5 Word Problem
Exercise 5
If Alex can complete 15 puzzles in 45 minutes and Ben can complete 10 puzzles in 30 minutes, who has higher puzzle-solving productivity?
Definition:

Multi-step problem: Requires calculating rates and comparing

Productivity rate: Puzzles completed per minute

Alex's Rate
15 ÷ 45 = 0.33
Ben's Rate
10 ÷ 30 = 0.33
Step 1: Calculate Alex's rate

Alex: 15 puzzles ÷ 45 minutes = 0.33 puzzles per minute

Step 2: Calculate Ben's rate

Ben: 10 puzzles ÷ 30 minutes = 0.33 puzzles per minute

Questions & Answers

Question: What does work capacity mean? Is it how much work I can do?

Answer: Yes! Work capacity is exactly how much work you can do. It includes:

  • How much: The amount of work you complete
  • How fast: How quickly you finish tasks
  • How hard: How much effort you put in

Example: If you can solve 5 math problems in 10 minutes, that's your work capacity for math problems.

Your work capacity helps teachers understand how much you can accomplish!

Question: My child struggles with comparing productivity. Any tips to help them understand?

Answer: Here are helpful strategies for productivity comparison:

  • Count completed tasks: Focus on how many things got done
  • Same time rule: If time is the same, more work = higher capacity
  • Calculate rates: For different times, divide work by time
  • Real-life examples: Compare reading pages, solving problems, etc.

Example: If both work for 10 minutes, the one who completes more has higher capacity.

Practice with simple activities like counting how many problems each person solves.

Question: Why do we divide work by time to get the rate?

Answer: Dividing work by time tells us how much work gets done per minute:

  • Rate means: How much per unit time
  • Example: If you do 6 problems in 3 minutes, you do 2 problems per minute
  • Formula: Work ÷ Time = Rate

This makes it fair to compare people who worked for different amounts of time.

Someone who does 10 problems in 5 minutes (rate: 2) is faster than someone who does 8 problems in 5 minutes (rate: 1.6).

Rates let us compare productivity fairly!

Question: What if someone works harder but finishes less? Who has higher capacity?

Answer: Good question! Work capacity measures what gets completed, not just effort:

  • Completed work: What matters for capacity measurement
  • Effort: How hard someone tries (important but separate)
  • Productivity: Actual work finished per time

Example: If someone tries very hard but finishes fewer problems, they have lower capacity for that task.

However, effort is still important and shows good work habits!

Capacity measures results, effort shows attitude.

Question: Can work capacity change? Can I get better at doing work?

Answer: Yes! Work capacity can definitely improve:

  • Practice: The more you practice, the faster you get
  • Skills: Better methods make you more efficient
  • Focus: Concentrating helps you do more
  • Experience: You learn to work smarter

Example: You might solve 2 math problems per minute now, but with practice, you might solve 3 or 4 per minute.

This is why we practice - to improve our work capacity!

Your capacity will grow as you learn and practice more!
