North Dakota ND A+ Grade 3 Math Practice Tests

Give your third grader the confidence to succeed on the North Dakota ND A+ 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 ND A+ spring assessment in Mathematics. Every question was written by experienced educators, reviewed for accuracy, and built around the 2023 North Dakota Mathematics Content Standards at Grade 3 — the standards North Dakota adopted for its own classrooms — so the topics and emphasis match what North Dakota students actually see.

Take a look inside

ND A+ — the North Dakota Academic Progression of Learning and Understanding of Students — is the statewide test the North Dakota Department of Public Instruction gives to every public-school student in Grades 3-8.

• Delivery: delivered online by Pearson and, at Grade 3, taken in a single session as a fixed form, with a spring administration that counts toward grade-level results.
• Tools at Grade 3: NO calculator — every question is meant to be worked by hand — and no reference sheet.
• Question types: every question is machine-scored — single-answer multiple choice, multiple-select (“select two”), and typed-in numeric answers.
• Length: a student answers about 38 scored questions plus a few unscored field-test questions blended in invisibly.
• Each practice test here: 38 scored-style questions plus 6 field-test-style questions, 44 in all, for 220 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
• The single-session, no-calculator structure of the real test, so practice feels like test day
• Coverage of every Grade 3 math reporting category North Dakota uses — Number and Operations, Algebraic Reasoning, Geometry and Measurement, and Data, Probability, and Statistics — weighted toward the Number and Operations work that carries the most questions, just like the real blueprint
• Field-test-style questions blended invisibly into each test, just like the real ND A+, and fully answered here so nothing on test day feels unfamiliar
• Practice in the exact ND A+ item formats: single-answer multiple choice, multiple-select (“select two”), and typed-in numeric answers, plus number lines, line plots, area models, clocks, coins, scaled bar and picture graphs, and figure-based geometry
• A combined Quick Answer Key after each test for fast self-grading
• A family letter, a test-taking tips section, and a Grade 3 math study reference page up front — included as a study aid, since the real ND A+ provides no reference sheet at Grade 3
• A no-calculator approach matched to the real policy — the Grade 3 test allows no calculator, so every question here is built to be solved by hand

Topics covered

• Place value, and reading, writing, comparing, and rounding whole numbers — including North Dakota’s Grade 3 reach to 10,000, with numbers in standard, word, and expanded form and four-digit comparisons
• Adding and subtracting whole numbers within 1,000, with and without regrouping
• Understanding multiplication and division through arrays, equal groups, area, and the way multiplication and division undo each other, with fluency within 100
• Multiplying one-digit numbers by multiples of ten
• Two-step word problems, properties of operations, and number patterns
• Fractions as numbers: unit fractions, fractions on a number line, equivalent fractions, whole numbers written as fractions, and comparing fractions with the same numerator or the same denominator (halves, thirds, fourths, sixths, and eighths)
• Sorting and classifying quadrilaterals by their sides and angles
• Angle types — right, acute, and obtuse — and lines of symmetry, part of North Dakota’s Grade 3 geometry
• Perimeter of rectangles, including finding an unknown side length
• Area of a rectangle by tiling with unit squares and by multiplying side lengths
• Telling and writing time to the minute, and finding elapsed time
• Money: solving problems with coins and the cent symbol
• Measuring and estimating mass and liquid volume in grams, kilograms, and liters
• Reading and building scaled picture graphs and bar graphs, and line plots marked in halves and quarters of an inch
• Analyzing data to answer “how many more,” combine-and-compare, and two-step questions

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 ND A+ shape, item mix, question formats, single-session no-calculator policy, and no-reference-sheet rule, with field-test questions blended in invisibly just like the real test.
• Built for North Dakota: Aligned to the 2023 North Dakota Mathematics Content Standards at Grade 3 — including North Dakota’s own Grade 3 emphases such as numbers to 10,000, four-digit comparison, angle types, and lines of symmetry — with grade-appropriate real-world contexts and a friendly cast of student characters.
• 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 — the later tests lean on more multi-step and multi-select reasoning — so no two feel like the same practice run.
