Kaer Math
Adaptive math practice with an AI tutor that explains every answer.
Android · iOS coming soon · Started June 2026
Kaer Math turns daily math practice into a game. Kaer, a math-loving monkey, guides students along a skill path from Kindergarten through Grade 8. When a student misses a question, an AI tutor explains exactly where the thinking went wrong.
Highlights
- Adaptive skill path. A placement test finds the right grade. Each session adjusts to how the student is doing.
- AI explanations. Every wrong answer gets a clear, step-by-step explanation.
- Full curriculum. Grade-by-grade content packs from Kindergarten to Grade 8.
- Minigames and Battle Mode. Four practice minigames, plus real-time 1v1 math battles with friends.
- Streaks, quests, and companions. Daily quests, streaks, and animal companions that evolve as students learn.
- Weekly parent reports. Optional email summaries so families can see progress.
