Transitioning from visual block coding to typed programming syntax, strict language rules, and text-based program execution.
Step 1: Code Typing
Recognise that text code consists of typed letters, numbers, and symbols requiring precise keyboard entry.
Let's Go!
Routine: See-Think-Wonder
Compare a Scratch block with a line of typed Python code. What looks identical and what looks different?
Teacher note: Facilitate the See-Think-Wonder routine for 2–3 minutes. Encourage students to connect the prompt to Form (Written symbols and structured rules allow humans to communicate precise instructions to computers.).
Learn
Text-based coding uses typed words and punctuation instead of drag-and-drop blocks. Computers require exact spelling and matching symbols to execute instructions. In computing, written symbols and structured rules allow humans to communicate precise instructions to computers. As you explore the interactive Python Console Simulator below, focus on how to type text code statements without missing letters or quotes.

Step 2: Syntax Rules
Follow strict syntax rules including capitalization, parentheses, and quotes when typing code statements.
Learning objective

Let's Go!
Routine: Think-Pair-Share
Look at print('Hello') vs PRINT[Hello]. Why will only one of these work in Python?
Teacher note: Facilitate the Think-Pair-Share routine for 2–3 minutes. Encourage students to connect the prompt to Function (Computer languages rely on strict syntax structures to interpret human logic consistently.).
Learn
Syntax is the grammar of programming languages. In Python, function names are case-sensitive, arguments sit inside parentheses (), and text strings must be enclosed in quotation marks. In computing, computer languages rely on strict syntax structures to interpret human logic consistently. As you explore the interactive Python Console Simulator below, focus on how to write syntactically correct output statements using proper punctuation.

Routine: Predict & Verify
If line 1 says print('Step A') and line 2 says print('Step B'), what prints first?
What happens if we swap them?
Teacher note: Facilitate the Predict & Verify routine for 2–3 minutes. Encourage students to connect the prompt to Change (Sequential code execution creates predictable outcomes in automated story narratives and calculations.).
Learn
Text programs execute line by line, starting at line 1 and moving downward. Changing the order of lines changes the sequence of output actions. In computing, sequential code execution creates predictable outcomes in automated story narratives and calculations. As you explore the interactive Python Console Simulator below, focus on how to predict exact output sequence of complex multi-line text programs.

Step 4: Variables & Input
Store, manipulate, and format typed text variables and interactive user inputs.
Learning objective
Students learn to create text variables, collect user inputs with input(), and output formatted responses.
Let's Go!
Routine: Connect-Extend-Challenge
How does a website remember your name after you log in?
How can a single line of text code do the same?
Teacher note: Facilitate the Connect-Extend-Challenge routine for 2–3 minutes. Encourage students to connect the prompt to Connection (Storing dynamic information in variables enables personalized and interactive computer programs.).
Learn
Variables store values using an assignment operator (=), like name = 'Alex'. The input() function asks the user a question and saves their typed response into a variable for later use. In computing, storing dynamic information in variables enables personalized and interactive computer programs. As you explore the interactive Python Console Simulator below, focus on how to format string concatenation and f-strings to display dynamic personalized outputs.

Step 5: Conditionals & Indent
Write structured if/else conditional statements using comparative operators and strict block indentation.
Learning objective
Students write text-based if/elif/else statements using comparison operators (==, >, <) and 4-space indentation.
Let's Go!
Routine: 4 Cs (Connections, Concepts, Changes, Challenges)
How does a video game check if you have enough points to open a door?
How do we write that check in text code?
Teacher note: Facilitate the 4 Cs (Connections, Concepts, Changes, Challenges) routine for 2–3 minutes. Encourage students to connect the prompt to Perspective (Conditional structures allow text programs to make dynamic decisions based on varying criteria.).
Learn
Text-based decisions use if, elif, and else keywords followed by a colon (:). Code inside each decision branch MUST be indented (typically 4 spaces) to show it belongs to that branch. In computing, conditional structures allow text programs to make dynamic decisions based on varying criteria. As you explore the interactive Python Console Simulator below, focus on how to write conditional text programs using dynamic comparison conditions.
