To extend the pupil’s knowledge of if
selection statements by
introducing the closely related if else

The lesson also introduces the concepts of boolean, negation and not equals to.
The class will learn the pattern for an if else
statement in Go.
The class will practice using an if else
statement and see the effect
with the timesquestion
program.
Creating these program will require the class to use the text editor (either Atom or LiteIDE) to create and save the source code file and the terminal/command line to run their program.
To learn what selection statements are and how to use them.
The class will learn that selection statements are how computer programs make decisions.
The class will learn the pattern for an if

The class will practice using an if
statement and see the effect with the

Creating these program will require the class to use the text editor (either Atom or LiteIDE) to create and save the source code file and the terminal/command line to run their program.
In the last lesson we introduced the concept of selection. Selection is how a computer program makes a decision.
In this lesson we want to extend the concept to selection to show you how a computer program can make a choice between two or more alternatives.
In the last lesson we introduced the concept of keyboard input and showed you how the input can be stored in a variable.
But what if you wanted the computer to make a decision, based on what you had typed? How do you do this?
In this lesson we are going to show you how you can tell a computer program to
make a decision. We will introduce the pattern for if
statements as selection
is more commonly known.
Computers are used to process data. All data is made up of numbers. Yes, really! Everything is just a bunch of numbers to a computer. These are the only things they understand.
We are going to explain how numbers are used in Go programs. Then we are going to show you how to do type sums in Go.
