__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

• Explains the concept of prime and composite numbers

• 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

• Ask the student about HCF and LCM concept, then the teacher explain more clearly about

it with animation
