Students correct three computation errors — 84 ÷ 4 = 22, 96 ÷ 3 = 31, and 175 ÷ 5 = 34. Part B has three fill-in-the-blank division problems: 72 ÷ 6, 135 ÷ 5, and 168 ÷ 8. Part C has two short-answer questions about the four steps of long division and how to check a long division answer.
Correcting off-by-one quotient errors and explaining the checking method builds the habits that make long division reliable.

Long Division
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
84 ÷ 4 = 22 because 4 goes into 84 twenty-two times.
Rewrite: 84 ÷ 4 = 21 because 4 × 21 = 84.
2. Fix the sentence:
96 ÷ 3 = 31 because 3 × 31 = 96.
Rewrite: 96 ÷ 3 = 32 because 3 × 32 = 96.
3. Fix the sentence:
175 ÷ 5 = 34 because 5 × 34 = 175.
Rewrite: 175 ÷ 5 = 35 because 5 × 35 = 175.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 72 ÷ 6 = 12
2. 135 ÷ 5 = 27
3. 168 ÷ 8 = 21
4. 256 ÷ 4 = 64
Part C: Short Answer
Answer each question in one or two complete sentences.
1. What are the four steps you repeat when doing long division?
Divide, multiply, subtract, and bring down. You repeat these steps until there are no more digits to bring down.
2. How can you check whether a long division answer is correct?
Multiply the quotient by the divisor and add any remainder. The result should equal the dividend.

★ Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1) Fix the sentence:
84 ÷ 4 = 22 because 4 goes into 84 twenty-two times.
Rewrite: 84 ÷ 4 = 21 because 4 × 21 = 84.
2) Fix the sentence:
96 ÷ 3 = 31 because 3 × 31 = 96.
Rewrite: 96 ÷ 3 = 32 because 3 × 32 = 96.
3) Fix the sentence:
175 ÷ 5 = 34 because 5 × 34 = 175.
Rewrite: 175 ÷ 5 = 35 because 5 × 35 = 175.
