Free Math Worksheets for 3rd Graders: Practice Addition, Subtraction & More

Third grade is where math stops being just counting and starts becoming real problem-solving. Your child is expected to add and subtract numbers up to 1,000, start learning multiplication and division, and tackle multi-step word problems — all in one year.

That's a big jump from second grade. And if gaps form in addition or subtraction now, they compound fast. The good news: short, focused daily practice is the single most effective thing you can do at home to keep your 3rd grader on track.

Below you'll find free printable math worksheets organized by the core 3rd grade skills, with sample problems so you can see exactly what your child should be working on.

What 3rd Graders Need to Master

Third grade math standards (Common Core and most state standards) focus on four big areas. Here's what matters most — and where kids most commonly struggle:

Multi-Digit Addition

Adding 2- and 3-digit numbers with regrouping (carrying). This is the foundation for everything that follows.

Multi-Digit Subtraction

Subtracting with borrowing across zeros. The #1 skill kids struggle with in 3rd grade math.

Intro to Multiplication

Understanding multiplication as groups of equal size. Times tables for 0-10. Arrays and skip counting.

📚

Word Problems

One- and two-step problems using addition, subtraction, and early multiplication. Reading comprehension meets math.

Sample Worksheet: 3-Digit Addition with Regrouping

Regrouping (carrying) is where most 3rd graders first hit a wall. The concept is simple, but it requires careful tracking of place values. Here's a sample:

Grade 3 · Addition with Regrouping
8 Problems
1
347 + 285 = 632
2
518 + 394 = 912
3
672 + 159 = 831
4
463 + 278 = 741
5
195 + 637 = 832

Sample Worksheet: Subtraction with Borrowing

Subtraction with borrowing — especially borrowing across a zero — is the trickiest skill for most 3rd graders. If your child can handle these confidently, they're in great shape:

Grade 3 · Subtraction with Borrowing
8 Problems
1
503 − 247 = 256
2
800 − 365 = 435
3
712 − 448 = 264
4
600 − 283 = 317
5
941 − 576 = 365

Word Problems: Where Math Meets Real Life

Word problems trip up a lot of 3rd graders — not because the math is hard, but because they have to figure out which operation to use. That's actually the most important math skill of all: knowing when to add, subtract, or multiply.

Here are three examples at the 3rd grade level:

Practicing word problems daily — even just 2 or 3 — builds the problem-solving muscles that carry into 4th grade and beyond.

Tips for Parents: Making Math Practice Stick

Worksheets work, but how you use them matters as much as what's on them. A few things we've learned from talking to hundreds of parents:

Generate Worksheets Matched to Your Child's Level

Every 3rd grader is different. Some are nailing multiplication but struggling with borrowing. Others need more word problem practice. Generic worksheets don't adapt — but BrightPrint does.

Frequently Asked Questions

What math should a 3rd grader know?

By the end of 3rd grade, students should be fluent in addition and subtraction within 1,000, understand basic multiplication and division concepts (times tables up to 10), work with simple fractions, tell time, count money, and solve one- and two-step word problems. Multi-digit addition and subtraction with regrouping is a core skill.

How can I help my 3rd grader with math at home?

Short daily practice (10–15 minutes) is more effective than long weekly sessions. Focus on one skill at a time. Use worksheets with answer keys so your child can self-check. Real-world math like grocery shopping, cooking measurements, and counting change reinforces classroom learning naturally.

How many math problems should a 3rd grader do per day?

10–20 problems per day is the sweet spot. More than that leads to fatigue and careless errors. If your child is getting most problems right, increase difficulty rather than volume. If they're struggling, reduce to 5–10 problems and focus on understanding the concept.

What is the difference between 3rd grade and 4th grade math?

3rd grade focuses on addition/subtraction fluency within 1,000 and introduces multiplication and division. 4th grade expects multiplication and division fluency, introduces multi-digit multiplication, long division, equivalent fractions, and decimals. Solid 3rd grade foundations prevent struggles later.
