Introduction to Scratch

• Scratch is an easy and enjoyable programming language.
• It assists students in making games, stories, and animations as they assemble colourful blocks.
• You will not have to enter challenging codes.
• You would rather drag and drop blocks to make your program work.
• Scratch is user-friendly and fun to use, as it is aimed at beginners.

What is Scratch?

Scratch is a visual programming language.

It allows students to:

• Create animations
• Design simple games
• Make interactive stories
• Add sound and music

Scratch assists in enhancing creative thinking and problem-solving

Main Parts of Scratch

The screen that opens when you open Scratch has various sections.

Stage

• Your project is executed on the stage.
• Here, the characters move, and the actions take place.

Sprite

• Scratch has sprites that are characters or objects.
• Sprites can be controlled through code blocks.

Coding Area

This is where you drag and combine blocks to form a program.

Blocks Palette

• Some blocks of different colours are found in this section.
• Every colour denotes a kind of action.

Types of Blocks

Scratch blocks are categorised as follows:

• Motion Blocks - Move sprites.
• Looks Blocks – Alternate appearance.
• Sound blocks – Add sound and music.
• Events Blocks - Start actions (e.g., when the green flag is clicked).
• Control Blocks – Repeat or control actions.

You mould these blocks into puzzle pieces.

Why Learn Scratch?

• It develops problem-solving abilities.
• It improves creativity.
• It assists in learning simple programming.
• It simplifies the process of learning code.
