Multiple Choice

Identifying the steps involved in solving a problem

• Abstraction

• Decomposition

• Pattern Recognition

• Algorithmic Thinking

Multiple Choice

Which of the following is an example of thinking computationally?

• Planning out your route when going to meet a friend
• When going to meet a friend, wandering around until you find them
• When going to meet a friend, asking a parent to plan your route for you

Multiple Choice

Looking for similarities and trends within a problem

• Abstraction

• Decomposition

• Pattern recognition

• Algorithmic Thinking

Decomposition

• Breaking the Problem into smaller chunks/parts.

• For baking a cake, that might involve thinking about the components of a cake (frosting, decorations, and the cake itself).

Pattern Recognition

•  Identify similarities, patterns, or trends that can help you solve the problem.

• For baking a cake, you might need to think about how many repeating layers the cake will have how did you create characters with past cakes you made.

Abstraction

• Remove any unnecessary details that don’t help you solve the problem.

• For baking cake, that might mean the order in which you mix/prepare the ingredients is not important.

• Not worrying about characters that have not arrived in mail yet because you know you can freeze your cake and add later.

Algorithm

• Writing down steps/directions to solve the problem "Formatting a general solution"

• For baking a cake: determining the steps to make the cake batter, frosting, and decorations, and then putting the completed components together to make the cake.

• For example, you wouldn’t decorate the cake before you frost it.

Multiple Choice

Multiple Choice

Computational thinking is the ability to solve problems by learning to think like a computer or a computer scientist. This involves analyzing a complex problem, developing possible solutions to the problem, and formatting the solutions so that they can be carried out by a computer (or a human). Which example is the "best" plan to solve a problem?

• 1. Create your Algorithm, 2. Look for trends, 3.Remove unnecessary parts, 4. Make sure you chunked the problem

• 1. Break down the problem into smaller parts. 2. Look for trends, 3.Remove unnecessary parts, 4. Write steps/directions to solve problem.

• 1. Break down the problem into smaller parts. 2. Look for trends, 3.Create an Algorithm, 4. Finally, remember to remove unnecessary parts.
