Fourth grade is where math starts to feel like it has weight to it. The problems run longer, the numbers run bigger, and the reasoning runs deeper. A student who was comfortable in the hundreds is now reading, rounding, and comparing numbers in the hundred-thousands. Multiplication has grown into a two- and three-digit procedure — and into a way of comparing quantities, the idea that one number can be a certain number of times another. Division now leaves remainders, and a fourth grader has to decide what those remainders mean in the problem at hand.
Fractions carry much of the year. Students learn to find equivalent fractions, to compare fractions with reasoning rather than a guess, to add and subtract fractions that share a denominator, and to multiply a fraction by a whole number. Decimals to hundredths follow close behind, linked back to fractions. Then come measurement and data, angles measured in degrees, and the geometry of lines, rays, and figures. For a nine- or ten-year-old, that is a full and demanding year — but it is made of separate, learnable pieces, and these worksheets take it exactly that way.
Each PDF gives a student one clear skill, with enough practice to make it stick and not so much that it becomes a slog.
What’s on this page
You will find 43 single-skill PDFs, each aligned to Grade 4 mathematics standards — the ACT College and Career Readiness Standards that the ACT Aspire assessment is built on, themselves aligned to the Common Core. Every file stays on one skill and nothing else, so a student practicing multi-digit multiplication is not also being quizzed on line plots, and a student working on comparing fractions is not pulled sideways into angles.
Each PDF opens with a one-page Quick Review that explains the skill in plain words and walks through a worked example from start to finish. Twenty practice problems follow, building gently from easy to harder, and then 4 word problems set the skill in a real context. The last page is a student-facing answer key, written so a fourth grader can check their own work alone and understand where a wrong answer came from — not just that it did.

How to use these worksheets at home
Keep the sittings short and regular. Fifteen minutes suits a fourth grader well; past that, you tend to be managing tiredness rather than teaching math. Pick a single PDF, sit close enough to help, and let your child carry the work while you stay on call for the stuck spots.
Running connected skills back to back helps a great deal — especially with a standards-based test like ACT Aspire, where the skills are designed to build on each other. Do “Adding Multi-Digit Whole Numbers” one afternoon and “Subtracting Multi-Digit Whole Numbers” the next, and the second feels like a small step rather than a new task. The same works for “Equivalent Fractions” before “Comparing Fractions,” or “Area of Rectangles” right before “Perimeter of Rectangles.” When skills come in pairs, the link between them does part of the teaching.
Keep the answer key aside until the work is done, then go through it together. That review — talking through why the right answer is right — is where the learning truly settles, far more than in a perfect first attempt.
A note about ACT Aspire at Grade 4
ACT Aspire is a standards-based assessment system used by member states and districts, with the mathematics test typically given in the spring. It is built on the ACT College and Career Readiness Standards, which are aligned to the Common Core State Standards — so the skills practiced on these worksheets and the skills measured on the test come from the same place.
The Grade 4 ACT Aspire mathematics test 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 hundredths, and solve multi-step word problems where choosing the right operation is much of the work. Because each PDF here targets a single standard, the full set works as a checklist: spot the shaky skills, work just those, and leave the solid ones alone.

A short closing
Fourth-grade math is a long stretch of road, but it is paved one skill at a time, and a child can keep pace with it that way. Bookmark this page, print a single PDF tonight, and let your student start somewhere small. 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 ACT Aspire Grade 4 worksheets?
Multi-digit multiplication, long division with one-digit divisors, place value through millions, 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 link to open the PDF, then print from your browser (Ctrl/Cmd + P). Use 100% scale on letter paper so problem layouts stay aligned. Most pages are one or two sheets – easy to staple into a weekly practice packet.
Are these worksheets free?
Yes – every worksheet is a free PDF. No signup, no email collection, no premium tier. Print as many copies as you need for one child or a whole class. Please don’t repost the files on other websites.
Are these aligned with ACT Aspire?
Yes. The pages map to ACT’s College and Career Readiness Standards at grade 4, the framework ACT Aspire is built on. Most Aspire states also use Common Core or close variants, so the math content lines up with what classrooms teach.
How often should my child practice?
For most fourth graders, 15-20 minutes a day, four or five days a week, is plenty. If Aspire testing is a few weeks away, add a longer Saturday session that mirrors test pacing. Don’t push through fatigue – tired kids don’t learn math, they just dislike it more.
What should I do if my child struggles?
Pause and walk through one problem together. If the whole topic is too hard, drop a level and rebuild the prerequisite – multiplication facts before long division, equivalent fractions before fraction addition. Missing prerequisites cause most fourth-grade frustration.
Is there an answer key?
Yes – every worksheet includes a worked answer key showing the steps, not just the final answer. For grade 4, walking through the steps with your child teaches more than handing back a graded page. Ask them to explain each step in their own words.
How is ACT Aspire scored?
ACT Aspire reports a scale score (400-460 at grade 4) and a Readiness Level (In Need of Support, Close, Ready, Exceeding). The grade-4 math readiness benchmark is currently 418. Schools also see strand-level performance so they know where to focus instruction.
Any tips for parents prepping for Aspire?
Three habits help most: (1) daily multiplication-fact drills (under 2 minutes), (2) reading word problems aloud before your child writes anything, and (3) asking “about how much should the answer be?” before solving. That last habit catches careless errors before they cost points.
Where can we find 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 clear explanations of the biggest fourth-grade math skills.
