🍁 Fall-Themed 4th Grade Math Worksheets

These worksheets are perfect for adding a little fall fun to 4th grade math practice.

Every page includes a cute, unique fall-themed icon. The decorations are simple and small enough to keep the worksheets focused on math while still making them feel festive for the season.

They’re a fun choice for September, October, and throughout the fall season when you want to bring a little seasonal personality into your math lessons.

🖨️ Printer-Friendly & Low-Ink Fall Worksheets

One of my favorite features of these fall math worksheets is that they are designed to be printer-friendly.

If you’ve ever printed a worksheet covered in large, colorful graphics, you know how quickly it can use up your printer ink!

These worksheets use small fall-themed decorations rather than large areas of color, so they still have a cute seasonal look without using a ton of ink. The little fall icons add festive fun without turning each worksheet into a full-color printing project.

If you’re a teacher, homeschool parent, or parent who prints lots of worksheets, you know how nice it is to have cute printable worksheets that don’t use up your entire ink cartridge!

✏️ What Skills Do These 4th Grade Math Worksheets Practice?

This set provides practice with the four basic math operations:

Addition

Students practice addition as part of the mixed-operation problems on each worksheet.

Subtraction

Subtraction problems give students continued practice with computation and accuracy.

Multiplication

Students can strengthen their multiplication skills and continue practicing multiplication facts.

Division

Division problems are mixed in with the other operations for additional practice.

Since the problems are mixed, students also have to pay attention to the operation they are being asked to solve.
