KS3 Computer Science – Flowol Flowchart Decisions & Control Systems (2026 Updated)
Fully Resourced Lesson | Includes FREE Self-Marking Quizzes & Teacher Tracking
A fully resourced KS3 Computer Science lesson focused on Flowol flowchart symbols and decision-making within control systems.
Updated for 2026: Now includes FREE online self-marking quizzes. Students receive instant feedback while teachers can track results and progress — ideal for AFL, homework, cover lessons and mixed-ability pacing.
This lesson builds confidence with flowchart logic and decision diamonds, establishing strong foundations for algorithms, selection and control at KS3 and GCSE level.
What’s Included:
- Fully editable lesson resources (PowerPoint / Word-friendly)
- FREE online self-marking quizzes with instant feedback
- Teacher tracking of results and understanding
- Clear lesson structure with built-in assessment checkpoints
- Screenshot evidence prompts for assessment or digital portfolios
Lesson Activities:
-
Starter literacy task introducing key vocabulary such as “simulate” and “flowchart”
-
Explicit teaching of four key flowchart symbols:
- Terminator (start / end)
- Process block
- Decision (diamond)
- Loop
-
Step-by-step Flowol activities including building a working lighthouse simulation using process and decision blocks
-
Guided analysis of decision diamonds and their role in controlling automated systems
-
“Is it OK to move on?” checkpoints throughout to support self-assessment and pacing
-
Challenge tasks where students modify programs to respond differently to sensor inputs (e.g. sun on / sun off)
-
Screenshot evidence tasks to support digital skills and assessment
