Free Thanksgiving Mental Math Worksheets for 3rd Grade

This is Set 4 of my 3rd grade mental math worksheets, covering worksheets 31–40.

Each worksheet includes a mix of all four basic math operations:

• Addition
• Subtraction
• Multiplication
• Division

The problems are mixed throughout each worksheet, so students get practice identifying which operation they need to use instead of completing a page of only one type of problem.

You Do Not Have to Complete the Sets in Order

One important thing to know about these mental math worksheets is that the sets do not progress in difficulty.

That means you can use Set 1, Set 2, Set 3, or Set 4 in any order. You do not need to finish worksheets 1–30 before using worksheets 31–40.

This makes it easy to choose whichever Thanksgiving-themed worksheets work best for your students’ current needs.

What’s Included in Set 4?

This Thanksgiving mental math set includes 10 printable worksheets, numbered 31–40.

Each page contains a variety of addition, subtraction, multiplication, and division problems appropriate for 3rd grade math practice.

The Thanksgiving theme adds a little seasonal fun while still keeping the focus on math skills.

These worksheets can be used for:

• Morning math
• Independent practice
• Bell work
• Math centers
• Homework
• Homeschool math
• Tutoring
• Early finishers
• Thanksgiving classroom activities
• Extra math practice
• Review before a math assessment

Mental math practice helps students become more comfortable working with numbers without relying on calculators or written-out steps for every problem.

Regular practice can help students improve their number sense, math fact fluency, computation skills, and confidence with basic operations.

For 3rd grade students, practicing all four operations is especially helpful as they continue building the foundational math skills they will use in more advanced problems.

Because these worksheets contain a mixture of operations, students also have to think about which operation makes sense for each problem.

Thanksgiving Math Practice for 3rd Grade

Thanksgiving is a great time to add seasonal activities to your regular math routine. Instead of putting math practice aside during November, you can use these Thanksgiving math worksheets to keep students practicing important skills while adding a fun holiday theme.

Use one worksheet at a time for quick daily practice, or print several worksheets at once and keep them ready for the entire Thanksgiving season.

Since the worksheets do not need to be completed in numerical order, you can easily mix them into your existing 3rd grade math curriculum.
