Teaching Learning Activities

1. Introduce today's topic with students.
2. Revise necessary topics required to learn previous topics.
3. I will explain Binary number system and decimal number system.
4. I will write on the board decimal number and equivalent to binary number using conversion table
   1. 0=0000
   2. 1=0001
   3. 2=0010
   4. 3=0011
   5. 4=0100
   6. 5=0101
   7. 6=0110
   8. 7=0111
   9. 8=1000
   10. 9=1001
5. I will explain the step with example to convert (5674)₁₀=(?)₂
   1. Divide the given number system by 2.
   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.
