1. Identify the components of Computational Thinking

• Thinking about the problem

• Pattern recognition
• Abstraction
• Decomposition
• Composition

2. Which component of computational thinking "looks for and finds similarities and trends within a problem"?

• Trending
• Abstraction
• Pattern recognition
• Composition

3. Which component of computational thinking " takes out all the details that don’t matter that much, allowing you to focus on just the details that do"?

4. When drawing a dog, which of the following characteristics is non-essential?

• Dogs have 4 paws
• Dogs have excellent hearing.
• Dogs have a tail
• Dogs can run fast.

5. Why do we need to look for patterns in problems?

• Patterns make it easier for us to solve complex problems.
• Patterns make it harder for us to solve complex problems.
• Patterns can be used to break the problem down into smaller parts.
• When we find the patterns, we can ignore it to solve the problem.
