Give your fourth grader the confidence to succeed on the New Jersey NJSLA Grade 4 Math test.
This Smart Stars practice book provides five full-length, standards-aligned practice tests that mirror the length, item mix, and on-screen experience of the real New Jersey Student Learning Assessment (NJSLA) in Mathematics at Grade 4. Every question was written by experienced educators, reviewed for accuracy, and built around the New Jersey Student Learning Standards for Mathematics at Grade 4.
The NJSLA is given to New Jersey public-school students each spring in Grades 3-8. It is a program of the New Jersey Department of Education (NJDOE), and the current NJSLA-Adaptive (NJSLA-A) mathematics test is delivered by Cambium Assessment, Inc. (CAI). Grade 4 math is given in two sessions and taken without a calculator (calculators are not allowed in Grades 3-5; an on-screen ruler and protractor are provided when needed: Grade 4 is the first grade that measures angles with a protractor). The adaptive test uses only machine-scorable question types: there are no long written-response questions at Grade 4: and it quietly includes a few unscored “field-test” questions that look exactly like the rest. Each practice test here follows the same shape: 45 questions per test: 41 that count plus 4 unmarked field-test-style questions: for 225 questions in all, to build true test-day endurance.
What’s inside
- Five full-length practice tests, each given in two no-calculator sessions, with detailed Answers and Explanations immediately after every test
- Coverage of every Grade 4 math reporting area: Number & Operations in Base Ten, Number & Operations-Fractions, Operations & Algebraic Thinking with Measurement, and Geometry with Data Literacy: weighted to match the NJSLA test blueprint, where fractions form the largest single content strand
- Practice in every NJSLA-Adaptive item format: multiple choice, multiple select (“select all that apply”), type-in (fill-in-the-box) numeric and fraction answers, fill-in-the-table, and create-a-fraction items: with the online drag-and-drop, drop-down, grid, and hot-spot items rendered as clear print equivalents
- Field-test-style questions blended invisibly and unmarked into each test, exactly as the NJSLA embeds its own unscored field-test questions, and fully answered here so nothing on test day feels unfamiliar
- Figure-based questions: protractor angle reads, line plots, area and perimeter figures, fraction and decimal models, and shape-classification diagrams: all in clean black-and-white print
- Every explanation walks through the reasoning step by step and ends with a labeled Tip, Check, or Estimate (with a Strategy on the multi-step questions), so students learn the move, not just the answer
- A combined Quick Answer Key at the back of the book for fast self-grading
- A family letter, a test-taking tips section, and a Grade 4 Math reference sheet (the conversions and area/perimeter formulas students should know on test day) up front
How the NJSLA is scored:
Topics covered
- Place value to the hundred-thousands: reading, writing, comparing, and rounding multi-digit whole numbers, and understanding that a digit represents ten times the place to its right
- Multi-digit addition and subtraction, multiplying up to a four-digit number by a one-digit number and two two-digit numbers, and dividing by a one-digit number with remainders, all in real-world word problems
- Fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100: equivalent fractions, comparing and ordering, adding and subtracting fractions and mixed numbers with like denominators, and multiplying a fraction by a whole number
- Decimals to hundredths: decimal notation for fractions with denominators 10 and 100, and comparing decimals
- Factors and multiples, prime and composite numbers, multiplicative comparison, multi-step word problems, and generating and analyzing number patterns
- Geometry: points, lines, rays, angles, perpendicular and parallel lines, classifying two-dimensional shapes, and lines of symmetry
- Measuring angles in whole-number degrees with a protractor, converting measurements from a larger unit to a smaller unit, and finding area and perimeter
- Reading and analyzing data on line plots in fractions of a unit (halves, fourths, and eighths)
- New Jersey reports each student in one of five performance levels (Did Not Yet Meet Expectations, Partially Met Expectations, Approached Expectations, Met Expectations, or Exceeded Expectations) and a student who reaches Met Expectations or above meets the grade-level standard, while Exceeded Expectations shows above-grade mastery
- Mathematics is reported on a scale score that spans Grades 3-8, ranging from 650 to 850, with the Met Expectations (proficiency) cut set at 750
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 NJSLA-Adaptive item mix, two-session no-calculator design, machine-scorable-only structure, and the unmarked field-test questions on the real test.
- Built for New Jersey. Aligned to the New Jersey Student Learning Standards in Mathematics and the NJSLA test blueprint, weighted toward fractions just like the real Grade 4 test.
- Explanations teach the why. Every Answers and Explanations entry shows the full worked solution, then a labeled closing Tip, Check, or Estimate (and a Strategy on multi-step problems) so students learn the reasoning.
- 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.
