BLOCKS IN SCRATCH

Blocks in Scratch are like jigsaw puzzle pieces. They connect vertically to create code. Each
block has a unique shape and slot. Simply drag them into the coding area to build a script.

Motion Blocks

Motion blocks let you control a sprite's movement on the stage, allowing it to move, turn and

change direction. They are blue in colour.

Some basic motion blocks used in Scratch and their descriptions are as follows:

This block makes the sprite move forward and backward,
allowing it to travel in both directions.

move 10 steps For example: Move 10 steps moves the sprite forward by
10 steps or Move -10 steps moves the sprite backward by
10 steps.

This block makes the sprite turn to the right (clockwise),
turn 15 degrees
rotating in a circle.

This block makes the sprite turn to the left
turn 15 degrees
(anticlockwise), rotating in the opposite direction.

Events Blocks

Events blocks run the script on the stage and control the start of scripts. Without an Events
block, no program will run. They are light yellow in colour.

Some of the commonly used Event Blocks with their description are as follows:

This block starts the script when the green flag is clicked.
when clicked
It is used to begin a project.

This block starts the script when a chosen key on the
when space key pressed
keyboard is pressed.

This block runs the script when the sprite is clicked.
