• Basic input and output commands
• Variables to store temporary input
• Legal and illegal names

Activites Programming in interactive mode Bits
of code with errors to be fixed Data
Types Reseach languages

Lesson 2 Flowcharts, sequencing and simple
decisions

• Flow charts
• Using IF statements
• Create Password testing program

Activities Cup of tea card sort True/False quiz
question in interactive mode

Lesson 3 Prototyping a Hangman game

• Introduce hangman project
• Indentify buiding blocks of game
•  Adapt password testing program

• Activites
• Determine rules by playing the game

Lesson 4 Repeating and looping actions

• Loop
• For loop
• While loop
• Indenting code to control code

Activities Make text for 10, 20 green botles
song Scenarios given for students to indentify
loops Homework write simple program with
loops to navigate maze

Lesson 5 Using functions to develop a better
game

• Importing functions from modules
• Concept of toolbox functions
• Lists

Acitvities Using Math, String Random
modules Using toolbox functions Lists to store
multiple values
11
Lesson 6 Testing the final prototype

• Test the game
• ASCII art
• Improve final version to select random word

Activities Design hangman graphics Use test plan
