KS3 Flowol Lesson 2 – Flowchart Decisions & Self-Marking Quizzes

KS3 Computer Science – Flowol Flowchart Decisions & Control Systems
Fully Resourced Lesson | Includes FREE Self-Marking Quizzes & Teacher Tracking

A fully resourced KS3 Computer Science lesson focusing on Flowol flowchart symbols and decision-making within control systems.

UPDATED for 2026: This lesson now includes FREE online self-marking quizzes. Students receive instant feedback as they work, while teachers can track results and progress — ideal for AFL, homework, cover lessons, and mixed-ability pacing.

The lesson develops confidence with flowchart logic and decision diamonds, building essential foundations for algorithms, selection, and control at KS3 and GCSE.

What’s Included:

• Fully editable lesson resources (PowerPoint / Word-friendly)
• FREE online self-marking quizzes with instant student feedback
• Teacher tracking of quiz results and understanding
• Clear lesson structure with built-in assessment checkpoints

Lesson Activities:

• Starter literacy task introducing key vocabulary such as “simulate” and “flowchart”
• Explicit teaching of the four key flowchart symbols:
  • Terminator (start / end)
  • Process block
  • Decision (diamond)
  • Loop
• Step-by-step Flowol activities, including creating a working lighthouse simulation using process and decision blocks
• Guided analysis of real decision diamonds and their role in controlling automated systems
• “Is it OK to move on?” checkpoints embedded throughout to support self-assessment and pacing
• Challenge tasks where pupils modify Flowol programs to respond differently based on sensor inputs (e.g. sun on / sun off)
• Screenshot evidence tasks to support digital skills and assessment
• Creative extension: pupils design their own flowchart using decision diamonds to consolidate understanding

Learning Objectives:

• Understand and use the decision (diamond) symbol in flowcharts
• Create decision-based Flowol programs
• Explain how control systems automate repetitive or monotonous tasks
• Develop logical thinking and problem-solving skills

Why Teachers Choose This Lesson:

• No-prep and classroom-ready
• FREE self-marking quizzes reduce marking workload
• Teacher tracking supports quick intervention and AFL
• Strong scaffolding for mixed-ability classes
• Fully suitable for non-specialists with clear, step-by-step guidance
• Excellent progression towards GCSE algorithms and selection

Perfect For:

• KS3 Computing / Computer Science
• Flowol units and control systems topics
• Foundation work before GCSE algorithms and programming
• Cover lessons, homework, or retrieval practice
