Lesson Plan
Grade: Date: 25/02/2026
Subject: Accounting
Lesson Topic: calculate sales, purchases, gross profit, trade receivables and trade payables and other figures from incomplete information
Learning Objective/s:
  • Apply key accounting equations to reconstruct missing figures in incomplete‑record problems.
  • Calculate sales, purchases, gross profit, trade receivables and trade payables from limited data.
  • Check accuracy by ensuring the reconstructed trial balance balances (debits = credits).
  • Explain common pitfalls and how to avoid them.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed worksheet with incomplete‑record problems
  • Calculator or spreadsheet software
  • Whiteboard and markers
  • Sample trial‑balance handout
  • Answer key for teacher
Introduction:
Small businesses often keep only partial records, leaving accountants to fill the gaps. Students already know the profit‑and‑loss statement, COGS and basic debtor/creditor equations, which they will now apply to incomplete data. By the end of the lesson they will be able to solve a full set of figures and verify the trial balance.
Lesson Structure:
  1. Do‑now (5') – quick recall quiz on profit‑and‑loss and COGS formulas.
  2. Mini‑lecture (10') – introduce incomplete records, key relationships and methodology.
  3. Guided practice (15') – work through Worked Example 1 together, step‑by‑step.
  4. Independent practice (15') – students solve a new incomplete‑record problem from the worksheet.
  5. Peer check (5') – compare answers, teacher circulates to address misconceptions.
  6. Whole‑class debrief (5') – discuss common pitfalls and confirm the trial balance balances.
Conclusion:
We recap the systematic approach: list knowns, apply equations, solve algebraically, and verify the trial balance. Students complete an exit ticket by writing one tip for avoiding errors in incomplete‑record calculations. For homework they finish a second practice set and bring any questions to the next lesson.
