Winter Holiday Math & Reading — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Ben ate 13 of a pie and 13 more. He ate 26 of a pie because 13 + 13 = 26.
Corrected: Ben ate 13 of a pie and 13 more. He ate 23 of a pie because 13 + 13 = 23.
When denominators are the same, add only the numerators: 1 + 1 = 2. The denominator stays 3, giving 23.
2. Fix the sentence:
An icicle measured 1.2 meters. It melted 0.4 meters. Its new length is 0.6 meters because 1.2 − 0.4 = 0.6.
Corrected: An icicle measured 1.2 meters. It melted 0.4 meters. Its new length is 0.8 meters because 1.2 − 0.4 = 0.8.
Line up decimal points when subtracting: 1.2 - 0.4 = 0.8, not 0.6. Borrow from the ones place: 12 tenths - 4 tenths = 8 tenths.
3. Fix the sentence:
A ribbon is 250 centimeters. That equals 25 meters because 250 ÷ 100 = 25.
Corrected: A ribbon is 250 centimeters. That equals 2.5 meters because 250 ÷ 100 = 2.5.
There are 100 centimeters in every meter, so 250 ÷ 100 = 2.5 meters. Dividing by 100 shifts the decimal two places left.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Noah used 38 of a ribbon and his sister used 28 more. Together they used 58 of the ribbon.
Add the numerators when denominators match: 38 + 28 = 58.
2. A tree is 1.5 meters tall. After growing 0.5 meters, it is 2 meters tall.
1.5 + 0.5 = 2.0, which is just 2. Five tenths plus five tenths makes a whole.
3. A winter movie lasts 120 minutes. That equals 2 hours.
There are 60 minutes in 1 hour, so 120 ÷ 60 = 2 hours.
4. Five holiday cards cost $6 each. The total cost is $30.
5 × $6 = $30. You can skip-count by 6 five times: 6, 12, 18, 24, 30.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Amy shoveled 0.7 meters of snow. Then she shoveled 0.5 meters more. How many meters did she shovel? Show your steps.
Sample answer: Step 1: 0.7 + 0.5 = 1.2 meters. Amy shoveled 1.2 meters of snow in total.
Add the tenths: 7 tenths + 5 tenths = 12 tenths = 1.2 meters. Remember to carry when tenths total 10 or more.
2. Read: "The children laughed as they built a snowman with a carrot nose." What is the main idea?
Sample answer: The main idea is that children were having fun building a snowman. The carrot nose detail shows the happy, playful mood of their activity.
The main idea captures the most important point: children enjoying snowman-building. Specific details like 'carrot nose' support the happy mood.
