All eight main block categories in Scratch 1.4.

Block categories are how blocks are organized in the Scratch editor. In Scratch 1.4, there were eight main block categories, as well as an extension:

Motion Blocks

Main article: Motion Blocks

These blocks control how sprites move. The stage has no motion blocks, as it cannot move.

Motor Blocks

Main article: Motor Blocks

These blocks control the LEGO WeDo Construction Set. They could be accessed in the "Edit" tab on the editor header. They were replaced by the LEGO WeDo 1.0 Extension.

Control Blocks

Main article: Control Blocks

These blocks control the flow of a project. They included many Hat Blocks to start scripts, as well as blocks to loop and pause scripts. In Scratch 2.0, they were split into Events Blocks.

Looks Blocks

Main article: Looks Blocks

These blocks control what a sprite looks like. For example, they can change costumes and show and hide a sprite.

Sensing Blocks

Main article: Sensing Blocks

These blocks let sprites sense other sprites and objects on the stage. For example, a sprite can sense if it is touching other sprites.

Sound Blocks

Main article: Sound Blocks

These blocks can play sounds. They can also play music using MIDI.

Operators Blocks

Main article: Operators Blocks

These blocks deal with mathematics, such as arithmetic, boolean values, and other functions.

Pen Blocks

Main article: Pen Blocks

These blocks use the pen to draw on the stage.

Variables Blocks

Main article: Variables Blocks

These blocks deal with variables and lists. They were organized in two sections: Variable and List.
