In the last lesson we looked at how computers repeat a sequence of instructions. Something that programmers more commonly call a loop.

Now we want to look at a extension of the loop pattern to show you a quick way to loop a fixed number of times.

To learn that repetition is more commonly called a loop.

To learn the different types of loops; to introduce the pattern for a loop that repeats while a condition is true.

The class will practice loops by adapting the previous 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 statement in Go.

Section: Lessons  

What You are Going to Learn

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.

Keyboard Input

Published on: Thu, Apr 2, 2015

Section: Teacher Notes  

Objective

To learn how to use variables to read input from the keyboard.

The class will learn one pattern for reading strings and numbers that have been typed at the keyboard by the user.

The class will then practice these patterns with the hellostranger 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.

Section: Lessons  

What You are Going to Learn

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.

More Variables

Published on: Wed, Apr 1, 2015

Section: Teacher Notes  

Objective

To practice using the patterns for integer and string type variables in Go.

The objective is to get the class to write a Go program that use variables.

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.

Section: Lessons  

What You are Going to Learn

In the last two lessons we introduced variables. Now we are going to put variables to work.

In this lesson we are going to show you how to use variables to remember what you have typed at the keyboard. We will introduce the pattern for going this.

Variables

Published on: Tue, Mar 31, 2015

Section: Teacher Notes  

Objective

The objective is to introduce the concept of a variable to the class.

The objective is to get the class to write a Go program to print strings to the terminal using the two different approaches that Go provides.

Creating this 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.

More Variables

You are going to practice declaring and assigning values to variables in this lesson. This will help you learn the patterns for variable declaration and variable assignment.

Further Words

Published on: Wed, Mar 25, 2015

Section: Teacher Notes  

Objective

The objective is to reinforce the classes knowledge of strings and how they are printed in Go. This is achieved by correcting a program that will not run. This is used to introduce the concept of a syntax errors. Syntax errors are a prelude to debugging.

The example program will again 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.

Words

Section: Teacher Notes  

Objective

The objective is to get the class to write a Go program to print strings to the terminal.

Creating this 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.

Variables

Published on: Wed, Mar 25, 2015

Section: Lessons  

What You are Going to Learn

In this lesson we are going to introduce variables. Computer programs use variables to remember things. Think of a word processor. The computer has to remember the words that you type. The word processor program uses variables for this.

We are going to show you the rules for variables and the patterns you need to use them in your programs.

Section: Lessons  

What You are Going to Learn?

In the last lesson you learned what a string was and the pattern that all strings must follow in Go.

In this lesson you are going to practice fixing some mistakes in programs that use strings. You will also learn an approach to fixing syntax errors.

Words

More Numbers

Published on: Tue, Mar 17, 2015

Section: Teacher Notes  

Objective

The objective is to reinforce the class knowledge of numbers and simple sums in Go and to reinforce the skills needed to create and run a Go program.

The pupils are introduced to brackets and shown how to use them to group terms. The pupils are also introduced to the idea of operator precedence.

Creating this 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.

Numbers

Published on: Tue, Mar 17, 2015

Section: Teacher Notes  

Objective

The objective is to get the class to write a Go program to solve simple mathematical problems. The program will only use addition (typed +), subtraction (typed -), multiplication (typed * not ×) and division (typed / not \ or ÷). Creating this 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.

Each subsequent lesson will require the class to use both the text editor and the terminal.

More Numbers

What You are Going to Learn

You saw in the last lesson how to do simple sums using Go. Now we want to show you that sums in Go follow the same mathematical rules that you already understand.

Maths is a universal language, even for computers.

Lastly we are going to show you the pattern you need to print a sum and its answer to the screen.

What You are Going to Learn?

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.
