Color me green. The fourth lesson in a unit of 15 introduces the class to color images and how to encode color images using binary code and hexadecimal numbers — and they will quickly notice that it is easier to code the color for each pixel. After learning how to use the tools, each individual creates a personal favicon to use throughout the rest of these computer science lessons.

Instructional Ideas

• Have pupils design their favicon on graph paper and then encode it using the Pixelation Widget
• Use the optional hexadecimal numbers activity so the class better understands hexadecimals prior to trying to coding their favicon

Classroom Considerations

• Get familiar with the pixelation tool in order to present it in an interactive way

Pros

• The lesson plan contains links to tutorial videos on how to use the widget
• The rubric comes with reflection questions about the project
• Contains a content corner that makes the distinction between mixing paint and mixing RGB lights to make colors

Cons

• None
