This document introduces programming with Scratch, an integrated development environment (IDE) that uses visual blocks to construct code. It provides an overview of how computers follow instructions from programs. It then describes the Scratch IDE work areas and shows how to create a simple "hello world" program. It demonstrates building a ball and bat game in Scratch and modifying it by changing attributes like colors or rebound angle. The goal is to introduce the Scratch interface and develop an understanding of its tools by creating and modifying programs.

3. Overview
Computers follow instructions that programmers
create to perform a specific task
Programmers can either:
Hand code the programs
Use a Graphical Interface or an
integrated development environment
(IDE)

7. The hello World Program
First steps into programming we learn how to
create a simple hello world program

8. Recap
So to recap what we have learnt that:
Programmers have choices
About the Scratch interface
And we have created a
hello world program

9. Building a Game using Scratch
In this next section we are going to create a
game from scratch.
Bat and Ball

10. Can we Extend or modify the program
We now what to add additional features to our
game.
Spend about 7 mins to see if you can add
to the game.
• Maybe you want to change the colours
• Increase the angle of the rebound
---- > let your imagination decide

12. Summary
Introduced the Scratch IDE and developed
an understanding of the interface and
tools.
• Created a simple hello world program
• Replicated the bat and ball game
• Modify the bat and ball game to extend
its capabilities
