About this book
Give your fourth grader the confidence to succeed on the Iowa Grade 4 Math state test.
This Smart Stars practice book provides five full-length, standards-aligned practice tests that mirror the format and item mix of the Iowa Statewide Assessment of Student Progress (ISASP) Mathematics test. Every question was written by experienced educators, reviewed for accuracy, and built around the Iowa Academic Standards for Mathematics for Grade 4.
Take a look inside
The ISASP is given each spring to Iowa students in Grades 3-8, and again in high school, in English language arts, mathematics, and science.
- Delivery: authored by Iowa Testing Programs at the University of Iowa, delivered online by Pearson, and overseen by the Iowa Department of Education.
- Format: the Grade 4 Math test is computer-adaptive and item-based — it is scored on questions rather than on fixed units, so no two students see exactly the same form.
- Length: a student answers 50 questions in all — 44 that count toward the score, plus 6 embedded field-test questions the state is trying out for future tests, which look exactly like the scored ones but do not count.
- Tools at Grade 4: a four-function calculator is permitted on the real test.
- Each practice test here: 50 questions per test, 44 that count plus 6 field-test-style questions blended in and not marked, so your student practices the complete range of question types, math skills, and reporting domains they could meet on test day.
What’s inside
- Five full-length practice tests, with detailed Answers and Explanations after every test
- The real adaptive, item-based ISASP experience — 50 questions per test (44 scored plus 6 field-test-style), with no separate Performance Task, just like the real exam
- Coverage of every Grade 4 math standard across the five reporting domains the ISASP scores: Operations and Algebraic Thinking; Number and Operations in Base Ten; Number and Operations — Fractions; Measurement and Data; and Geometry
- Practice in every item format: multiple choice, multiple select, fill-in-the-blank and equation answers, drop-down and ordering questions, two-part questions, true/false tables, open-response “explain your thinking” questions, number lines, area models, line plots, angle and protractor figures, and figure-based questions
- Every explanation gives a full worked solution plus a labeled Strategy and a Tip, Check, or Estimate, so students learn the reasoning, not just the answer
- A graduated set of tests that step up in difficulty from Test 1 to Test 5, so students build steadily toward the hardest grade-level problems
- Real-world contexts throughout — Iowa farms and grain elevators, sports and recreation, science and nature, community life and shopping, and the arts, music, and travel
- A Grade 4 Math Study Reference Sheet to learn and review between tests (the state does not provide one on test day)
- A combined Quick Answer Key at the back of the book, with a worked answer for every one of the 50 questions on each test
- A family letter that explains the ISASP performance levels and where Grade 4 Proficient begins, so you can turn a practice score into an estimated level (Not Yet Proficient, Proficient, or Advanced)
- A test-taking tips section for students
Topics covered
- Place value to one million, and reading, writing, and comparing multi-digit whole numbers, including expanded form
- Rounding multi-digit whole numbers 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, using area models and partial products
- Division of up to four-digit numbers by one-digit numbers, with remainders interpreted in context
- Multiplicative comparison — “times as many” — and multi-step word problems that ask whether an answer is reasonable
- Factors and multiples, and prime and composite numbers
- Number and shape patterns and the rules behind them
- Equivalent fractions, and comparing and ordering fractions with unlike denominators
- Adding and subtracting fractions and mixed numbers with like denominators, and multiplying a fraction by a whole number
- Decimal notation for tenths and hundredths, and comparing decimals to the hundredths place
- The place-value relationship in which each place is ten times the place to its right
- Converting measurements within a system, from a larger unit to a smaller one
- Area and perimeter of rectangles, including finding a missing side
- Reading and interpreting line plots that use fractions of a unit
- Measuring and sketching angles, adding angle measures to find an unknown angle, and classifying angles as acute, right, obtuse, or straight
- Points, lines, rays, and parallel and perpendicular lines; classifying two-dimensional figures; and identifying lines of symmetry
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 ISASP format, computer-adaptive item-based structure, and item mix.
- Built for Iowa: Aligned to the Iowa Academic Standards for Mathematics, and organized around the same five reporting domains the ISASP scores.
- Explanations teach the why: Every Answers and Explanations entry gives a full worked solution, then a labeled Strategy and a Tip, Check, or Estimate, so students learn the move, not just the answer.
- Varied and graduated: Slot positions, contexts, names, and number choices rotate test-to-test, and the five tests step up in difficulty so no two feel like the same practice run.
