Checkpoint & Reflection
45 minutes
Lesson Overview
Lesson Focus
Sprint retrospective and concept mastery assessment
Key Unit Objectives
Enduring Understandings:
- Inventory valuation methods directly impact reported profits, tax obligations, and business decision-making
- FIFO, LIFO, Weighted Average, and Specific Identification produce different COGS and ending inventory values
- Accurate inventory tracking is essential for business sustainability and investor confidence
- The inventory equation (Beginning Inventory + Purchases − COGS = Ending Inventory) must always reconcile
Lesson Activities
