What Your Child Will Learn
- Apply the PEMDAS/BODMAS order of operations correctly to solve multi-step expressions containing parentheses, exponents, multiplication, division, addition, and subtraction
- Evaluate complex expressions with nested parentheses and multiple grouping symbols while maintaining proper sequence of operations
- Solve order of operations problems involving positive and negative exponents combined with fractions and mixed numbers
- Identify and correct common order of operations errors in expressions with three or more different types of operations
- Demonstrate mastery of operation precedence in real-world mathematical scenarios involving multiple computational steps
How to Use This Worksheet
- Step 1: Have students read through all 15 problems first to identify which contain the most complex nested operations, saving these for when they're most focused
- Step 2: For each problem, instruct students to annotate the expression by numbering the order in which operations should be performed according to PEMDAS
- Step 3: Work through problems 1-5 together, having students explain their reasoning for each step to ensure they understand the logic behind operation order
- Step 4: Allow independent practice on problems 6-10, checking answers after each problem to catch and correct mistakes before they become patterns
- Step 5: Complete problems 11-15 with students showing all work step-by-step, then review any incorrect answers by identifying exactly where in the order of operations the error occurred
Tips for Parents & Teachers
Watch for the common mistake of working left-to-right instead of following PEMDAS - have students circle or highlight each operation type in different colors before solving to visualize the correct sequence
When students encounter nested parentheses like [(3+4)×2]-5, teach them to work from the innermost parentheses outward, solving one layer at a time and rewriting the expression after each step
Address fraction confusion by reminding students that operations within fraction numerators and denominators must be completed before the division represented by the fraction bar
Help students avoid exponent errors by emphasizing that exponents only apply to the number or expression immediately before them - use parentheses to clarify what gets raised to a power
Frequently Asked Questions
My 7th grader keeps getting confused when there are both parentheses and exponents in the same problem - how can I help them?
Teach them to handle parentheses completely first (including any operations inside), then tackle exponents. For example, in (2+3)²×4, they should solve (2+3)=5 first, then 5²=25, then 25×4=100. Practice with problems that isolate these two operations before combining them.
What should I do when my child makes careless arithmetic errors while focusing on order of operations?
Separate the skill practice - first have them identify and number the correct order of operations without solving, then go back and carefully compute each step. This helps them master the sequencing before adding the pressure of accurate calculation.
How do I explain why multiplication and division have equal priority in PEMDAS?
Explain that MD and AS work left-to-right when they appear together because they're inverse operations with equal priority. In 12÷3×2, you work left-to-right: 12÷3=4, then 4×2=8. Use real examples like 'sharing 12 cookies among 3 people, then each person gets 2 more.'
My student struggles with expressions that have fractions mixed with other operations - any specific strategies?
Treat the fraction bar like parentheses - complete all operations in the numerator first, then all operations in the denominator, then divide. For complex fractions, work from innermost operations outward. Consider converting mixed numbers to improper fractions before starting.
When should my 7th grader use a calculator versus doing these problems by hand?
