Introduction to Coding

Overview

This 60-minute lesson is the 5th in the "Mastering Computer Basics" unit, designed for Year 7 students aged 11-12. It provides a carefully structured introduction to coding, highlighting its relevance and foundations in programming languages. The lesson aligns with the National Curriculum for England for Computing (Years 7-9), specifically focusing on Computational Thinking and Programming.

Learning Objectives

By the end of this lesson, students will be able to:

• Understand what coding is and why it is important in technology and daily life (NC computing key concept: Understanding computers and purpose of programs)
• Identify key features of programming languages and recognise simple syntax and commands (NC KS3 Computing: Design, write and debug programs)
• Explain how algorithms translate into code (NC KS3 Computing: Computational thinking)
• Create a basic program using block-based coding environment or simple text code (NC KS3 Computing: Programming)

National Curriculum References

• Key Stage 3 Programme of Study, Computing:

  • Design, use and evaluate computational abstractions that model the state and behaviour of real-world problems and physical systems
  • Use two or more programming languages, at least one of which is textual, to solve a variety of computational problems
  • Understand how instructions are stored and executed within a computer system
  • Work with variables, input, output, sequence, selection, and iteration

• In Relation to Key Stage 2 (for progression awareness):

  • Build on previous knowledge about algorithms to design, write and debug programs that accomplish specific goals.

Resources Required

• Laptop or desktop computer with internet access
• Block-based coding platform (e.g., Scratch or Microsoft MakeCode) or a text-based introduction (e.g., Python via an interactive platform like Trinket)
• Projector/screen for teacher demonstration
• Whiteboard and markers
• Printed worksheet with coding keywords and sample code snippets
• Student notebooks and pens

Lesson Structure

Starter (10 minutes)

• Engage: Begin by asking students, “What do you think coding is?” and “Where do you see computers using code in everyday life?”
• Capture their ideas on the whiteboard, linking their responses to everyday examples (smartphones, games, online apps).
• Present a short animated video or animation explaining what coding is and why it’s important (teacher-led, no link provided).
• Briefly explain that coding is the language that tells computers what to do.

Main Activity (40 minutes)

Part 1: Coding Concepts Introduction (15 minutes)

• Introduce basic programming concepts: commands, sequence, variables, loops, and conditions using simple, age-appropriate language.
• Use visual examples on the board or projector, e.g.:
  • Sequence: Step-by-step instructions like a recipe
  • Variable: A box that stores information
  • Loop: Repeating actions
  • Condition: “If...then...” statements
• Show simple code snippets in block format and equivalent text format to highlight their similarities and differences.

Part 2: Coding Demonstration and Guided Practice (25 minutes)

• Demonstrate a basic "Hello, World!" program and a simple sequence or loop in the chosen platform.
• Guide the student through replicating the program on their device.
• Extend by adding a variable or simple condition: e.g., user input that changes programme output.
• Encourage experimentation by changing commands or values to see different outcomes.

Plenary (10 minutes)

• Ask the student to explain in their own words:
  • What coding is
  • One example of how code is used in real life
  • The difference between sequence and loop
• Use a quick quiz or formative assessment: Identify whether a given snippet is a sequence, loop or condition.
• Discuss how this lesson prepares them for more complex programming challenges in the unit.

Differentiation

• For additional support: Use block-based coding exclusively; provide printed code snippets to follow step-by-step.
• For extension: Challenge the student to write a short pseudocode or attempt simple Python text code to replicate the block program.

---

Assessment and Feedback

• Informal assessment through observation and questioning during practical activity.
• Completed practical program saved or screenshot taken as evidence.
• Use the plenary quiz to quickly assess understanding.
• Provide verbal feedback immediately and identify areas to revisit in future lessons.

---

Cross-Curricular Links

• Maths: Understanding variables and sequences enhances logical thinking and problem-solving.
• English: Writing precise instructions improves literacy and communication skills.

---

Homework/Extension Task

• Task: Research and list three programming languages used in the real world and write one sentence on what each is used for.
• Optional: Create a simple flowchart (on paper) representing the steps to make a sandwich, linking it to algorithmic thinking.

---

Reflective Teacher Notes

• Ensure the student feels supported while experimenting with code — the trial-and-error process is vital.
• Use lots of praise for problem-solving steps, not just correctness.
• Bring real-world tech examples next lesson for continued engagement in programming foundations.

This lesson plan guarantees a meaningful start to coding for Year 7 students, firmly grounded in the National Curriculum expectations, and designed to inspire curiosity and confidence in programming fundamentals.
