Let’s learn about the some of the basic Components of Scratch Window

• Menu
• Stage
• Code Blocks/ Block Palette
• Program Sprites
• Coding Area

Menu Bar

The menu bar contain various project and sprite-related management tasks. These options are scratch logo, file menu, edit menu, tutorials. Explain all the function one by one.

Menu Name	Function

Stage

The Stage is where you see your stories, games, and animations come to life. Sprites move and interact with one another on the Stage. When Scratch Begins, It Has a Big Orange Cat middle of the stage.

The Stage is 480 units wide and 360 units tall. It is divided into an x-y grid. The middle of the Stage has an x- y coordinate (0, 0).

This means the lower left is at (-240, -180), the upper left is at (-240, 180), the upper right is at (240, 180), and the lower right at (240, -180). For example, the stage does not have motion or size blocks.

Now move the sprite to the bottom left corner of the stage where x -y coordinator (128, 81)

The Stage has several controls

• Green Flag: This flag is used to start the program or project.
• Red Stop Sign: This is used to stop the program or project
• Small stage – decrease the stage windows and increase the script area.
• Full stage – increase the stage windows and decrease the script area.
• Presentation mode – switch the stage window to full-screen.

• stamp – create a copy of an existing sprite.
• scissors – delete a sprite, costumes, sound or video
