This Grade 4 medium worksheet introduces parentheses and three-operation expressions in a clear, structured way. Students compare expressions like (5 + 3) x 2 with 5 + 3 x 2 to see how parentheses change answers dramatically. They evaluate longer expressions and match expressions to their values. The matching activity reinforces careful reading of each expression so Grade 4 students recognize how grouping affects the final calculated result every time.

Order of Operations Introduction
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Evaluate: (5 + 3) x 2 = 16
2. Evaluate: 5 + 3 x 2 = 11
3. Evaluate: (10 - 4) / 2 = 3
4. Evaluate: 8 - 2 + 5 x 3 = 21
5. Evaluate: 12 / (2 + 2) = 3
6. Evaluate: 4 x (6 - 1) = 20
7. Evaluate: 9 + 6 / 3 - 1 = 10
8. The expression (3 + 2) x 4 equals 20
9. Without parentheses, 3 + 2 x 4 equals 11
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
