Sharing means dividing things fairly and equally among people. In Computational Thinking, sharing is like breaking a big problem into smaller equal parts.
🍕 Real-Life Indian Example
Riya has 12 rotis. She shares them equally among 4 friends.
12 ÷ 4 = 3 rotis each
👉 Just like a computer divides a big task into equal small tasks!
Measuring helps us find the exact size of something using a unit. We measure different things in different ways:
🧠 CT Connection: Algorithm
When we measure step-by-step, we follow an Algorithm!
- Choose what to measure
- Pick the right unit
- Use the correct tool
- Record the result
When we measure many things, we can find patterns in the data. Computers do this too — it is called Pattern Recognition!
- All pencils are between 10–15 cm → Pattern found!
- Every 2 cups fill a jug → Repeated pattern!
- Every student gets 3 biscuits → Equal sharing pattern!
📝 Summary
- Sharing = Dividing equally = Decomposition in CT
- Measuring = Using units step-by-step = Algorithm in CT
- Finding patterns in data = Pattern Recognition in CT
- Computers also share tasks and measure data!

ISRO scientists measured the exact distance to the Moon before launching Chandrayaan! They used mathematical algorithms — just like the algorithms we learn in Computational Thinking. India's space scientists are real-life CT experts!
