binary and pixel

1. LESSON 5: Binary and pixels UNIT 1: BINARY AND ONLINE GRAPHICS

2. Learning Objective: To understand how binary used to represent pixels. To demonstrate how to create a simple graphic using binary sequence.

3. Starter activity LO: To understand how binary used to represent pixels How does the Hubble Space Telescope get images to Earth when it is so far in space?

4. Main teaching: Binary Transmission Binary transmission format begins with representing information in a digital form, typically using binary digits (0s and 1s). LO: To understand how binary used to represent pixels

5. Main teaching: Binary and pixels LO: To understand how binary used to represent pixels Consider, a simple black and white bitmap image with a low resolution . Each pixel can be represented in binary with either a 1 (black) or a 0 (white)

6. ACTIVITY 1 - Complete the binary table that represent the simple graphic LO: To understand how binary used to represent pixels

7. Binary word? A binary word of length n is a string of n binary digits, or bits. For example, there are 8 binary words of length 3, namely, 000, 100, 010, 001, 110, 101, 011 and 111. LO: To demonstrate how to create a simple graphic using binary sequence.

8. PLENARY QUESTIONS Match the binary to the image The PowerPoint is interactive. If you make the PowerPoint full screen you can click on the images to show what each one is. LO: To demonstrate how to create a simple graphic using binary sequence.

9. Success criteria I know binary is used to represent pixels. I can create a simple bitmap and show the binary sequence that created it.
