1. Motivation:

Who among you are members of the student council? As a member what do you usually do to help your co-students in school?

2.Presentation

Strategy: Use a problem Opener.

The school helpers are setting up the auditorium for the students council meeting. There are a total of 197 mono-block chairs which they have to set up in either rows of 3, 6 or 9 which are set ups.

1.Ask the student: What are given? What is being asked? How may we solve the problem?

2.Ask the student: If you were one of those who have to set up the auditorium, What would you do?

3.Have students solve the problem by actual division.

4.Tell the students that using the divisibility rules will help in identifying if a number is divisible by another number without actual division.


Put a check under the correct column applying the rules for divisibility.
