🏷️ Data Types for Kids
Different kinds of stuff need different kinds of boxes.
Why Types?
You wouldn't store ice cream in a cardboard box. Different things need different containers. Code is similar — numbers, words, and yes/no answers all behave differently, so we use different "types" of boxes.
The Main Types
- Numbers — like 7 or 3.14.
- Strings — words and letters in quotes, like "Hello".
- Booleans — only two values:
trueorfalse. - Lists — many things in order, like ["apple","banana","cherry"].
Why Does This Matter?
You can add two numbers (7 + 3 = 10), but you can't really "add" the booleans true + false. The type tells the computer what makes sense.
🎯
Try this!
Now you try! What type would you use for: your age? your name? whether you like pizza?

For grown-ups
Parent/teacher tip: Concrete examples help — money is a number, addresses are strings, "is it raining?" is a boolean.
