K–12 math learning app
Kaer Math builds a personalized world path from a placement test, then adapts every day — warmups, weak-skill fixes, new topics, or mastery when they’re ready. Kaer, a sarcastic-but-warm monkey in a graduation cap, keeps them moving.
Free for every grade and topic. Pro is optional.
How it works
Four steps. Tap a phone to expand it, or More info for the details.
A short adaptive check finds the right starting grade band — not a one-size “start at page 1.”
Four worlds — Explorer, Adventurer, Champion, Master — each covering a grade band. Inside every topic: stepping-stone lessons plus a mastery test.
The engine watches per-skill hit rates and recommends what to do next: warmup, fix a weak skill, push a new topic, or sit a mastery test.
Nine grade animals, each with its own evolution cinematic. Progress feels like collecting — because it is.
Inside the app
Tap recommendation chips, animals, or phones for more.
Behind the path, Kaer Math tracks hit rates per skill. Recommendations shift: warmups when they’re rusty, targeted fixes when a skill is weak, new topics when they’re ready, mastery tests when confidence is earned.
Explorer → Adventurer → Champion → Master. Each world is a grade band. Every topic is a trail of stones ending in a mastery check — so kids always see where they are and what’s next.
Nine grade companions, each with staged evolutions and a cinematic payoff. The collection isn’t fluff — it’s the scoreboard kids care about. Tap any animal.
A daily logic puzzle, quests to clear, streaks with freeze items when life happens, and a Spark Store for cosmetics. Structure for the day — rewards for showing up.
