Rhode Island is a small state, but fourth-grade math is not a small year. It is the year a child’s number sense stretches in every direction at once — up into the millions, down into the hundredths, and sideways into fractions, factors, and the first real geometry. A third grader works mostly with whole numbers they can almost hold in their hands. A fourth grader has to think about quantities far larger and far smaller than that, and trust the rules even when the numbers stop being intuitive.
The year’s work is broad. Rhode Island fourth graders study place value into the large numbers, multi-digit multiplication and division with remainders, factors and multiples, and number patterns. Fractions become serious — equivalence, comparing, 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, along with unit conversions, area and perimeter, line plots, and the measurement of angles. Each topic is reachable on its own; the difficulty is in how steadily they keep coming.
In a classroom in Providence or at a kitchen table in Pawtucket, the dependable path is the same one — take a single skill, practice it until it feels easy, then take the next. These worksheets are built to keep that path clear.
What’s on this page
Here you will find 43 single-skill PDFs, each aligned to the Rhode Island Mathematics Standards at Grade 4. Each file is focused on one skill and nothing more. A worksheet on division with remainders does not also test fractions; a page on angle measurement stays right there. That focus is the point — it lets a child finish a page and genuinely feel finished.
Every PDF starts with a one-page Quick Review: the skill explained in plain words, with one example worked from beginning to end. Then 20 practice problems built from easy to hard, so confidence arrives before the challenge. Four word problems follow, placing the skill in a context a fourth grader can picture. The final page is a student-facing answer key — short, friendly explanations a nine- or ten-year-old can read alone and learn from, not just a list of answers.

How to use these worksheets at home
Keep the sittings short and the rhythm steady. Fifteen minutes on one page, a few times a week, will carry a fourth grader further than a long, dreaded session squeezed into a single afternoon. Kids this age concentrate best when the work has a clear finish line.
Running related skills back to back lets the connections surface. “Multiplying by One-Digit Numbers” and then “Multiplying by Two-Digit Numbers” — the second is simply the first with an added layer, and that becomes obvious when they sit a day apart. “Equivalent Fractions” before “Comparing Fractions” works the same way, since renaming a fraction is the exact tool that makes comparing two of them straightforward. “Area of Rectangles” paired with “Perimeter of Rectangles” lets a child feel the difference between covering a space and walking its edge.
Wherever home is — Warwick, Cranston, a quiet corner of the state — the habit most worth keeping is letting your child check their own work with the answer key once the problems are done. Reading why each answer holds is where the real learning happens. Sit nearby, keep the tone light, and let the explanations carry part of the load. It also helps to praise the corrections, not only the answers that were right from the start — a child who feels safe being wrong on the way to right will keep returning to the table without dread.
A note about RICAS at Grade 4
Rhode Island students take the Rhode Island Comprehensive Assessment System Mathematics test in the spring. It is built on the Rhode Island Mathematics Standards, so the skills on these worksheets and the skills the test measures come from a single shared source.
The Grade 4 RICAS asks for more than quick recall. Students are expected to multiply and divide multi-digit numbers, reason carefully with fractions, solve multi-step word problems, and explain the thinking that led to an answer. Because each PDF here targets one standard, the spring testing window becomes a checklist you can actually use — move through the skills, spot the shaky ones, maybe long division or fraction addition, and aim your practice precisely there.

Frequently Asked Questions
What topics are covered in these Rhode Island 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 home use or your classroom. Please don’t repost the PDF files on other sites.
Are these aligned with the Rhode Island standards?
Yes. The pages follow the Rhode Island Mathematics Standards at grade 4 (Common Core based), the same standards RICAS uses. RICAS itself shares its blueprint with Massachusetts MCAS, so the item style and content are very similar.
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 RICAS 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 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 fully 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 right or wrong.
How should we prep for RICAS math specifically?
RICAS uses selected-response and constructed-response items just like MCAS. Practice writing out the steps – not just circling answers. The biggest grade-4 payoff is fluent multi-digit operations, comparing fractions, and multi-step word problems.
Any tips for Rhode Island 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.
