Lesson 1 — Linear Search and Counting Steps
⏱ 30–40 minutes 💻 Write real Python in the browser
💡 Algorithms are judged by step count, not by feel — linear search grows step-for-step with the data
👨👩👧 Notes for parents
Level: Master — roughly Grade 9 / ages 14–15 Duration: 30–40 minutes Format: Write real Python in the browser Concept: Algorithms are judged by step count, not by feel — linear search grows step-for-step with the data
Learning Objective
Kids write a linear search with a step counter and explain what happens to the count when the data doubles.
Do It Together (Parent-Child Co-participation)
Play it out: hide one object among 8 drawers and count how many a searcher opens — on average about half of them.
