reasoning
- A unique Performance Task in every test, modeled on the real exam, with sample 2-point responses and scoring notes
- 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 a test-taking tips section to help families prepare
- No-calculator practice throughout, matching the official ISAT Grade 4 policy (Smarter Balanced math first allows an embedded calculator at Grade 6, not Grade 4)
Topics covered
- Place value to 1,000,000, and rounding to any place
- Multi-digit addition and subtraction, including regrouping across zeros
- Multi-digit multiplication (up to four digits by one digit, and two digits by two digits)
- Long division with remainders, and interpreting the remainder
- Multiplicative comparison (“times as many”), including multistep problems
- Factors and multiples, and prime versus composite numbers
- Number patterns, including two-step rules
- Equivalent fractions, and comparing and ordering fractions
- Adding and subtracting fractions and mixed numbers with like denominators
- Multiplying a fraction by a whole number
- Decimal notation for tenths and hundredths, comparing decimals, and adding tenths and hundredths
- Measurement and unit conversions (larger unit to smaller unit)
- Line plots in halves, quarters, and eighths of an inch
- Area and perimeter of rectangles, including unknown side lengths and composite figures
- Angles: measuring, classifying, and adding angles
- Lines of symmetry, and classifying triangles and quadrilaterals
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 ISAT structure, item mix, and policy (no calculator and no reference sheet at Grade 4).
- Varied across five tests: Slot positions, contexts, names, and number choices rotate test-to-test, and the tests step up in difficulty so no two feel like the same practice run.
- Field-test items built in: Each practice test includes unscored items that mirror the real field-test load on the live ISAT, building true test-day endurance.
