1. NEW INFORMATION - Flipped lesson

Watch the following clips at home prior to the lesson. Take notes where appropriate and answer the questions:

• Binary Numbers (5 min) 
• Computer Tutorial How Binary Code Works (7 min).
• How Computers Work: Binary & Data (6 min).

1. Why do we use a Base 10 number system? Give an example.
2. Calculate the number value of the following binary number 1001101.
3. Represent the number 212 using binary numbers.

2. GOAL  Computing is essentially based on binary code and logic gates. 

3. ACCESS PRIOR KNOWLEDGE  

Discuss the following questions: 

1. How does binary code enable the operation of technological devices ranging from calculators to high powered supercomputers?
2. What advantages does binary code have over the decimal system that enables it to be used in the information technologies?

Test your binary knowledge here.

3. NEW INFORMATION

Watch the Fundamentals of Computing  presentation and discuss with your teacher if necessary. Summarise the slides in your workbook.

4. APPLICATION TASK

(20 mins) 

Complete the  Fundamentals of Computing activities:

Additional information is available at:

How Bits and Bytes Work (How Stuff Works) 

5. GOAL REVISITED

(5 mins) 

Pair and share with another student what you have learnt from the activity. The discussion needs to focus on why the use of binary code, as complex as it might seem for us humans, is actually a useful way for a computer to send and receive information.

6. EXTENSION ACTIVITIES

(optional)
