Give your third grader the confidence to succeed on the New Jersey NJSLA Grade 3 Math test.
This Smart Stars practice book provides five full-length, standards-aligned practice tests that mirror the length, item mix, and question types of the real NJSLA spring assessment in Mathematics. Every question was written by experienced educators, reviewed for accuracy, and built around the 2023 New Jersey Student Learning Standards for Mathematics at Grade 3 (the Common Core domains New Jersey uses) so the topics and emphasis match what New Jersey students actually see.
NJSLA (the New Jersey Student Learning Assessments) is the test the New Jersey Department of Education gives to every public-school student in Grades 3-8. On the test a student answers 41 scored questions, with a few unscored field-test questions mixed in invisibly. Each practice test here follows that same shape: 41 scored-style questions plus 4 field-test-style questions, 45 in all, for 225 questions across the book: to build true test-day endurance.
What’s inside
- Five full-length practice tests, with detailed Answers and Explanations after every test
- Coverage of every Grade 3 math reporting category New Jersey uses (Operations and Algebraic Thinking; Number and Operations in Base Ten and Fractions; Measurement; and Geometry and Data Literacy) weighted just like the real blueprint
- Field-test-style questions blended invisibly into each test, just like the real NJSLA, and fully answered here so nothing on test day feels unfamiliar
- 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 wide, easy-to-scan Quick Answer Key after the tests for fast self-grading
Topics covered
- Place value, and reading, writing, comparing, and rounding whole numbers to the nearest ten and hundred, including standard and expanded form
- Adding and subtracting whole numbers within 1,000, with and without regrouping, and missing-number problems
- Understanding multiplication and division through arrays, equal groups, repeated addition, and number lines, and the way multiplication and division undo each other
- Multiplication and division facts within 100, unknown-factor problems, the properties of operations, and multiplying one-digit numbers by multiples of ten
- “Times as many” multiplicative comparison, two-step word problems, and arithmetic patterns
- Fractions as numbers: unit fractions, fractions of a whole, fractions on a number line, equivalent fractions, whole numbers written as fractions, and comparing and ordering fractions with the same numerator or the same denominator (halves, thirds, fourths, sixths, and eighths)
- Sorting and classifying quadrilaterals (squares, rectangles, rhombuses, and trapezoids) and partitioning shapes into equal parts
- Perimeter of polygons, including finding an unknown side and composite (L-shaped) figures
- Telling and writing time to the minute, and finding elapsed time, plus mass and liquid volume
- Reading and building scaled picture graphs and bar graphs, and line plots
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 shape, machine-scored item mix, question formats, and no-calculator, no-reference-sheet policy, with field-test questions blended in invisibly just like the real 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.
