Grade 7 Order of Operations Worksheet - 10 Problems

What Your Child Will Learn

Evaluate complex numerical expressions containing exponents, nested parentheses, and multiple operations by strictly applying the order of operations rules
Simplify power expressions with combined operations such as multiplication of exponents and division within brackets at the G7 hard level
Identify and correct errors in expressions where students misapply exponent rules before multiplication or addition steps
Apply PEMDAS to solve 10 challenging problems involving powers, negative bases, and sequential operations in the Power Expression Champions worksheet

How to Use This Worksheet

Step 1: Review the PEMDAS acronym and highlight how exponents (powers) fit into the sequence before multiplication or division
Step 2: Guide the student through the first two problems on the Power Expression Champions worksheet, solving one operation at a time and writing intermediate results
Step 3: Have the student complete the remaining eight expressions independently, circling any exponents to ensure they are handled early
Step 4: Check answers together by recalculating each problem from left to right after exponents, discussing any differences

Tips for Parents & Teachers

Remind students that exponents must be calculated immediately after parentheses; a common mistake is performing multiplication first in expressions like 3^2 × (4 + 1), so have them underline exponents before proceeding

Address the error of expanding exponents incorrectly by practicing repeated multiplication on worksheet problems with powers greater than 2

For hard-level items with nested brackets and powers, encourage students to rewrite each step vertically to avoid losing track of operations

Frequently Asked Questions

How do exponents change the order of operations when parentheses are also present in a G7 expression?

Exponents are evaluated right after parentheses, so students must fully resolve any brackets first, then calculate powers before moving to multiplication or division.

What is a common mistake G7 students make with power expressions involving both multiplication and addition?

Students often multiply before handling the exponent, such as computing 2 × 3^2 as (2 × 3)^2 instead of 2 × 9; practicing with the worksheet helps reinforce the correct sequence.

Why is it important to handle negative bases carefully when evaluating powers in order-of-operations problems?

Negative signs can be misinterpreted as subtraction if not grouped in parentheses, so G7 students should treat -2^3 as -(2^3) unless parentheses clarify otherwise.

How can parents help a Grade 7 student who struggles with multi-step power expressions on a hard worksheet?

Break each expression into numbered steps, starting with parentheses, then exponents, and check one operation at a time to build accuracy with the Power Expression Champions problems.

What should students do if an expression has exponents inside parentheses at this difficulty level?

Resolve the parentheses first by evaluating the inner exponent and any other operations within the brackets before applying outer exponents or multiplications.
