Add / subtract / multiply / divide

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Encourage students to talk through their thinking as they work: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These add / subtract / multiply / divide worksheets work well as daily practice, homework, or a focused review activity.

These add / subtract / multiply / divide worksheets for 4th grade give students the structured, hands-on practice they need to build confidence and fluency. Students work through a range of problem formats, from visual models and diagrams to written equations and word problems, so they encounter add / subtract / multiply / divide from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 4th grade. Practicing add / subtract / multiply / divide at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

This worksheet is designed for 4th Grade students (Ages 9-10), aligned to Common Core standard 4.OA.A.3. It can also be used as review for early students at the next grade level or as an introduction for advanced students.

Yes. This worksheet works for homeschool, classroom, and tutoring settings. Print individual pages for targeted practice, or print the full set as a packet. Works great as a morning warm-up, independent center activity, or fast-finisher task.

Fourth graders should understand that mathematical expressions must be evaluated in a specific order to get a consistent answer. While the full PEMDAS rules are typically formalized in fifth grade, fourth graders learn to evaluate expressions involving parentheses and the four basic operations. Per CCSS 4.OA.A.3, they should use parentheses to indicate which operations to perform first and understand that expressions with parentheses can have different values than the same expressions without parentheses. For example, 3 times (4 plus 2) equals 18, but 3 times 4 plus 2 equals 14. Worksheets that present pairs of expressions with and without parentheses and ask students to evaluate both help children see why order matters in mathematics.

Start with a story context: "You buy 3 bags of apples. Each bag has 4 red and 2 green apples. How many apples total?" Show that the answer is 3 times (4 plus 2) equals 3 times 6 equals 18. Then compare to 3 times 4 plus 2 equals 14, which represents buying 3 bags of 4 apples and then adding 2 more. This shows that parentheses change the meaning and the answer. Practice with simple expressions first, using only addition and multiplication. Worksheets that ask students to place parentheses to make an equation true (like inserting parentheses into 2 plus 3 times 4 equals 20) develop critical thinking about expression structure. Always connect to real-world scenarios so students understand that order of operations reflects how problems are structured.

The most common error is evaluating left to right without respecting operation hierarchy: solving 3 plus 4 times 2 as 7 times 2 equals 14 instead of 3 plus 8 equals 11. Another frequent mistake is forgetting to complete the operation inside parentheses before proceeding. Some children also apply operations to the wrong numbers when an expression has multiple steps. Worksheets that require students to show their work step by step, circling or underlining the operation performed at each step, help prevent these errors. Providing expressions that have been solved incorrectly and asking students to find the mistake builds error-detection skills. Practice with a mix of expressions, some requiring left-to-right evaluation and others requiring parentheses-first evaluation, builds flexible and accurate computation habits.
