Content :
Meaning of money.
Money is a legal to tender which is generally accepted as a means of exchange for goods and services.
In Nigeria, the currency used is Naira and kobo. We have two denominations of currencies. These are notes and coins.
a.) Notes : The naira notes are made with papers with portraits. It has eight denominations, which are : #5.00, #10.00, #20.00, #50.00, #100. 00, #200.00, #500. 00, and #1000.00 respectively.
b.) Coins : The coins are made from metal materials. It ranges from kobo to one naira. Examples are : 5k, 10k, 20k, 50k, #1.00, #2. 00.
The symbol for naira (N) and kobo (k).
100k = # 100
Converting from Naira to Kobo.
When changing from naira to kobo, we multiply by 100.
For examples :
1. # 2.30 = 2.30 x 100 = 230k
2. #6. 15 = 6.15 x 100 = 615k
3. #15. 70 = 15. 70 x 100 = 1570
Exercise
Convert the following to kobo.
1. # 3. 25
2. # 7. 50 =
3. # 5. 43 =
4. #13. 20 =
5. #27. 95 =
6. # 154. 08 =
Changing or Converting Kobo to Naira
When changing kobo to naira we divide the given amount by 100.
Examples :
1. 520k = 520/100 =#5. 20k
2. 890k = 890/ 100 = #8. 90k
Exercises
Convert the following to naira.
1. 750k =
2. 430k =
3. 970k =
4. 1008k =
Presentation Steps :
Step 1 : The teacher revises the previous lesson with the learners by asking them questions.
Step 2 : Introduces the new topic by asking the learners to define money. He then gives a simple definition of money.
Step 3 : He asks them to identify the currency spent in Nigeria, and the denominations
Step 4 : Explains the relationship between the unit of money
Step 5 : Explains the principle of converting from one unit to another.
Evaluation :
Gives the learners some tasks to do in their Mathematics textbook as follows :
Convert the following kobo to naira
1. 350k =
2. 1520k =
3. 1700k =
4. 2640k =
5. 675k =
6. 12000k =
7. 37840k =
8. 28500k =
Convert the following from Naira to Kobo.
1. # 4.60 =
2. #3.00 =
3. #7. 08 =
4. #15.90 =
5. #63.15 =
6. # 128.10 =
7. # 200.38 =
Conclusion : At the end of the lesson learners were able to answer the questions correctly. He makes corrections where necessary and marks their notebooks.
