Solution: Exercises 4 to 5
4 Comparison Practice
Exercise 4
Sam has 14 toy cars. Ben has 9 toy cars. How many more cars does Sam have than Ben?
Definition:

Comparison word problem: A problem that asks for the difference between two quantities

Given
14 - 9 = ?
Operation
Subtraction
Result
5
Step 1: Identify what we know

Sam has 14 cars, Ben has 9 cars

Step 2: Identify the question

"How many more" means find the difference

Step 3: Set up the equation

14 - 9 = 5

Step 4: State the answer

Sam has 5 more cars than Ben

Sam has 5 more cars
Final answer:

Sam has 5 more cars than Ben

Applied rules:

• Comparison problems: "How many more" indicates subtraction

• Subtraction in context: Finding the difference between quantities

• Problem interpretation: Understanding what the question is asking

5 Challenge Practice
Exercise 5
There are 15 children on the playground. 6 children go inside for lunch and then 4 more children come out to play. How many children are on the playground now?
Definition:

Challenge problem: A complex problem combining multiple operations and steps

First operation
15 - 6 = 9
Second operation
9 + 4 = 13
Final answer
13 children
Step 1: Identify the sequence of events

Start with 15, 6 go inside, then 4 come back out

Step 2: Solve the first operation

15 - 6 = 9 (after 6 children go inside)

Step 3: Solve the second operation

9 + 4 = 13 (after 4 children come out)

Step 4: State the final answer

There are 13 children on the playground now

Questions & Answers

Question: My child reads word problems but doesn't know which operation to use. How can I help them identify the correct operation?

Answer: Help your child recognize key words that indicate operations:

  • Addition words: more, total, altogether, sum, in all, combined
  • Subtraction words: left, take away, give, spend, eat, fewer, difference
  • Practice: Create flashcards with key words and operations
  • Visualization: Draw pictures to show what's happening

Encourage your child to read the problem multiple times and ask "What is happening in this story?"

Question: Word problems seem so hard! Why can't I just do regular math problems?

Answer: Great question! Word problems are actually very useful:

  • Real-world connection: Math happens in everyday life
  • Critical thinking: You learn to analyze situations
  • Problem solving: You develop logical thinking skills
  • Preparation: You'll need these skills for harder math later

Think of word problems as stories with math in them - they help you see how math works in real life!

Question: How can I provide effective practice opportunities for word problems?

Answer: Provide effective practice with these strategies:

  • Vary the contexts: Use different real-world scenarios
  • Gradual complexity: Start simple and increase difficulty
  • Regular practice: Consistent exposure builds fluency
  • Peer collaboration: Have students discuss problems together

Focus on building confidence through repeated success with varied problem types!
