Learn SCRATCH with Real Code Examples

Scratch uses visual blocks instead of written code.

Users combine blocks to build logic, animations, and games.

Ideal for beginners with no programming background.

Browser-based environment with a strong community.

Supports sprites, events, loops, variables, and sounds.

Motion, Looks, Sound, Events, Control blocks

Variables and lists

Broadcasting messages

Cloning sprites

Extensions like music, video sensing, and micro:bit

Blocks instead of text code

Sprites representing characters

Stage representing background

Events trigger behavior

Loops and conditions control logic

Sprites/ - characters with behaviors

Scripts/ - blocks attached to sprites

Costumes/ - sprite visuals

Sounds/ - audio assets

Stage/ - background and global events

Select or create sprites

Drag blocks into the scripting area

Combine blocks into scripts

Test and adjust behavior
