2-bit Binary Image Pixel Representation - Lesson, Guided Notes, HW (No Prep!)
No Prep! In this lesson, students explore how 2-bit binary representation allows for greater image detail by introducing multiple tones (white, gray, and black). Students compare 1-bit and 2-bit encoding, then apply their understanding through hands-on activities where they create and decode pixel art using 2-bit binary values. The lesson emphasizes the value of binary in digital image processing and encourages reflection on how increasing bits enhances image quality. Includes: Lesson (Google Sl

1-bit Binary Image Pixel Representation-Lesson,Guided Notes,Practice (No Prep!)
No Prep! Keys Included This lesson introduces students to how computers represent black and white images using binary code. Through interactive activities, students learn that each pixel in an image can be represented by a 1 (black) or 0 (white), and how these values are arranged in a grid to form digital pictures. They practice encoding and decoding images using binary numbers and also explore how to convert binary rows into decimal values. The lesson combines math, technology, and creativity t
