When solving a big problem, what is the main purpose of decomposition?
To break it into smaller, easier parts that can be solved step by step.
Which real-life example best shows decomposition?
Using a washing machine without knowing how it works
Dividing a project into research, writing, and presentation
Memorizing the whole textbook at once
Ignoring difficult steps in a process
When you plan to build a robot by dividing the work into smaller tasks — like sensors, movement, and coding — which computational thinking skill are you using?
Decomposition
Abstraction
Algorthims
Pattern Recognition
Find the pattern rule and calculate the missing number :
2
Why do programmers use abstraction when writing code?
To make the code look longer and more detailed
To test every single step manually
To hide unnecessary details and focus only the important
To break problems into smaller parts
What does pattern recognition mean in computational thinking?
It means noticing what repeats or stays consistent.
A student analyzes several math problems and notices they all follow a similar process to find the solution. Which computational thinking skill is the student applying?
Automation
Decomposition
Pattern Recognition
🧩 Look carefully at the 3D trailer made of cubes. From the side, top, and back views, you can see how the cubes are arranged. 👉 How many cubes are there in total?
51 cubes
You are creating a robot that sorts colored balls and placing it in the right box. Then, the robot repeats the same motion .. Which two computational thinking skills did you use in this task?
Decomposition and Pattern Recognition
When you predict what color will come next in a traffic light (red → yellow → green → …), which computational thinking skill are you using?
Abstraction
Generalization
Pattern Recognition
Decomposition
Which real-life example best shows abstraction?
Fixing a car engine by yourself
Understanding every wire inside your phone
Building a robot from scratch
Using a steering wheel without thinking about the engine
