South Carolina SC READY Grade 4 Math Free Worksheets: 72 Free Printable Worksheets with Answer Keys

There is a moment in fourth grade when a child stops counting and starts calculating. A third grader knows that six groups of seven is forty-two. A fourth grader takes that same fact and uses it to multiply 376 by 7, to divide 84 between four friends and notice there is a remainder, to figure out how many minutes are in a long car ride from Columbia to Charleston. The single facts are still there, but now they are tools rather than answers.

That shift runs through the whole year. Fourth graders read and compare numbers into the hundred-thousands, learning that the 6 in 264,000 is worth a hundred times the 6 in 2,640. They multiply and divide multi-digit numbers, and they meet fractions as real quantities they can compare, build, and add — not pictures of pizza, but numbers with a place on the number line. They see their first decimals, tenths and hundredths, and learn that 0.7 and 7/10 are two names for the same thing. They measure angles, classify triangles and quadrilaterals, and tell area from perimeter. It is a foundational year, the kind that quietly decides whether fifth-grade math feels manageable or overwhelming.

What can make it hard is not any single skill — it is the sheer number of them, arriving over a few short months. A child can feel capable one week and lost the next, simply because a new idea landed before the last one had time to settle.

These worksheets were made for exactly that. Wherever your fourth grader is doing homework — at a table in Greenville, on a porch in Mount Pleasant, in a classroom near the coast in Beaufort — they give one clear skill at a time, with enough practice for it to settle in before the next one arrives.

What’s on this page

You will find 43 single-skill PDFs, each aligned to the South Carolina College- and Career-Ready Standards for Mathematics at Grade 4. Every file holds one skill and nothing more, so a student practicing equivalent fractions is not also being asked to measure angles, and a student working on long division is not pulled sideways into decimals.

Each PDF starts with a one-page Quick Review that explains the skill in plain words and walks through a worked example. Then come 20 practice problems that climb from gentle to genuinely challenging, followed by 4 word problems that put the skill into a real situation. The last page is a student-facing answer key — not bare answers, but short, friendly explanations a nine- or ten-year-old can read alone and actually understand.

How to use these worksheets at home

The trick with fourth graders is to keep each sitting short and finishable. Fifteen minutes is plenty. One PDF, a sharpened pencil, and a quiet corner — that is the whole setup. A child who knows the work has an end in sight will lean into it; a child facing an open-ended hour will stall.

It helps to work in pairs that build on each other. Do “Adding Multi-Digit Whole Numbers” one afternoon and “Subtracting Multi-Digit Whole Numbers” the next, so the second feels like a continuation rather than a fresh start. Run a place value worksheet just before multi-digit multiplication, so the child already sees why lining up the digits matters. Pair “Equivalent Fractions” with “Comparing Fractions” — once a child can rename 1/2 as 4/8, deciding whether 3/8 is smaller becomes almost obvious — then follow with adding fractions and mixed numbers, since a mixed number is only a whole number wearing a fraction alongside it. Put “Area of Rectangles” next to “Perimeter of Rectangles” so covering a space and walking its edge stay distinct, and let multi-digit division sit beside a lesson on remainders, because the leftover is part of the answer. When two skills are cousins, learning them back to back makes both stick.

Once a handful of skills are steady, fold in the geometry and measurement pages — measuring angles, classifying shapes, reading decimals to the hundredths. A child often welcomes the change of pace.

Let your child use the answer key — after the work, not during. South Carolina families know the value of checking your own work before you hand it in. When a fourth grader reads the explanation for a problem they missed and says “oh, that’s where I went wrong,” that is the learning happening. Keep the key nearby, hand it over at the end, and let them grade themselves. It is also worth circling back: every couple of weeks, pull a worksheet your child finished a month ago and have them try a few problems again, so a skill that has quietly slipped gets caught early.

A note about SC READY at Grade 4

South Carolina fourth graders take the SC READY Mathematics assessment — the South Carolina College- and Career-Ready Assessment — in the spring. It is built directly on the South Carolina College- and Career-Ready Standards for Mathematics, which means the skills these worksheets practice and the skills the test measures come from exactly the same place.

The Grade 4 SC READY asks students to do more than recall procedures. It wants them to reason through a multi-step word problem, explain why two fractions are or are not equivalent, interpret a remainder, compare decimals to the hundredths, and choose a method that actually fits the question in front of them. Because each PDF here targets a single standard, you can treat the spring window as a checklist: if your child is solid on multi-digit multiplication but wobbly on fractions, or comfortable with area but unsure how to classify a quadrilateral, you can see that and spend your practice time exactly where it counts.

A short closing

Fourth-grade math grows fast, but it grows one skill at a time, and a child gets there one short sitting at a time. Neither you nor your child has to take all of it on at once. Bookmark this page, print a single PDF tonight, and let your fourth grader start somewhere small. South Carolina kids rise to real work when the next step is clear — and a worksheet on the kitchen table is about as clear as it gets.
