Break It Down โ€” Decomposition Master

What You'll Learn

๐Ÿ’ช Big problems become easy when you break them into small steps. Planning a birthday party seems overwhelming. To use this skill, follow these steps: First, understand the problem. Read it again if you need to. What is it really asking? Next, think about what you know. Have you seen something like this before? What worked last time? Then, come up with ideas. Try to think of at least TWO possible answers before picking one. The first idea isn't always the best! Finally, check your work. Does your answer make sense? Can you explain WHY you chose it? If you can explain your thinking, you really understand it. Remember: smart thinkers aren't people who never make mistakes โ€” they're people who LEARN from mistakes!
