Introduction to Scratch

The Interface

This is the stage. This is where all the action will happen.

This is the sprite. Sprites are the actors in your

program. You can change how they

look and what costumes they wear.

Some of the Sprites

Each of these buttons has a list of different instructions

you can choose.

The list of instructions will appear here.

You will drag the instructions here to tell your sprite what

to do.

You can assign commands/instructions to

different items in your program. You select them

here.

This area is all to do with the sprites. This

is where you will select your sprite and tell it what to

do.

You can add new sprites, edit your sprites and get a

surprise sprite here.

The Stage

This is the X axisThis is the Y axis

If you hold your mouse over the stage this will tell you the coordinates of where the mouse is.

This centre point is X: 0, Y: 0.

This top left point is X: -240, Y: 180.

This bottom right point is X: 240,

Y: -180.

Some of the basics Use this control to start the program.

This is the control that will allow your sprite to move. You can change the bit in white to what ever number you want.

This control will make your sprite wait where he is.

Use this to stop the program.

Lets get started Can you get your sprite to walk from one

side of the screen to the other?

gets to one side and then get him to walk back again?

Can you get him to repeat this 5 times? Hint
