Lesson Topic: interpretation of simple inventory control charts
Learning Objective/s:
  • Describe the components of a simple inventory control chart.
  • Interpret chart data to identify current stock level, reorder point, and lead time.
  • Calculate EOQ and reorder point using given data.
  • Apply chart interpretation to make short‑term ordering decisions.
  • Evaluate common pitfalls and adjust the chart accordingly.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed handouts of a sample inventory control chart
  • Worksheet with EOQ and ROP calculations
  • Calculators
  • Markers and whiteboard
  • Sticky notes for quick checks
 Introduction:
Begin with a quick question: “What happens when a store runs out of a popular product?” Connect this to students’ prior experience with stock‑outs in everyday shopping. Explain that today they will learn to read inventory control charts and use them to decide when and how much to order, with success measured by correctly interpreting a chart and calculating EOQ and ROP.
Lesson Structure:
  1. Do‑now (5'): Students answer a short quiz on basic inventory terms.
  2. Mini‑lecture (10'): Explain chart components using a projected diagram.
  3. Guided practice (12'): Walk through interpreting a sample chart step‑by‑step.
  4. Calculation activity (15'): Students compute EOQ and ROP from provided data on the worksheet.
  5. Group simulation (10'): Teams role‑play ordering decisions based on chart updates.
  6. Check for understanding (8'): Quick exit ticket with two short questions.
Conclusion:
Summarise how reading the chart informs ordering timing and quantity, reinforcing the link between EOQ, safety stock, and reorder point. Students complete an exit ticket summarising one key insight and answer a short problem. For homework, they will locate a real‑world inventory chart online and write a brief analysis.
