What Your Child Will Learn
- Apply the PEMDAS/BODMAS rule correctly to solve multi-step expressions involving parentheses, multiplication, division, addition, and subtraction
- Evaluate complex expressions with mixed operations by identifying which operations to perform first and in what order
- Solve challenging word problems that require translating written descriptions into numerical expressions and applying the correct order of operations
- Explain why the order of operations matters by demonstrating how different calculation sequences produce different answers
How to Use This Worksheet
- Step 1: Review the order of operations acronym PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction) with your student before starting. Create a reference card they can check throughout the worksheet.
- Step 2: For each problem, have your student identify ALL the operations present (parentheses, multiplication, division, addition, subtraction) and number them in the order they should be solved, rather than jumping straight to calculating.
- Step 3: Work through the first 2–3 problems together as examples, writing out each step on separate lines. For example, if the problem is 5 + 3 × 2, show: 'First: 3 × 2 = 6' and 'Then: 5 + 6 = 11.'
- Step 4: Guide your student to complete problems 4–7 independently, but require them to show their work for each step and label what operation they're performing. Check their answers and address any misapplications of the order of operations.
- Step 5: Challenge problems 8–10 may contain nested parentheses or multiple operation types. Have your student verbally explain their strategy before solving, then verify both the method and the answer.
Tips for Parents & Teachers
Many 4th graders rush through problems and skip the parentheses or perform operations left-to-right without considering order. Have students circle or underline each operation BEFORE solving, and require them to write down which rule they're applying at each step (e.g., 'Parentheses first,' 'Then multiply').
Students often struggle with expressions that have both multiplication AND division, or both addition AND subtraction, thinking one must always come before the other. Emphasize that multiplication and division have equal priority and are solved left-to-right, as are addition and subtraction. Practice this repeatedly with problems like 12 ÷ 2 × 3 versus 12 × 2 ÷ 3.
Use color-coding or vertical stacking to help students organize their work on harder problems. When they rewrite each step on a new line, they're less likely to lose track of what they've already calculated and less prone to arithmetic errors in complex expressions.
Watch for students who add or subtract before multiplying or dividing just because those operations appear first when reading left-to-right. Create anchor charts showing PEMDAS/BODMAS with clear examples, and revisit the rule before each problem during the worksheet.
Frequently Asked Questions
Why do we even need an order of operations? Can't students just solve problems however they want?
Without a standard order of operations, the same expression would give different answers depending on who solves it. For example, 2 + 3 × 4 would equal 20 (if you add first) or 14 (if you multiply first). The order of operations is a universal rule that ensures everyone gets the same correct answer. It's like a language rule—we all follow the same rules so we can communicate clearly.
My student keeps doing multiplication and division in the wrong order. How do I explain that they have equal priority?
Multiplication and division are inverse operations with equal priority, so you solve them left-to-right, whichever comes first. Use a concrete example: in 20 ÷ 4 × 2, solve from left to right: 20 ÷ 4 = 5, then 5 × 2 = 10. If you did multiplication first, you'd get 4 × 2 = 8, then 20 ÷ 8 = 2.5, which is wrong. Practice multiple problems where division comes before multiplication so the concept becomes automatic.
What should I do if my student gets the order right but makes an arithmetic mistake in the calculation?
Praise the correct process first! The order of operations is the focus of this worksheet, so if they chose the right operation to do first but miscalculated, circle the arithmetic error and have them redo just that one step. This helps them see that understanding WHEN to do an operation is different from performing the calculation correctly—both skills matter, but this worksheet emphasizes the first one.
These problems seem very difficult for Grade 4. Is that normal for a 'hard' difficulty worksheet?
Yes! Hard-difficulty order of operations problems for Grade 4 typically include multiple operation types, expressions with parentheses, and sometimes nested parentheses. They require students to hold the rule in mind while managing several calculation steps. This pushes advanced 4th graders and prepares them for algebra in later grades. If your student finds it challenging, that's appropriate—work through problems together and gradually release responsibility as confidence builds.
