KEMIplay - MathWorld

Build cozy worlds, solve playful math vaults, and grow a mascot companion while practicing curriculum-based math for grades 1–9.

MathWorld turns math practice into a playful world-building adventure.

Designed for children in grades 1–9, MathWorld helps learners practice key math skills through short, game-like challenges instead of long worksheets. Children build and repair themed worlds, gather resources, solve puzzle vaults, and care for a friendly mascot companion as they grow.

Inside MathWorld, children can:

• Solve interactive math vaults and puzzles • Practice age-appropriate skills across number sense, arithmetic, fractions, geometry, logic, and more • Build and expand themed worlds such as Space and Cloud • Earn resources through progress and use them to develop their world • Collect trophies for achievements • Grow alongside a friendly mascot companion • Decorate a personal ChildHome with unlocked items • Learn through small, repeatable moments that fit naturally into play

MathWorld is built around the idea that children learn best when practice feels meaningful. Instead of separating “learning time” and “game time,” the game connects math tasks to visible progress, rewards, and cozy world-building.

The goal is not pressure, punishment, or streak anxiety. Children are encouraged to try, improve, and keep going. Progress is designed to feel warm, safe, and motivating.

For parents and teachers, MathWorld is being built as a long-term learning companion: a place where math practice can become part of a child’s daily routine while still feeling like a game they want to return to.

Build your world. Solve the vaults. Grow your mascot. Practice math through play.
