Ask a fourth grader what they are working on in math and you will hear a longer list than you did a year ago. Place value stretched into the hundred-thousands. Multiplication that no longer fits on fingers. Division that sometimes leaves something over. Fractions that are not just slices of pizza anymore but numbers with weight, numbers you can compare and add. Fourth grade is the year math stops being a handful of separate tricks and starts becoming a connected system — and that connection is both the promise of the year and the part that can overwhelm a child.
Think about how much arrives at once. A fourth grader is asked to see that the 7 in 70,000 means something different from the 7 in 700, to multiply a four-digit number by a one-digit number without losing a place, to divide and then decide what the leftover actually means. At the same time, fractions become real numbers — 2/3 and 4/6 naming the same amount, 5/8 sitting clearly between 1/2 and 1 on the number line. Decimals to the hundredths show up as another way to write those same fractions. None of it is impossibly hard. There is just a lot of it.
That is what makes it a foundational year. A student who learns to multiply 4-digit numbers by 1-digit numbers, to divide with remainders and understand what the remainder means, to find factors and multiples, to build equivalent fractions and add fractions with like denominators, to read decimals to the hundredths place, and to measure angles and convert units — that student walks into fifth grade steady. A student who skipped past the shaky parts spends fifth grade catching up.
These worksheets are built for the steady route. Whether your fourth grader is in Sioux Falls, Rapid City, Aberdeen, or Brookings, they offer one skill at a time, clearly laid out, with room to practice until it holds.
What’s on this page
This page collects 43 single-skill PDFs, each aligned to the South Dakota Mathematics Standards at Grade 4. Every file is deliberately narrow — one skill, fully practiced — so a child working on number patterns is not also juggling line plots, and a child learning to add mixed numbers is not distracted by area formulas.
Each PDF opens with a one-page Quick Review: the skill explained plainly, with one example worked all the way through. After that come 20 practice problems arranged from easy to hard, then 4 word problems that drop the skill into a real-world setting. The final page is a student-facing answer key written for the student — short, friendly explanations a fourth grader can read on their own and learn from.

How to use these worksheets at home
Think in small, regular doses rather than big pushes. A South Dakota winter has plenty of long evenings, but a fourth grader does not need a long one — fifteen focused minutes with a single PDF does more than an hour of half-attention. Pick two afternoons a week, make them predictable, and let the routine do the heavy lifting.
When you can, run related skills back to back. “Multiplying by One-Digit Numbers” sets up “Multiplying by Two-Digit Numbers,” and a place value page first makes both go smoother, since lining up the digits is the whole game. “Equivalent Fractions” makes “Comparing Fractions” feel easy — once a child can rewrite 3/4 as 6/8, deciding whether it beats 5/8 takes no guessing. “Adding Fractions with Like Denominators” leads into “Subtracting Fractions with Like Denominators,” and both open the door to mixed numbers, which are just whole numbers carrying a fraction along. Divide-with-remainders practice belongs right after a straight division page, so the leftover gets treated as information. And area and perimeter are worth doing as a pair — same rectangle, one question about covering it and one about fencing it. Pairing cousins this way means each worksheet starts from familiar ground.
After a few of those arithmetic pairs, mix in the measurement and geometry pages — measuring angles, classifying shapes, reading decimals to the hundredths. They use a different part of a child’s attention, and that change of pace keeps the habit fresh.
One more thing worth doing: keep the answer key for the end. Let your child finish the page first, then check it themselves and read the explanations for anything they missed. That self-check moment — noticing the slip, understanding the fix — is where a worksheet turns into actual learning. And every few weeks, hand back an older worksheet and have them redo a few problems from memory, so a skill that has faded gets caught with months to spare.
A note about SBAC at Grade 4
South Dakota fourth graders take the Smarter Balanced (SBAC) Mathematics assessment in the spring. It is built on the South Dakota Mathematics Standards, so the work on these worksheets and the work on the test grow from the same root.
The Grade 4 SBAC is not a memory quiz. It asks students to reason — to solve multi-step word problems, to explain their thinking, to work through tasks that take more than one move to finish. It might ask a child to justify why two fractions are equivalent, to interpret what a remainder means, or to compare two decimals and say how they know. It pairs straightforward questions with deeper ones that ask a student to apply a skill in an unfamiliar place. Because each PDF here targets one standard, the spring window becomes a checklist you can actually use: see what is solid, see what is shaky, and spend practice time only where it is needed.
A short closing
Fourth-grade math is a real climb, but it is a gradual one — taken one skill, one short sitting at a time. The whole list does not have to be conquered in a week, and a single-skill page is permission to slow to the pace a child can actually hold. Bookmark this page, print one PDF tonight, and let your child begin somewhere small. South Dakota kids do hard things well when the path is clear, and a worksheet on the table is a clear path forward.

Frequently Asked Questions
What topics are covered in these South Dakota 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 weekly practice packet.
Are these worksheets really free?
Yes – every worksheet is a free PDF. No login, no email, no paywall. Print as many copies as you need for one child or a whole class. Please don’t repost the PDF files on other sites.
Are these aligned with the South Dakota standards?
Yes. The pages follow the South Dakota Content Standards for Mathematics at grade 4 (Common Core based), the same standards Smarter Balanced uses. 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 Smarter Balanced testing gets close, add one longer Saturday session a couple of weeks out so your child can practice pacing. Keep sessions short – tired fourth graders stop learning.
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.
Is there an answer key?
Yes – every worksheet PDF includes a full 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 Smarter Balanced math specifically?
Smarter Balanced is computer adaptive and includes drag-and-drop, equation-builder, and performance-task items along with multiple choice. Practice on a computer occasionally too, and make sure your child can show work on the performance task – that’s where many fourth graders lose points.
Any tips for South Dakota 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.
