more number.

Purpose (Basic Competency):
Students are able to:

1.   Calculate factors and multiples of a number
2.   List the factors and multiples of a number
3.   Give the examples of factors and multiples in daily life
4.   Identify prime and composite numbers
5.   Differentiate between prime and composite numbers
6.   List prime and composite numbers
7.   Calculate the prime factorization
8.   Decompose the composite number into prime factors
9.   Write index notation
10. Understand the Highest Common Factor (HCF) and Least Common Multiple (LCM) of two
or more number
11. Calculate the Highest Common Factor (HCF) and Least Common Multiple (LCM) of two or
more number
12. Give the examples of HCF and LCM in daily life

Skills:

Students are able to:

1.  Calculate factors and multiples of a number
2.  Differentiate prime numbers and composite number
3.  Understand the Highest Common Factor (HCF) and Least Common Multiple (LCM) of two
or more number
4.  Calculate the Highest Common Factor (HCF) and Least Common Multiple (LCM) of  two
or more number

Assessment:

1.  Worksheet
2.  Exercises assigned from workbook

Essential Questions:

•   What is the factors and the multiples?

•   How to find the factors and multiples of a number?
•   What is the usage of factors multiples in daily life?
•   What is the prime and the composite number?
•   How to differentiate the prime and the composite number?
•   What is the highest common factor (HCF) and the lowest common multiple (LCM)?
•   HCF and LCM in daily life.

Learning Activities:

A . Opening/Introduction:
Show the animation about the factor of a number in daily life
Write a number as a product of its factors.
Writes a number and its factors, and recognise which  prime or composite number is
Give another examples of the numbers which is prime or composite number
Writes a number and its factors, then identify its prime factors with the aid of factor tree or
other method
Gives the interactive worksheet about HCF to build students understanding about HCF

B. Main Activities:
Explains a number is divisible by its factors and the remainder is zero
Give the questions about factors and multiples by animation
Give the difference between factors and multiples of a number, by animation

Give the difference between prime or composite numbers,  by animation
Play a game in groups related to prime or composite numbers on interactive game
animation
Give the worksheet about factor and multiple to the students
Give the worksheet about prime factorization and index notation
it with animation

C. Closing:
Students will ask teacher about the materials that they do not understand
Summarize the lesson that just learned
