Every parent of a fourth grader notices it eventually: the math homework takes longer than it used to. That is not a problem — it is the year working as designed. Fourth grade is when numbers grow into the hundred-thousands and have to be read, rounded, and compared with ease. Multiplication becomes a multi-step procedure instead of a single fact. Division begins to leave remainders, and a remainder is something a child has to think about and explain, not just jot down. The questions are longer because the thinking inside them has grown.
Fractions become real numbers this year, not just shaded shapes — equivalence, comparison, adding and subtracting with like denominators, mixed numbers, and multiplying a fraction by a whole number. Decimals to the hundredths show up for the first time. So do angles, area and perimeter, line plots, and multi-step word problems that reward a child who plans before computing. It is a foundational year, and it builds best when each skill gets its own turn.
That is the idea behind these worksheets. Whether your child is in Newark, Jersey City, Paterson, or Trenton, each PDF takes a single skill and gives it enough focused practice to take hold.
What’s on this page
This page holds 43 single-skill PDFs, each aligned to the New Jersey Mathematics Standards at Grade 4. Every file stays on one skill, so a student working on multiplicative comparison is not also fielding questions about angle measurement, and a student on adding fractions is not pulled away into rounding large numbers.
Each PDF begins with a one-page Quick Review that explains the skill in plain language and walks through a worked example step by step. Then come 20 practice problems that climb gradually from easy to harder, followed by 4 word problems that set the skill in a real-world context. The closing page is a student-facing answer key — short, friendly explanations a fourth grader can read alone and genuinely learn from.

How to use these worksheets at home
Keep the sessions short and let the steadiness carry the work. Fifteen minutes is plenty for a nine- or ten-year-old, and a calm fifteen minutes beats a tense forty-five every time. Pick one PDF, sit close by, and let your child do the work while you stay on hand for the stuck moments.
The habit that pays off most is pairing skills that lean on each other. Run “Adding Multi-Digit Whole Numbers” one day and “Subtracting Multi-Digit Whole Numbers” the next, and the second feels familiar rather than brand new. The same goes for “Equivalent Fractions” followed by “Comparing Fractions,” or “Area of Rectangles” right before “Perimeter of Rectangles.” When skills come in connected pairs, the connection itself does some of the teaching.
Save the answer key for after the work is finished, then go through it together. In a home in Paterson or a classroom in Trenton, that review step is where the learning truly lands — not in getting every problem right the first time, but in seeing clearly why a method works. Have your child explain one problem back to you in their own words; that small act is what turns a borrowed method into one they own.
It also helps to treat a wrong answer as useful information rather than a failure. If your fourth grader keeps stumbling in the same place — regrouping across zeros, lining up partial products, finding a common denominator — that is precisely the skill worth slowing down on. Because each PDF stays on one skill, you are never re-teaching an entire unit; you are repairing one specific thing and then moving forward.
A note about NJSLA at Grade 4
New Jersey fourth graders take the NJSLA — the New Jersey Student Learning Assessment — in Mathematics in the spring. It is built on the New Jersey Mathematics Standards, which are aligned to the Common Core, so the skills practiced on these worksheets and the skills measured on the test come from the same source.
The Grade 4 NJSLA asks students to do more than recall facts. It expects them to round and compare large numbers, carry out multi-digit multiplication and division, reason about factors and multiples, compare and combine fractions, work with decimals to the hundredths, and solve multi-step word problems where they have to choose the operation themselves. It also asks students to explain and apply their thinking, not just produce an answer. Because each PDF here targets a single standard, you can use the list as a checklist: spot the shaky skill, work just that one, and leave the rest alone.
A short closing
Fourth-grade math grows fast, but it grows in order, each skill leaning on the one before it. Bookmark this page, print a single PDF tonight, and let your child start somewhere small. New Jersey kids do hard things well when the next step is clear — and a worksheet on the kitchen table is about as clear as a next step gets.

Frequently Asked Questions
What topics are covered in these New Jersey Grade 4 worksheets?
Multi-digit multiplication, long division with one-digit divisors, place value to \(1{,}000{,}000\), equivalent and comparing fractions, adding and subtracting fractions with like denominators, multiplying fractions by whole numbers, decimals to hundredths, area and perimeter, measurement conversions, angle measurement, and multi-step word problems.
How do I print these worksheets?
Click any worksheet to open the PDF, then print from your browser (Ctrl/Cmd + P). Use 100% scale on letter paper so the boxes and number lines stay aligned. Most pages are one or two sheets – easy to staple into a short practice packet.
Are these worksheets really free?
Yes – every worksheet is a free PDF download. No login, no email, no paywall. Print as many copies as you need for home use or your classroom. Please don’t repost the PDF files on other websites.
Are these aligned with the New Jersey Student Learning Standards?
Yes. The pages follow the 2016 New Jersey Student Learning Standards for Mathematics at grade 4, the same standards NJSLA uses as its blueprint. That covers Operations and Algebraic Thinking, Number and Operations in Base Ten, Number and Operations – Fractions, Measurement and Data, and Geometry.
How often should my fourth grader practice?
For most kids, 15-20 minutes a day, four or five days a week, is the sweet spot. As NJSLA gets close, add a longer Saturday session a couple of weeks out so your child can practice pacing. Short and steady usually beats long and exhausting.
What if my child struggles with a worksheet?
Pause and walk through one problem together out loud. If a whole topic feels too hard, drop a level – review multiplication facts before long division, or equivalent fractions before adding fractions. Filling the missing prerequisite is faster than pushing through frustration.
Is there an answer key?
Yes – every worksheet PDF includes an answer key (usually on the last page or in a matching answer file). For fourth graders, walking through the steps together teaches more than just marking right or wrong.
How should we prep for NJSLA math specifically?
NJSLA includes Type I (short), Type II (modeling/reasoning), and Type III (extended performance) tasks, so practice writing out reasoning – not just circling answers. The biggest grade-4 content areas are multi-digit operations, fractions, and multi-step word problems.
Any tips for New Jersey parents new to fourth-grade math?
Three habits help most: (1) quick daily multiplication-fact drills, (2) talking about fractions and decimals at home (cooking, money, time), and (3) reading every word problem aloud before your child writes anything. Hearing the story almost always helps a fourth grader figure out the math.
Where can we get more grade 4 practice?
EffortlessMath has more grade 4 worksheets organized by topic, the Mastering Grade 4 Math workbook, and a focused Grade 4 Math Word Problems book. The Related Lessons section below links to step-by-step explanations of the trickiest fourth-grade skills.
