Teaching Learning Activities

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