What is Scratch?
• Scratch is a free programmable toolkit that
enables kids to create their own games,
interactive art, and animated stories.
• Scratch can allow users share their creations
and innovations via internet.

What is Scratch?
• Scratch is the world's largest coding community
and coding language for kids with a simple visual
interface that allows young people to create
digital stories, games and animations.
• Scratch is designed, developed and overseen by
the Scratch Foundation, a non-profit organization.
Scratch promotes computational thinking and
problem-solving skills; creative teaching and
learning; self-expression and collaboration; and
equity in computing.

What is Scratch?
• The essential goal of scratch is support kids
become fluent with digital media to draw
their ideas powerful.
• Scratch has many capabilities and
componential ideas to be easier for kids and
help them in starting programming and
graphics programs

Introduction of Scratch
• Scratch has become the world's largest coding community for
kids.
• In 2022, Scratch reached more than 100 million registered
users.
• Scratch launched in May of 2007 as a downloadable desktop
application.

Graphics Functions in Scratch
1. Create Background
• User can draw Scratch background or change
background properties as color, size, front/back layer.

2. Create Sprite
• Open the folders for the various sprites categories, by double
clicking on the appropriate one in a library of scratch has many
sprites in a program to make the experiment with it.
• In the animation, you may utilize more than one sprite.
• In addition, any user can draw his own graphical sprite

• User makes resizing sprite images or parts of images icons to
be smaller or larger by clicking on the dimensions of icons.

4. Dealing with Pixel
• A pixel:
– is considered a tiny component that makes up a
picture on a computer or television screen is a
pixel.
– is created through the combination of the words
image and element.

• Scratch coding is a visual programming language in which you
have to drag and drop blocks of code and attach them in a way
user connects a jigsaw puzzle.
• Scratch is a free educational website developed by MIT that
provides a great way to learn to code early.
26

• User can make drag and drop or left double click on block to
apply the animation on workspace.
• There is a presentation button to convert the vision into
presentation mode, and cancel it with press Esc button

- Control
• Control is:
– the following programming buttons category:
– this is very significant category due to detect number of
times an event happens (how many, how long of happened
event, when time of happed event).
– is a conditional statements are mutually entitled "if
statements: or "if-else" statements
