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?
Decomposition
Abstraction
Pattern Recognition
Generalization
Look at the pattern: 3, 6, 12, 24, 48, ? What rule do you notice, and what comes next?
96
Which real-life example best shows decomposition?
Using a washing machine without knowing how it works
Dividing a project into research, writing, and presentation
Ignoring difficult steps in a process
Memorizing the whole textbook at once
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?
Decomposition
Automation
Pattern Recognition
Why do programmers use abstraction when writing code?
To make the code look longer and more detailed
To hide unnecessary details and focus only the important
To break problems into smaller parts
To test every single step manually
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?
Algorthims
Abstraction
Decomposition
Pattern Recognition
What is the missing shape?

Each shape is made of white and shaded squares and equals a number. Can you find the rule and calculate the missing value for the last shape?
14
Which real-life example best shows abstraction?
Using a steering wheel without thinking about the engine
Building a robot from scratch
Understanding every wire inside your phone
Fixing a car engine by yourself
🧩 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
Find the pattern rule and calculate the missing number :

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.
What does pattern recognition mean in computational thinking?
It means noticing what repeats or stays consistent.
