Geometry

The screen where you can see what happens when

you play your game is called the STAGE.

The SCRIPT BANK is where the types of instructions

are stored.

The SPRITES are where you store and select the STAGE and

COSTUMES

SCRIPTS AREA is where you put your instructions

The SCRIPT BLOCKS are where the

instructions of what your

SPRITES can do!
