Free Grade 4 Math Worksheets: 43 Printable PDFs with Answers

Download 43 free printable Grade 4 math worksheets with answer keys. Choose practice in place value, multiplication, division, fractions, decimals, measurement, angles or geometry. Each topic opens a separate PDF without an email signup or purchase.

Find matching lessons and review tools in the Grade 4 Math Online Center. The original 4th Grade Mathematics Worksheets collection contains a different set of files; both collections remain available.

How to download, print and find answers

Open a worksheet link, then use your PDF viewer’s download or print control. Each file starts with a quick review and worked example, followed by practice and word problems. The final page is a book promotion, so it can be left out of your print range.

For 39 worksheets, student work is on page 1 and the answer key with explanations is on page 2. Four files have student work on pages 1–2 and answers on page 3: Multiplicative Comparison Word Problems, Multi-Step Word Problems, Classifying Quadrilaterals, and Lines of Symmetry. Keep the answer page separate until the student has attempted the questions.

• Lines of Symmetry, [4.G.A.3] find the lines that fold a shape onto itself

Build a short practice sequence

For multiplication, begin with Multiplying by a One-Digit Number before Multiplying Two Two-Digit Numbers. For fractions, try Equivalent Fractions before Comparing Fractions; practice addition with like denominators before mixed-number addition and subtraction. Pair Area of Rectangles with Perimeter of Rectangles to compare square units with units of length.

Ask the student to explain the worked example, try a few questions independently, then compare the method with the answer explanation. When an answer differs, identify the step that caused it—a place-value column, denominator, operation or unit—and review that skill in the Grade 4 Online Center. Adjust the amount of practice to the learner rather than requiring every worksheet in order.

Grade 4 topics and curriculum fit

The Common Core Grade 4 overview emphasizes multi-digit arithmetic, fractions and geometric properties. This collection also includes decimals, measurement, data and angles. Topic references do not establish complete coverage of every standard or state assessment. Match the selected practice to your school’s curriculum and current state guidance.
