This Grade 4 easy worksheet continues practice with two-operation PEMDAS problems and small twists like seven minus three plus two to teach the left-to-right rule for equal-rank operations. Students correct common mistakes, evaluate expressions step by step, and explain reasoning in short answers. The focus stays on simple whole numbers so Grade 4 learners build solid confidence in choosing which operation to compute first.

Order of Operations Introduction
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
9 + 3 x 2 equals 12 x 2 = 24 because we go left to right always.
Rewrite: 9 + 3 x 2 equals 9 + 6 = 15 because multiplication comes before addition.
2. Fix the sentence:
20 / 4 + 1 equals 20 / 5 = 4 since you add 4 + 1 first.
Rewrite: 20 / 4 + 1 equals 5 + 1 = 6 since division is performed before addition.
3. Fix the sentence:
For 7 - 3 + 2, you do 3 + 2 first to get 7 - 5 = 2.
Rewrite: For 7 - 3 + 2, work left to right: 7 - 3 = 4, then 4 + 2 = 6.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Evaluate: 10 + 5 x 4 = 30
2. Evaluate: 18 / 6 + 7 = 10
3. Evaluate: 15 - 2 x 6 = 3
4. In PEMDAS, the letter M stands for multiplication
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Explain why 6 + 4 x 2 is not equal to 20.
Because we must multiply 4 x 2 first to get 8, then add 6 for a total of 14.
2. When two operations have the same rank, how do you decide which to do first?
You work from left to right when operations share the same rank, like addition and subtraction.
