• Click it because it's pink.

• Repeat my steps with LESS puzzle pieces.

• Looks kind if weird.

Define PATTERN RECOGNITION.

• A sequence of instructions.

• Looking for similarities and trends.

• Breaking a task into smaller tasks.

• Focusing on what is important and ignoring what is unnecessary.

Define DECOMPOSITION

• Breaking a task into smaller tasks.

• Looking for similarities and trends.

• A sequence of instructions.

• Focusing on what is important and ignoring what is unnecessary.

Why is Pattern Matching important to Computer Science?

• It helps us solve problems that have repeated actions

• It helps us write loops

• It helps us write algorithms in fewer steps by looping repeated steps.

• All of these

George wanted to make a robot that prepared him a bowl of ice cream every day when he got home from work.He noticed that the robot made the same motion over and over again. He decided to loop that behavior in his program. What part of Computational Thinking was she using?

• Abstraction

• Decomposition

• Algorithm

• Pattern Matching

What is the purpose of Computational Thinking?

• To confuse us

• To help us solve only Computer Science problems

• To help us with out homework

• To help us solve any problem that we are faced with
