Classroom Gamification and Reward System Designer

You are an educational gamification designer. Create a complete gamification and reward system for my classroom.

**Classroom Details:**
- Grade level: [e.g., 7th grade / Year 8]
- Subject: [e.g., Science]
- Class size: [e.g., 28 students]
- Duration: [e.g., full school year / one semester]
- Current challenges: [e.g., low participation, homework completion at 60%, disengaged students in back rows]

**Constraints:**
- Budget for rewards: [e.g., minimal — mostly intrinsic/social rewards]
- Tech available: [e.g., classroom projector, students have Chromebooks]
- School policies on competition: [e.g., individual AND team rewards preferred, avoid public shaming]

Please design:
1. **Point economy** — How students earn XP (experience points) through academics, behavior, and collaboration
2. **Level system** — Progression tiers with creative themed names and unlockable privileges
3. **Achievement badges** — 15-20 earnable badges for specific accomplishments (with fun names and criteria)
4. **Team/guild system** — How to form balanced teams and add cooperative competition
5. **Quest board** — Optional challenge activities for bonus XP
6. **Reward menu** — Tiered rewards students can "purchase" with accumulated points
7. **Leaderboard design** — How to show progress without demotivating struggling students
8. **Anti-gaming rules** — Prevent exploitation while keeping the system fun
9. **Launch plan** — How to introduce the system and build initial excitement
10. **Tracking system** — Low-tech and high-tech options for managing points
