Intro to CS — Lesson 1.3: Algorithms and Instructions
Help students understand one of the most important foundations of computer science: algorithms. In this lesson, students learn what an algorithm is by writing clear, step-by-step instructions for real-world tasks and analyzing why precision and order matter when communicating with computers. Through hands-on examples and guided reasoning, students discover that computers follow instructions exactly and cannot “guess” intent. This lesson builds directly on Lesson 1.1 (What Is Computer Science

Programming Jigsaw Puzzle Activity
Bring algorithms to life with this interactive, unplugged classroom activity! In this collaborative lesson, students work in groups to solve a physical puzzle — but before they start, they must write and follow their own pseudocode algorithm. As they work, they’ll experience firsthand how sequencing, selection, and iteration apply to problem-solving in computer science. Afterward, students reflect on their “debugging” process and connect their experience to real programming concepts. 🧠 St
