This document introduces programming concepts like sequencing and subroutines. It begins by comparing how humans and computers understand instructions and defines programming as how you get computers to solve problems. The key points are that computers follow instructions precisely in the order given, while sequencing means instructions are performed in order. Subroutines are blocks of code that perform a certain task and can be repeatedly used, making programs smaller and easier to read. Non-computing examples of sequencing and subroutines are discussed.

1. S1 PROGRAMMING
Lesson 1: Sequencing

2. StarterActivity
■ Can computers do the job of humans?
■ Are there jobs computers just cannot do instead of humans?
■ Are there jobs computers can do better than humans?

3. Learning Intentions
In this lesson, you will:
● Compare how humans and computers understand instructions
● Define what is programming
● Define a sequence
● Predict the outcome of a simple sequence
● Modify a sequence
● Key words – Sequencing, selection and iteration

5. What is programming?
“Programming is how you get computers to solve problems”
1. You:Without the programmer (you), the computer is useless. It does what you tell it
to do.
2. Solve problems: Computers are tools.They are given instructions to perform various
tasks.

6. Programming KeyWords - Sequencing
■ Instructions are preformed in order
■ As you have seen, computers will follow your
instructions precisely and in the order in
which you tell it.
■ Can you think of any non-computing
examples of where instructions need to be
carried out in the correct sequence?

7. Programming KeyWords - Subroutines
■ A sequence of program instructions that performs a certain task.
■ Are blocks of code that may be repeatedly.
■ Makes the layout of your program smaller and
easier to read.
■ Can you think of any non-computing
examples of where instructions need to be
carried out in a subroutine?

8. Sequence and SubroutineTask
■ Listen to the following song:
■ Now completeTask - Frère Jacques

9. PlenaryTask
■ What is smart but only if given the correct instructions?
■ What is the name for doing something over and over again?
■ What is required to make computers do there jobs?
■ What needs to be out into a certain order for your program to work?

10. SuccessCriteria
I can:
● Describe how humans and computers understand instructions
● Explain what programming is
● Explain the keywords sequencing and subroutine
● Create a simple Scratch program with subroutines
