Louisiana LEAP Grade 4 Math Free Worksheets: Free PDF Math Worksheets with Clear Answer Keys

Fourth-grade math is a little like learning to read a longer book. The letters are the same ones a child already knows, but now the sentences run on, the chapters connect, and you have to hold an idea in mind while you work through the next part of it. The arithmetic is familiar; what is new is the length and the linking. A two-step word problem is not harder arithmetic than a one-step problem — it just asks a child to keep the first answer in hand while they go looking for the second.

You see it across the whole year. Students multiply two- and three-digit numbers, divide and make sense of what is left over, and find the factors and multiples tucked inside ordinary numbers. They build equivalent fractions and 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, tell area from perimeter, convert units of measurement, and reason through word problems that ask for more than one step. It is a foundational year — fifth grade leans on every piece of it.

That weight is exactly why the year rewards patience over speed. A skill rushed through in a week tends to wobble later; a skill given a calm fifteen-minute page, then revisited once or twice more, tends to hold. The goal is not to cover everything fast — it is to leave each skill steady enough that the next one has something to stand on.

In New Orleans or Baton Rouge, in Shreveport or Lafayette, or in a small town along a bayou road, the work asks the same thing of a fourth grader: take it one clear skill at a time.

What’s on this page

There are 43 single-skill PDFs here, each aligned to the Louisiana Mathematics Standards at Grade 4. Every file is deliberately narrow — one skill and nothing else. A student practicing multi-digit subtraction is not also juggling fractions; a student measuring angles is not pulled toward decimal place value. That focus is what makes a short practice session actually productive.

Each PDF begins with a one-page Quick Review that lays out the skill in plain language and works one example from start to finish. Then there are 20 practice problems that build from easy to challenging, and 4 word problems that set the skill in a real context. The last page is a student-facing answer key — short, encouraging explanations a student can read on their own, not just a column of answers.

How to use these worksheets at home

Keep it small and keep it regular. One PDF is one sitting, and one sitting is about fifteen minutes. A fourth grader does much better with a short task that has an end in sight than with a vague stretch of “math time.”

Group skills that build on each other, and the second page in a pair feels like a small step rather than a fresh climb. “Adding Multi-Digit Whole Numbers” pairs naturally with “Subtracting Multi-Digit Whole Numbers,” since both rely on the same regrouping. Start a multiplication stretch with a place-value page — a child who knows the 7 in 4,700 means seven hundreds can actually see why the partial products line up the way they do. Then run “Multiplying by Two-Digit Numbers” close to “Dividing with Remainders,” so division reads as multiplication taken apart, with the remainder as the leftover that did not fit a whole group.

Fractions reward an order, too. “Equivalent Fractions” should come before “Comparing Fractions,” since renaming is the move that makes comparing simple, and “Mixed Numbers” sits comfortably right after — a mixed number is just a whole and a fraction side by side. Let “Decimals to the Hundredths” follow fraction work so a child sees that 0.75 and three-quarters mark the same point. In geometry, “Area of Rectangles” followed by “Perimeter of Rectangles” helps a student feel the difference between covering a shape and tracing its edge, and “Measuring Angles” before “Classifying Shapes” gives a child the eye they need to tell a right triangle from an obtuse one.

When the page is finished, the answer key is the student’s tool, not yours. At a table in Lafayette or anywhere after supper, let your child check their own work and read through the explanation for any miss. That self-check, done calmly, is the part that turns practice into understanding. It also pays to loop back: every few weeks, pull a page your child finished earlier and have them try a few problems again. A skill that has held will flow; one that has faded will show itself, early enough to fix without any drama.

A note about LEAP at Grade 4

Louisiana students take the LEAP Mathematics assessment in the spring. It is built on the Louisiana Mathematics Standards, so the skills on these worksheets and the skills on the test trace back to exactly the same place.

The Grade 4 LEAP asks students to do real mathematical thinking — explaining place-value reasoning, choosing operations for multi-step problems, comparing fractions and justifying the result, interpreting remainders, and working through decimals, angles, area, perimeter, and shape classification. Its questions often stack two or three ideas together, which is why practice that was genuinely understood — not just finished — is what carries a child through them. Since each PDF here is tied to one standard, the spring testing window can serve as a plain checklist: spot the shaky skills, practice just those, and leave the steady ones be.

A short closing

Fourth-grade math is a long read, not a sprint — it comes together one skill, one short afternoon at a time. No single page decides the year; it is the steady accumulation, page after page, that leaves a child standing on solid ground when fifth grade arrives. Bookmark this page, print a PDF tonight, and let your student start small. Louisiana kids do careful, connected work well when the next step is clear, and a worksheet on the table makes it clear.
