2. Two ₦5 + two ₦2 =

3. Two ₦2 + one ₦1 =

Pupil’s Activities

1. Two ₦5 + Ten ₦2

= ₦5 + ₦5 + ₦2 + ₦2 + ₦2 + ₦2 + ₦2 + ₦2 + ₦2 + ₦2 + ₦2 + ₦2

= ₦20

2. Two ₦5 + two ₦2

= ₦5 + ₦5 + ₦2 + ₦2

= ₦14

3. Two ₦2 + one ₦1

= ₦2 + ₦2 + ₦1

= ₦5

Pupil’s Exercises/Assignments – keep on engaging the pupils in the same units.

## LESSON TWO – NAIRA AND KOBO

Teacher’s comments – Naira is the not the only Nigerian currency. Kobo is parts of our currencies. We spend both Naira and Kobo. Two 50 Kobo (2 x 50 kobo) gives us ₦1.

Pupil’s Activities – Addition and Subtraction of Naira and Kobo (100 kobo or two 50 kobo = ₦1)

Teacher’s Activities

1. Add two 50 kobo and two ₦10

2. What is two ₦10 minus two ₦2?

3. What is five 1 kobo plus hundred 1 kobo?

Pupil’s Activities

1. Two 50 kobo + two ₦10

= 50 kobo + 50 kobo + ₦10 + ₦10

= 100 kobo + ₦20

= ₦1 + ₦20

= ₦21.

2. Two ₦10 – two ₦2

= ₦10 + ₦10 – (₦2 + ₦2 = ₦4)

= ₦20 – ₦4

= ₦16.

3. five 1 kobo + hundred 1 kobo?

= 5 kobo + 100 kobo

= 5 kobo + ₦1

= ₦1 50 kobo or ₦1.5
