Lesson Content/Board Summary

Money

The Concept of Kobo

Kobo is a unit of Nigerian currency, usually in coin form. It is a smaller unit compared to Naira.

The following are common kobo denominations:

• 50 kobo (50k)
• 25 kobo (25k)
• 10 kobo (10k)
• 5 kobo (5k)
• 1 kobo (1k)

NOTE: 100 kobo (100k) makes 1 Naira (N1).

Simple Addition of Money (Kobo)

Adding money means putting amounts together to find a total. We add kobo just like we add regular numbers.

Examples:

Example 1: Add 10k and 5k.

• Step 1: Write the numbers vertically: 10k
• Step 2: Add the kobo amounts: + 5k
• Step 3: Write the total: 15k

Example 2: Add 25k and 25k.

• Step 1: Write the numbers vertically: 25k
• Step 2: Add the kobo amounts: + 25k
• Step 3: Write the total: 50k

Simple Subtraction of Money (Kobo)

Subtracting money means taking one amount away from another to find the difference. We subtract kobo just like we subtract regular numbers.

Examples:

Example 1: Subtract 5k from 15k.

• Step 1: Write the numbers vertically: 15k
• Step 2: Subtract the kobo amounts: – 5k
• Step 3: Write the remainder: 10k

Example 2: Subtract 10k from 50k.

• Step 1: Write the numbers vertically: 50k
• Step 2: Subtract the kobo amounts: – 10k
• Step 3: Write the remainder: 40k

Lesson Keywords

• Money – What we use to buy things.
• Kobo – A small unit of Nigerian money.
• Denominations – Different values of money, like 50k or 10k.
• Addition – Putting numbers or amounts together.
• Subtraction – Taking one number or amount away from another.

Differentiation

For struggling learners, the teacher will use more visual aids and real kobo coins for hands-on practice, focusing only on 1k, 5k, and 10k. For advanced learners, the teacher will introduce slightly more complex addition and subtraction problems, perhaps involving three kobo amounts or sums up to 100k.

Note for teachers using this lesson plan

Ensure that real kobo coins or clear pictures are available for pupils to see and touch, as this aids concrete understanding for Primary 1 pupils. Keep the addition and subtraction problems very simple and within the pupils’ counting range to build confidence. Encourage pupils to use simple counting strategies to solve problems.
