* Daily materials

== Teaching Learning Activities ==

# Introduce today's topic with students.
# I will discuss previous topic.
# I will explain the step with example to convert (5674)<sub>10</sub>=(?)16
## Divide the given number system by 16.
## Write the quotient under the number. This number becomes the new number
## write the remainder on right side. 
## Repeat steps (a) to (c) until 0 is produced as the new number.
## The 1's and 0's written as the remainder in reverse order. (i.e. button to top) is the required binary number.
#I will show conversion steps hexadecimal number system to decimal number system using example.
## Write the binary digits as a power of 16 increasing from right to left starting from 0.
## convert each power of 16 into its decimal equivalent term.
## add all these to give the decimal numbers.
## I will convert (4ABC)16=(?)10.

== Classroom Assessment ==
