Grade: Date: 17/01/2026
Subject: Accounting
Lesson Topic: duality
Learning Objective/s:
  • Describe the duality principle and its effect on the accounting equation.
  • Apply debit and credit rules to identify correct entries for assets, liabilities, equity, revenue, and expenses.
  • Record journal entries for simple transactions ensuring total debits equal total credits.
  • Analyse how each transaction maintains the balance of the accounting equation.
  • Identify and correct common mistakes related to double‑entry recording.
Materials Needed:
  • Projector or interactive whiteboard
  • Accounting textbook or printed handout on duality
  • Sample transaction worksheets
  • T‑account templates (paper or digital)
  • Calculator
  • Whiteboard markers
 Introduction:
Begin with a quick poll: Who can recall the accounting equation? Review that assets equal liabilities plus equity. Explain that today we will explore how every transaction respects this equation through the duality (double‑entry) principle. Success will be measured by correctly constructing journal entries and confirming the equation stays balanced.
Lesson Structure:
  1. Do‑now (5') – Students list the five account types and note whether a debit increases or decreases each; teacher circulates.
  2. Mini‑lecture (10') – Explain the duality principle and debit/credit rules using the provided table; illustrate with the cash‑service revenue example.
  3. Guided practice (12') – Work through the “Purchase of inventory on credit” example; pairs fill in T‑accounts and draft the journal entry.
  4. Independent practice (10') – Students complete a worksheet with three varied transactions, writing journal entries and checking the accounting equation.
  5. Check for understanding (8') – Quick quiz (Kahoot or exit ticket) where learners identify the correct debit or credit for given accounts.
  6. Review common errors (5') – Discuss the typical mistakes highlighted in the source and clarify misconceptions.
Conclusion:
Recap that the duality principle ensures the accounting equation remains balanced and that accurate debits and credits are essential. For the exit ticket, each student writes one key rule for debits and one for credits. Homework: complete the additional journal‑entry worksheet posted on the LMS.
