BLOCKS

Blocks are the codes or commands used to create a program in Scratch. It looks like a puzzle
piece and each block connects with the other block to perform a task.

Motion Block

The blocks that are used to control the movement of a sprite are known as Motion blocks.
They are blue in colour. For example, the motion block is used to move a sprite.

Here, 10 is the number of steps that the sprite will move forward move 10 steps . You can change
the number of steps. To make the sprite move backward, give a minus (–) sign before the

number as shown move -30 steps . This will move the sprite 30 steps back on the stage.

Looks Block

The blocks that are used to add speech and thought bubbles to the sprite are called Looks

Block. They are purple in colour.
For example, you want to add a speech bubble to the sprite for 2 seconds with a message

‘Hello!’ as shown say Hello! for 2 seconds .

You can change the message by clicking on the message text box and typing your own
message. You can also change the time by clicking on the time text box. think Hmm... for 2 seconds
