# 01 - Computational Thinking and Theory

1. Computational thinking is the art of a human being able to think like a computer (e.g. in binary using 1s and 0s).

True

False

2. Computational thinking is a ….

way of computing big numbers and adding them up faster than a computer would

way of computing things in binary and not the alphabet

way of thinking with numbers as opposed to with words

way of thinking about a problem to understand it and then logically working out a good solution

3. There are generally speaking four elements of computational thinking. What are they?
```Elements of Computational Thinking
==================================
1. Decomposition
2. Pattern recognition
3. Abstraction
4. Algorithmic thinking
5. Binary number conversion
7. Subtraction```

3,4,5,6

4. Read the excerpt on computational thinking (from Barefoot Computing) and see if you agree.
```For example, if you’re going to make an animation, you need to start
by planning the story and how you’ll shoot it before you can use
computer hardware and software to help you get the work done. The
thinking that is undertaken before starting work on a computer is
known as computational thinking.```

True

False

5. Computational thinking is not thinking about computers or like computers. Computers don’t think for themselves. Not yet, at least!

FALSE

TRUE

6. Why is computational thinking so important?
```Computer scientists are interested in finding the most ____________way
to solve problems. They want to find the best solution that solves a
problem correctly in the fastest way and using the least amount of
resources (time/space).```

tiring

time consuming

efficient

7. Read the alternative definition of the stages in computational thinking and fill in the blanks.
```Elements of Computational Thinking
==================================
Another characterisation of computational thinking is a process
based on three stages:

A___________: problem formulation (leaving out the irrelevant details);
Automation: solution expression; and
Analysis: solution execution and evaluation.```

Absailing

Abduction

Abortion

Abstraction

8. Two important parts of computational thinking are: 1. Logically organizing and analyzing data and 2…...

Breaking the problem down into smaller parts

Taking the problem to combine it with other bigger problems

Comparing the problem to all the other problems in the entire world

Breaking the problem into bigger problems and parts

9. Another definition of compuational thinking is as follows: The ____________ involved in formulating a problem and expressing its solution(s) in such a way that a computer—human or machine—can effectively carry it out

CPU logic

thought process

binary arithmetic

boolean gates

10. If you have the time, feel free to watch this educator's guide to computational thinking. What is algorithm design?

There is no such thing

Developing the step by step instructions for solving this and similar problems

Developing binary arithmetic techniques to help the computer add up

Developing fast techniques to add two numbers together
