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

Peanut Butter and Jelly Algorithm / Sequencing Activity
Teach ALGORITHMS AND SEQUENCING. Students will "code" a set of instructions, the algorithm, to help a robot, yourself, make peanut butter and jelly sandwiches. Students will create their own algorithm for the robot to use and make a sandwich. They have two tries! Usually the first try is going to messy and fun as the teacher/robot tries to follow the steps. Once they learn from their mistakes (debugging) they can try again, usually with better results. SLIDES 1 - 5 ARE TEACHER INSTRUCTIONSSLIDES

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
