Lesson Content/Board Summary

DOUBLE ENTRY AND THE THREE-COLUMN CASH BOOK

The Three-Column Cash Book (Further Treatment)

The three-column cash book includes columns for Cash, Bank, and Discount. It records cash and bank transactions, as well as discounts allowed and received.

Key aspects of the three-column cash book include:

Contra Entries: These are transactions that affect both the cash and bank columns of the cash book. They are marked with a ‘C’ in the folio column. Examples include cash deposited into the bank or cash withdrawn from the bank for office use.
Discount Allowed: This is a reduction in the amount owed by a customer for prompt payment. It is a loss to the business and appears on the debit side of the cash book.
Discount Received: This is a reduction in the amount owed to a supplier for prompt payment. It is a gain for the business and appears on the credit side of the cash book.

Meaning of Ledger

The ledger is the principal book of accounts in which all transactions are recorded in a summarized and classified form. It contains various accounts, each representing a specific asset, liability, equity, income, or expense. It shows the summarized effect of transactions on each account.

Types of Ledger Accounts

Ledger accounts are generally classified into three main types:

Personal Accounts: These accounts relate to individuals, firms, or companies with whom the business has dealings (e.g., Debtors, Creditors).
Real Accounts: These accounts relate to assets owned by the business (e.g., Cash, Bank, Furniture, Machinery, Land and Building).
Nominal Accounts: These accounts relate to expenses, losses, incomes, and gains (e.g., Salaries, Rent, Wages, Discount Allowed, Discount Received, Sales, Purchases).

Application of Double Entry from Cash Book to Ledger

The double entry system requires that every transaction has two aspects: a debit and a credit of equal value. When posting from the cash book to the ledger, the entries in the cash book are transferred to the relevant ledger accounts following the double entry principle.

For example:

Cash received from a debtor (Debit Cash in Cash Book, Credit Debtor’s Account in Ledger).
Payment made to a creditor by bank (Credit Bank in Cash Book, Debit Creditor’s Account in Ledger).
Discount allowed (Debit Discount Allowed Account in Ledger, Credit Debtor’s Account in Ledger).
Discount received (Credit Discount Received Account in Ledger, Debit Creditor’s Account in Ledger).

Posting Transactions to the Ledger

Posting is the process of transferring entries from the books of original entry (like the cash book) to the ledger accounts.

The steps for posting transactions to the ledger are:

Identify the two accounts affected by the transaction.
Determine which account is to be debited and which is to be credited.
Locate the relevant ledger account.
Enter the date, details (e.g., “Cash,” “Bank,” “Discount”), folio reference (e.g., “CB” for Cash Book), and amount on the appropriate side (debit or credit).
Ensure the corresponding entry is made in the other affected account.
Balance the accounts periodically to determine their closing balances.

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and reviews the previous lesson on the basic cash book. The teacher then asks pupils to recall the meaning of double entry and its importance in accounting.

Step 2: Presentation of the Three-Column Cash Book (Further Treatment)

Time: 10 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher uses a chart showing a three-column cash book format. The teacher explains and demonstrates how to record contra entries between cash and bank columns. The teacher also explains the nature of “Discount Allowed” and “Discount Received” and how they are recorded in the cash book’s discount columns, emphasizing that these columns are not balanced.
Pupils’ Activity: Pupils observe the chart, listen to the explanations, and ask questions for clarification.
Learning Point: Pupils understand contra entries and the role of discount columns in the three-column cash book.

Step 3: Definition and Types of Ledger Accounts

Time: 7 minutes

Step 4: Application of Double Entry from Cash Book to Ledger

Time: 8 minutes
Teaching Skill: Explanation/Illustration
Teacher’s Activity: The teacher explains the principle of double entry as it applies to posting from the cash book to the ledger.

Learning Point: Pupils grasp how the double entry principle is maintained when transferring information from the cash book to the ledger.

Step 5: Demonstration of Posting Transactions

Time: 7 minutes

For pupils who need more support, the teacher will provide additional guided practice, simplify examples, or pair them with stronger pupils for peer support during practical exercises.

Note for teachers using this lesson plan

Ensure that pupils have a strong foundation in basic double entry before proceeding with this lesson. Use clear, large charts for demonstrations to ensure visibility for all pupils. Encourage active participation and provide individual feedback during practical sessions. Emphasize the systematic nature of accounting and the importance of accuracy.
