SMASE – ASEI PDSI METHOD
TOPIC – L. C. M. AND H. C. F. OF NUMERALS NOT MORE 3 DIGITS
Lesson One – Least Common Multiples
Lesson Two – Highest Common Factors
Lesson Three – Least Common Multiple and Highest Common Factors
Lesson Four – Revision
Lesson Five – Test
TIME – 40 Minutes each.
By the end of the lesson, pupils should be able to:
1. find common factors of 2-digit whole numbers
2. find the HCF of 2-digit whole numbers.
3. find common multiples of 2-digit whole numbers
4. find the LCM of 2-digit whole numbers.
LCM stands for Lowest Common Multiple. HCF on the other hand, stands for Highest Common Factor. LCM and HCF are both used to minimize or maximize possible outcomes between two or more things.
The concept of LCM and HCF will enable people to understand and appreciate the importance of LCM and HCF in sharing or allocating two or more things among different groups with any conflict or waste.
The teacher will teach the lesson with the aid of charts of factors and multiples of numbers.
The pupils have the knowledge of multiplication of numbers up to 12 x 12.
