The above problem covers some important points of problem solving.

  1. Identify: What is the question?
  2. Plan: What strategy will I use?
  3. Solve: Carry out your plan. Make your thinking visible.
  4. Check: Does my answer make sense?

Criteria for a Good Solution:

  • Is EFFICIENT. Doesn’t use unnecessary steps.
  • Provides an ACCURATE answer using numbers, pictures or words.
  • Shows your THINKING and calculations. Uses an effective strategy.
  • Proves that you UNDERSTAND the concept or topic.
  • Makes SENSE and is easy to understand.
