Lesson Plan

• Describe the purpose of depreciation and its impact on the balance sheet and profit‑and‑loss account.
• Calculate depreciation using straight‑line, reducing‑balance and units‑of‑production methods.
• Prepare the correct journal entry for depreciation and post it to the appropriate T‑accounts.
• Apply the exam checklist to produce a complete, accurate answer for depreciation questions.

• Projector and screen for slides
• Whiteboard and markers
• Printed worksheet with depreciation problems
• Calculator for each student
• Sample T‑account templates
• PowerPoint presentation covering methods and journal entries

Begin with a quick poll: “What happens to a delivery van after five years of use?” Connect this to students’ prior knowledge of asset costing and journal entries. Explain that today they will learn how to record depreciation so that the financial statements reflect the asset’s true value. Success will be measured by correctly completing a journal entry and posting it to T‑accounts.

1. Do‑now (5') – Short quiz on asset definitions and previous journal‑entry practice.
2. Mini‑lecture (10') – Why depreciation is recorded; overview of straight‑line, reducing‑balance and units‑of‑production methods with diagram.
3. Guided practice (15') – Walk through the van example: calculate straight‑line depreciation, write the journal entry, and fill in the worksheet.
4. Method comparison activity (10') – In pairs, calculate depreciation for a machine using reducing‑balance and units‑of‑production; discuss results.
5. T‑account posting (10') – Demonstrate posting the journal entry to Depreciation Expense and Accumulated Depreciation T‑accounts; students complete their own T‑accounts.
6. Check for understanding (5') – Exit ticket: write the journal entry for a given asset and state its net book value.

Recap the steps from calculating depreciation to posting the journal entry and updating T‑accounts. Collect the exit tickets to gauge mastery and assign homework: complete a worksheet that includes one straight‑line and one reducing‑balance problem, and prepare the corresponding ledger entries.
