What is computational thinking?

• Decomposition

• Breaking down things that a computer has

• breaking down of information

• Breaking down of problems to make it so that a computer can understand it

Answer explanation

Computational thinking is the breaking down of big problems into smaller ones that even a computer can understand. Lets not mix this up with decomposition because of their similarities. Decomposition is breaking down complex problems into smaller, simpler problems. we use decomposition in things like math.

Jen wants to solve a math problem using the calculator on her computer. She inserts the following numbers: 7² + B² = 12²

This is....

• Arithmetic

• Logical

• Mathematical

• Pythagoras theorem

Answer explanation

This question involved: Abstraction and an arithmetic solution. Did we need to know her name? or the device she was using?

No, we didn't need to know either. We simply needed to know what the numbers used were.

How many types of problems are there?

• 4

• 5

• 2

What situation/s describes a chaotic problem?

• Covid-19

• Fire breaking out at school

• A Fight

• Getting yelled at by classmates

Answer explanation

Whenever we see a situation in which many variables, people or things are actively participating in along with a problem that seems to have no solution it is a chaotic problem.

Why can't a fight be chaotic?

This is because we already have a solution to stop it. By breaking/ splitting a fight it can be stopped. If it isn't stopped an outcome of one or both parties being harmed can be foreseen.

How do you think this could've been observed

• Pattern Recognition

• Decomposition

• Abstraction

• Logic

Answer explanation

Even though one can argue about it being decomposition; this is pattern recognition.

Wouldn't Newton have to observe the tides moving when the moon moves? wouldn't that mean that the moon's gravity pulls on our oceans causing high tide early in the morning and low tide later in the day?

Choose the aspect/s of a simple problem.

• Solution known

• solution unkown

• cause and effect is hard to find

• cause and effect is clear and easy to find

How to solve a computational problem?

• arithmetic solution

• math solution

• logic solution

• hardware solution

When writing down a recipe i exclude peppermint extract because it is optional and i don't want it in the cake. This is..

• Abstraction

• Algorithm

• Pattern Reognition

• Decomposition

Answer explanation

An ingredient isn't needed nor necessary but it is optional. So i decide to exclude it and focus on the more important ingredients instead

This picture is an example of...

• Abstraction

• Pattern Recognition

• Decomposition

• Algorithm

This is an example of..

• Abstraction

• Pattern Recognition

• Decomposition

• Algorithm
