Scratch: Code You Can Slide
Scratch is a block-based coding language. Instead of typing code, you drag and snap coloured blocks together to build games and animations.
The three areas: the Stage (top right, where your project runs), the Sprites list (bottom right) and the Blocks Palette (left) where you pick blocks by colour.
Your First Program
- Open Block Studio or the Scratch editor.
- Pick the cat sprite (or add your own).
- From yellow Events, drag
when ▼ clickedonto the script area. - From blue Motion, snap
move 10 stepsbelow it. - Click the green flag and watch the sprite move!
Block Categories and Colours
- Motion — move, turn, go to positions
- Looks — say, think, change costumes
- Events — start scripts (green flag, keys)
- Control — wait, repeat, forever, if
- Sound — play sounds and music
Challenge
Make the cat say "Hello!" when you click the green flag. Then add two blocks that move it across the stage.
