Lesson Plan

• Describe the hardware components and core functions of a POS terminal.
• Explain how a POS system automatically updates inventory records after a sale.
• Demonstrate how the system triggers a purchase order when stock falls below the re‑order point.
• Evaluate the benefits of automatic stock management for retail operations.

• Projector and screen
• POS simulation software or demo account
• Sample barcode images (printed)
• Printed handout of POS workflow and inventory sheet
• Worksheets for group activity
• Internet access for research

Start with the question, “How do stores know when to reorder stock?” Students recall previous lessons on manual inventory tracking. Explain that today they will explore POS terminals that link sales directly to inventory updates. Success criteria: students will describe POS components, trace the automatic update process, and illustrate how a re‑order is generated.

1. Do‑Now (5'): Students list ways a shop could track sales manually; share responses.
2. Mini‑lecture (10'): Introduce POS hardware and core functions using slides and a live demo of POS software.
3. Guided walkthrough (12'): Show the automatic stock‑update flowchart; students annotate the steps on their handout.
4. Group activity (15'): In small groups, simulate a sale with barcode images, update the inventory sheet, determine if a re‑order is needed, and create a mock purchase order.
5. Whole‑class debrief (8'): Groups present their purchase orders; teacher highlights correct trigger points and benefits.
6. Exit ticket (5'): Students write one sentence summarising how a POS system prevents stock‑outs.

Recap the POS workflow and its role in automatic stock management. Collect the exit tickets to check understanding. For homework, ask students to research a real‑world POS system and write a short paragraph describing its automatic ordering feature.
