i + UNDERSTANDING BLOCKS
Blocks are puzzle piece shaped units that are used to give instructions to the computer. They are of
different colours, shapes and sizes. Each block represents a specific function, action, or command.
To code in Scratch, you drag and drop blocks into the Coding Area to place them together and
create a program. A collection of inter-locked blocks, called script makes a code in Scratch. When
you double-click on the script, Scratch runs the blocks from top to bottom. To use a block, simply
select it and then drag it onto the scripts pane. To remove a block from a script, just drag it to the
left where the blocks are present, away from the scripts pane.
Some of the categories of blocks are Motion, Looks, Sound, Events, Control, Sensing,
Operators, and Pen.
Block category Use
These blocks are used to control the movements of your Sprites.
Motion
These blocks control what your Sprites and backdrop look like.
Looks
These blocks are used to play or stop sounds.
Sound
These blocks are fundamental blocks. Each script has an event at its start
Events which tells the script to run.
These blocks control the blocks within your scripts, inserting conditional
Control statements, loops, repeats and pauses.
