📝 Notes & Lessons
📱 Mobile Design Notes
This lesson is optimized for mobile-first learning. Touch targets are 48px minimum. Animations use 700ms for removal (slower than addition's 500ms) to let children observe what's "going away."
UX Principle • Touch-friendly
🎨 Visual Language
Subtraction uses rose/red tones (--subtract: #E11D48) to differentiate from addition's green theme. This color coding helps children recognize operation types at a glance.
Design System • Color Semantics
🗣️ Bilingual Support
English and Hindi dialogue maintains story continuity. Riya speaks English while Arjun reinforces concepts in Hindi. Voice synthesis uses appropriate language detection.
Accessibility • Language Support
🧠 Pedagogical Approach
Symbols appear AFTER physical manipulation. Children experience "taking away" through tapping before seeing − and = symbols, building concrete understanding before abstract notation.
Learning Theory • Concrete to Abstract
📊 Progress Tracking
The practice zone tracks correct/total attempts. Quiz provides empathetic explanations for wrong answers. Certificate celebrates completion regardless of score.
Gamification • Positive Reinforcement
