Students correct three Halloween math computation errors — a fraction addition mistake, a division error, and a percent discount calculation. Part B has four questions about fraction vocabulary, decimal multiplication, and common denominators. Part C has two word problems about candy fractions and decimal multiplication for trick-or-treaters.
Correcting Halloween-themed fraction and decimal errors ensures students apply the same computation rigor to seasonal contexts as they do in regular math lessons.

Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A witch has 34 lb of candy corn and 112 lbs of chocolate, so she has 134 lbs total.
Rewrite: A witch has 34 lb of candy corn and 112 lbs of chocolate, so she has 214 lbs total.
2. Fix the sentence:
A haunted house earned $287.50 from tickets at $5.75 each, so 45 people visited.
Rewrite: A haunted house earned $287.50 from tickets at $5.75 each, so 50 people visited.
3. Fix the sentence:
Eight zombie costumes at $24.99 each with 15% off cost $179.93 total.
Rewrite: Eight zombie costumes at $24.99 each with 15% off cost $169.93 total.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A fraction with different top and bottom numbers like 34 is called a proper fraction.
2. Moving a decimal point one place to the right is the same as multiplying by 10.
3. To add 13 and 14, you first find a common denominator.
4. The answer to a division problem is called the quotient.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. A ghost collected 35 of a bag of candy on Elm Street and 23 of a bag on Oak Street. How much candy total? Show your work.
Find a common denominator: 35 = 915 and 23 = 1015. Then 915 + 1015 = 1915 = 1415 bags of candy.
2. Each trick-or-treater gets 0.75 lbs of candy. If there are 24 trick-or-treaters, how many pounds of candy are needed?
Multiply 24 × 0.75. 24 × 0.75 = 18 pounds of candy are needed.

★ Part C: Short Answer
Answer each question in one or two complete sentences.
1) A ghost collected 3/5 of a bag of candy on Elm Street and 2/3 of a bag on Oak Street. How much candy total? Show your work.
Find a common denominator: 3/5 = 9/15 and 2/3 = 10/15. Then 9/15 + 10/15 = 19/15 = 1 4/15 bags of candy.
2) Each trick-or-treater gets 0.75 lbs of candy. If there are 24 trick-or-treaters, how many pounds of candy are needed?
