2016 Alternative Assessment Practice

This is a Practice task for the upcoming alternative assessment.

The submission date for the actual Viva Voce is Wednesday 1 Feb 2016, 2359 hours.
The task is compulsory, and you are to submit your work via the platform instructed by your teacher.

Topic: Number systems

To demonstrate your understanding of the concepts and calculations through clear articulation and presentation of problem solving.

Instructions (I):
• This is an individual task. Complete the viva voce practice on your own.
• This is a reinforcement of similar questions based on the topic covered in class.
• It will also help you to seek and articulate your understanding of concepts as you attempt to explain your approach and solution to the problem.
• You should not take more than 1 hour to complete the entire task.
Note:
You will need to record your work and submit via Google Classroom (Mathematics)

Instructions (II):

1. Add up the last 5 digits of your NRIC number. This 2 digit number “XX” is what you will convert from a decimal system to a binary system.
2. DO NOT RECITE OUT YOUR ENTIRE NRIC NUMBER ON THE VIDEO FOR SECURITY REASONS. You only need to state the last 5 digits on video.
3. Using your birthdate “YY” as another 2 digit number, explain how you will perform the simple arithmetic operation “XX + YY” in binary system.
• Research on how to count in binary system using the digits “0” and “1”.
• Explain briefly, in your own words, on how a binary system works. You may choose to use any visualisation tools to help explain yourself.
• Work out and explain the solution clearly. You may choose to write it out, or use various software like Numbers to write your own script.
• Do not simply read out the lines of the working. Instead, inform the audience:
• how you identify the key information
• why you choose a particular method to solve the problem
• explain how the method works
4. Recording
• You may use QuickTime Player, PhotoBooth or any other suitable media to record your viva voce.
• Here are some ways that you can present your worked solution:
