**LESSON FOUR – QUANTITATIVE REASONING **

As stated in the quantitative books or textbooks.

**PRESENTATION**

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Guides pupils through division of whole numbers such as 20⁄5 or 20 by 5.

Pupil’s Activities – Divide whole numbers not exceeding 48 by 2, 3, 4, 5, 6.

3. Leads pupils to divide by grouping and repeated subtraction, using counters not exceeding 48.

Pupil’s Activities – Solve division problems by grouping and repeated subtractions.

**CONCLUSION**

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

**LESSON EVALUATION **

**Pupils to **divide whole numbers not exceeding 48 by 2, 3, 4, 5 and 6 by grouping and repeated subtractions.
