Snowflake Algorithm Lesson Pack: Unplugged Coding & Debugging Activity
Tired of abstract programming lessons that leave students confused about what an "algorithm" actually is? Turn coding concepts tangible with a paper-snowflake unplugged activity that makes algorithms, precision, iteration, and debugging visible and memorable. You know the struggle: students can recite definitions but still can't write instructions someone else can follow. This resource fixes that by putting students in the role of both designer and computer — they must write exact, repeatable

Applied AI Classroom | Unit 4:Coding, Algorithms, AI Thinking | 4 Wks | Gr.11-12
Unit 4 is the technical unit of the Applied AI Classroom course — the point where students stop describing AI and start creating code similarly to the engineers who build AI. Week 1 covers algorithms: what makes a set of steps precise, finite, and unambiguous, how binary search works, how to write pseudocode, and how to draw flowcharts. Week 2 introduces Python fundamentals — variables, data types, conditionals, loops, and functions — with no prior coding experience assumed. Week 3 teaches stu
