CLASS: Primary 6
DATE: ____________________
PERIOD: ____________________
DURATION: 40 minutes

LEARNING OBJECTIVES:

By the end of the lesson, pupils should be able to:

1. Identify parts of the Scratch interface.
2. Differentiate between the 3 S’s of Scratch.

KEY VOCABULARY WORDS:

Scratch, Sprite, Stage, Script, Blocks

INSTRUCTIONAL MATERIALS:

• Computer system with Scratch installed
• Projector or screenshots of Scratch interface

INTRODUCTORY ACTIVITY:

The teacher asks: “Have you ever made a cartoon character move on a computer? Scratch allows us to do that.”

CONTENT OF THE LESSON:

What is Scratch?

Scratch is a fun and easy programming language made especially for children. It helps pupils create animations, games, and stories by putting together blocks of instructions — like building with Lego!

With Scratch, you don’t need to type long codes. You just drag and drop colorful blocks to make things happen.

The 3 S’s of Scratch

1. Sprite

A Sprite is a character or object in Scratch.

Example: The cat you see when you open Scratch is a Sprite.

You can add new Sprites like people, animals, cars, etc.

1. Stage

The Stage is the background where your Sprites perform.

It’s like the scene in a play or movie.

1. Script

A Script is the set of instructions you give to a Sprite.

It tells the Sprite what to do, like move, talk, or dance.

Components of the Scratch Interface

When you open Scratch, you’ll see different parts on the screen. Here are the main ones:

1. Blocks Palette

This is where all the coding blocks are found.

Blocks are grouped by color and action (motion, looks, sound, etc.).

1. Scripting Area

This is where you drag and join blocks to build your Script.

It’s like your workspace where you write your code.

1. Stage Area

This is where you see the action!

You can watch your Sprite move, talk, or perform on the Stage.

1. Sprite List

This shows all the Sprites in your project.

You can click on each one to edit their scripts or looks.

Conclusion

Scratch is a creative and fun way to learn coding. You can build your own stories, games, and animations just by joining blocks! It helps pupils think, plan, and solve problems in a fun way.

CLASS EXERCISE 1:

Define Sprite, Stage, and Script in Scratch.

CLASS EXERCISE 2:

Draw and label the parts of the Scratch interface.
