NJSLA Grade 3 Math Practice Test: What New Jersey Students Should Review

New Jersey Grade 3 students preparing for NJSLA math should review multiplication, division, place value, fractions, measurement, data, area, perimeter, and multi-step word problems. A good practice test does more than predict a score. It shows which skills are automatic, which skills need reteaching, and whether the student can explain a solution clearly enough to avoid careless test-day mistakes.

For official details, start with the NJSLA Mathematics Companion Guide and the New Jersey Assessments Portal practice tests. The companion guide describes NJSLA-M as measuring grade-level skills, concepts, reasoning, and modeling, with a mix of objective and constructed-response item types. Grade 3 families should use official pages for current schedules, platform information, and state policy, then use independent practice materials for day-to-day skill building.

Quick Diagnostic Before the Practice Test

Before giving a full mixed set, ask the student to complete one problem from each major Grade 3 area. If they miss two or more, pause and review those skills first. This prevents the practice test from becoming a long guessing session.

• Fact fluency: Can the student solve 6 x 7 and explain it with equal groups?
• Place value: Can the student round 467 to the nearest ten and nearest hundred?
• Fractions: Can the student show 3/4 on a number line from 0 to 1?
• Measurement: Can the student find elapsed time from 1:20 to 2:05?
• Geometry: Can the student explain the difference between area and perimeter?

What Grade 3 Students Should Review

• Operations and algebraic thinking: multiplication, division, arrays, equal groups, unknown-number equations, and two-step word problems.
• Base ten: rounding, adding and subtracting within 1,000, and multiplying one-digit numbers by multiples of 10.
• Fractions: unit fractions, fractions on a number line, equivalent fractions, and comparing fractions with the same numerator or denominator.
• Measurement and data: time, elapsed time, mass, volume, picture graphs, bar graphs, and line plots.
• Geometry: area, perimeter, quadrilaterals, and partitioning shapes into equal parts.

Mini NJSLA Grade 3 Math Practice Test

These are original ViewMath practice questions, not released NJSLA items. Have the student show work for every word problem.

1. What is 7 x 8?
2. Write a division equation for: 24 objects are split equally into 6 groups.
3. Round 467 to the nearest hundred.
4. Add: 348 + 275.
5. Subtract: 702 – 458.
6. Which fraction is greater: 3/6 or 3/8?
7. What fraction of a rectangle is shaded if 5 of 8 equal parts are shaded?
8. A movie starts at 2:15 and ends at 3:05. How long is the movie?
9. A box has 4 rows of 6 pencils. How many pencils are in the box?
10. A garden is 9 feet long and 5 feet wide. What is its area?
11. A rectangle has side lengths 8 cm and 3 cm. What is its perimeter?
12. A bar graph shows 12 students chose soccer, 9 chose basketball, and 6 chose tennis. How many more students chose soccer than tennis?

19. A square has side length 6 inches. What are its area and perimeter?
20. Which number makes this equation true: ___ + 238 = 600?

Answer Key with Worked Notes

1. 56.
2. 24 / 6 = 4.
3. 500, because 467 is closer to 500 than to 400.
4. 623.
5. 244.
6. 3/6 is greater because sixths are larger than eighths when the numerator is the same.
7. 5/8.
8. 50 minutes. From 2:15 to 3:00 is 45 minutes, plus 5 minutes.
9. 24 pencils.
10. 45 square feet. Area = 9 x 5.
11. 22 cm. Perimeter = 8 + 3 + 8 + 3.
12. 6 more students.
13. 7.
14. 9 stickers.
15. 529.
16. 7 inches. 18 – 7 – 4 = 7.
17. 17 students. 5 x 4 = 20 seats; 20 – 3 = 17.
18. 48 pages. 14 + 18 + 16 = 48.
19. Area = 36 square inches; perimeter = 24 inches.
20. 362, because 600 – 238 = 362.

Common Mistakes to Fix Early

• Area and perimeter mix-ups: Ask, “Am I covering the inside or walking around the outside?” before choosing a formula.
• Fraction size confusion: Draw the same-size whole before comparing denominators. Bigger denominators mean smaller equal pieces.
• Operation guessing: Require a number sentence for word problems. Students should not jump from reading directly to calculating.
• Elapsed-time counting errors: Count to the next hour first, then add remaining minutes.
• Rounding without place value: Circle the place being rounded and underline the digit to the right.
