What Your Child Will Learn
- Apply the PEMDAS rule to solve multi-step expressions containing parentheses, multiplication, division, addition, and subtraction
- Identify which operation to perform first in complex expressions with multiple operations at the same level
- Solve expressions with multiple multiplication and division operations by working from left to right
- Evaluate expressions containing parentheses by completing operations inside grouping symbols before other operations
- Demonstrate mastery of order of operations by accurately solving 15 challenging problems without computational errors
How to Use This Worksheet
- Step 1: Review the PEMDAS acronym with your child and practice identifying which operation comes first in 2-3 sample problems together
- Step 2: Have your student work through the first 5 problems while explaining their thinking out loud, correcting any order mistakes immediately
- Step 3: Allow independent work on problems 6-10, checking answers after this set to address any emerging patterns of errors
- Step 4: Complete problems 11-15 independently, then review all incorrect answers by having your student identify where they deviated from PEMDAS
- Step 5: For any missed problems, have your student redo them while stating each step of PEMDAS as they work
Tips for Parents & Teachers
Use the acronym 'Please Excuse My Dear Aunt Sally' to help students remember PEMDAS, but emphasize that multiplication/division and addition/subtraction are equal and must be solved left to right when they appear together
Watch for the common mistake where students automatically do multiplication before division - remind them that when these operations appear together, they work left to right like reading a sentence
Have students circle or underline parentheses first, then number the operations in order before solving to prevent rushing through problems and making sequence errors
If students struggle with multi-step problems, have them rewrite the expression after each step to clearly see their progress and catch errors early
Frequently Asked Questions
Why does my 4th grader keep getting different answers even when they know PEMDAS?
This often happens because students rush through the left-to-right rule for multiplication/division and addition/subtraction. Remind them that when operations are at the same level (like 12 ÷ 3 × 2), they must work left to right, not just do multiplication first because it's in PEMDAS.
Should my child be using a calculator for these order of operations problems?
No, 4th graders should solve these mentally or with paper to strengthen their computational skills and focus on the sequence of operations. Calculators can actually make order of operations more confusing at this level since students need to understand the logical flow.
My child does well with simple PEMDAS but struggles with the harder problems on this worksheet. What's different?
The challenging problems likely have multiple operations at the same level (like several multiplication and division operations) or longer expressions. Practice breaking these into smaller steps and emphasizing the left-to-right rule when operations have equal priority.
How can I tell if my 4th grader is ready for this level of order of operations?
Students should be fluent with basic multiplication and division facts, comfortable with multi-digit addition and subtraction, and able to solve simple 2-step PEMDAS problems before attempting this challenging worksheet. If they're struggling with basic computation, work on those skills first.
What should I do if my child gets frustrated with these challenging problems?
