In fourth grade, the questions get longer. A third-grade math problem usually has one step: do this, get an answer. A fourth-grade problem often hides a second step inside it — find the total first, then split it; multiply here, then compare. Learning to see that hidden structure, and to work through it without losing the thread, is the quiet heart of the year. The arithmetic inside each step is rarely the obstacle; the obstacle is holding the plan together from the first step to the last.
It shows up in every strand. Students multiply two- and three-digit numbers, divide with remainders, and find factors and multiples. They build equivalent fractions, compare them, add and subtract fractions with like denominators, work with mixed numbers, and multiply a fraction by a whole number. They read decimals to the hundredths, measure and classify angles, convert measurement units, build line plots, and find both area and perimeter. It is a foundational year — everything in fifth grade assumes a student carries this forward.
The good news is that this kind of multi-step thinking is built, not born, and it is built by getting each single step reliable first. A child who has to stop and think hard about 6 times 8 has no attention left for the structure of the problem. A child for whom that fact is automatic can spend all their focus on the plan. That is the case for steady, single-skill practice: it frees up the room a longer problem needs.
Whether your fourth grader is in Baltimore, Frederick, Rockville, or Gaithersburg, the work is the same and so is the approach: one clear skill at a time, with enough practice to make it hold.
What’s on this page
You will find 43 single-skill PDFs here, each aligned to the Maryland Mathematics Standards at Grade 4. Every file is built around exactly one skill, so attention does not get split. A student practicing long division is not also being quizzed on angles, and a student comparing fractions is not pulled into decimal place value. The narrow scope is what makes the practice land.
Each PDF opens with a one-page Quick Review — the skill in plain language, with one fully worked example. Then 20 practice problems climb from easy to genuinely challenging, followed by 4 word problems that put the skill in a real-world setting. The last page is a student-facing answer key: short, friendly explanations a nine- or ten-year-old can read alone and learn from, not just an answer column.

How to use these worksheets at home
The best approach with a fourth grader is modest and consistent. One PDF is one sitting, and one sitting is roughly fifteen minutes. A child who can see the finish line will get started — and getting started is most of the challenge.
Pair worksheets that build on one another, and each second page becomes a short step instead of a wall. “Adding Multi-Digit Whole Numbers” and “Subtracting Multi-Digit Whole Numbers” make a natural duo, sharing the same regrouping. Open a multiplication run with a place-value page — a child who reads 3,090 as three thousands and nine tens can see exactly why the partial products stack the way they do — and then move to “Multiplying by Two-Digit Numbers.” Set “Dividing with Remainders” right beside that, so division shows up as multiplication undone and the leftover becomes simply the part that would not make a full group.
Fractions reward a sequence, too. “Equivalent Fractions” belongs before “Comparing Fractions,” because renaming is the tool that makes comparing painless, and “Mixed Numbers” fits just after — a mixed number is only a whole and a fraction kept together. Let “Decimals to the Hundredths” sit next to fraction work so a child notices 0.25 and one-quarter are the same value in two outfits. In geometry, “Area of Rectangles” and then “Perimeter of Rectangles” lets a student feel the contrast between covering a space and going around it, while “Measuring Angles” before “Classifying Shapes” turns the names of triangles and quadrilaterals into something a child can reason out by looking.
After the page is done, hand the answer key to your student. In a Baltimore row house or a kitchen in Rockville, the routine works the same way: do the page, check it yourself, read the explanation for any mistake. That self-check is the step where understanding actually settles. It is worth revisiting old pages, too — every few weeks, have your child rework a handful of problems from a worksheet they finished a month back. A skill that held will run smoothly; one that slipped will surface, with time still on the calendar to set it right.
A note about MCAP at Grade 4
Maryland students take the Maryland Comprehensive Assessment Program (MCAP) Mathematics assessment in the spring. It is built on the Maryland Mathematics Standards, so the skills on these worksheets and the skills on the test are drawn from the same source.
The Grade 4 MCAP asks for reasoning, not just answers. Students explain place-value thinking, choose operations for multi-step word problems, compare fractions and justify the comparison, interpret remainders, and work with decimals, angles, area, perimeter, and the sorting of shapes. The questions tend to layer two or three ideas at once, which is exactly why practice that was understood — not merely completed — is what holds up under them. Because each PDF here is tied to a single standard, the spring window becomes a clear checklist — find the skills that wobble, work just those, and leave the steady ones alone.
A short closing
Fourth-grade math is not a single jump; it is a steady walk, taken one skill and one short afternoon at a time. No one page carries the year — but a page today, another in a few days, another after that, adds up to a child who steps into fifth grade already sure of the ground beneath them. Bookmark this page, print a PDF tonight, and let your student start small. Maryland kids do thoughtful, multi-step work well when the next step is clear — and a worksheet on the table makes it clear.

Frequently Asked Questions
What topics are covered in these Maryland 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 answer boxes and number lines stay aligned. Most pages are one or two sheets – easy to staple into a weekly practice packet.
Are the 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. We only ask that you don’t repost the PDFs on other sites.
Are these aligned with the Maryland College and Career-Ready Standards?
Yes. The pages follow the Maryland College and Career-Ready Standards for Mathematics at grade 4, the same standards MCAP 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 MCAP gets close, add a longer Saturday session so your child can practice pacing. Short and steady almost always beats long and exhausting.
What if my child struggles with a worksheet?
Pause and walk through one problem together out loud. If the 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 fighting through frustration.
Is there an answer key?
Yes – every worksheet PDF includes a worked 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 pages right or wrong.
How should we prep for MCAP math specifically?
MCAP includes selected-response, short constructed-response, and extended constructed-response items, so practice writing out the steps – not just circling answers. The biggest content areas at grade 4 are multi-digit operations, fractions, and multi-step word problems.
Any tips for Maryland 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 biggest fourth-grade skills.
