FOREST RESIDENTS

The Seven Residents of the Forest

MOMOMORI ADVENTURES

Every product is a quest letter from the forest 🍂

Not “math games”, not workbooks. The residents are in trouble and need your child's help — the learning hides inside the story.

Momo'S QUEST

Number Kingdom: Defend the Castle

Wraps addition, subtraction, comparison, and strategy inside a “rock-paper-scissors → attack & defend castles” battle loop. Hold your own castle, topple theirs with quick mental math — a round takes under 10 minutes, comebacks are possible, and kids spontaneously shout “one more round.”

Dudu'S QUEST

A Child's Number Observation Diary V2

A diary of experiments for growing self-directed learning through play. Not a workbook — a guide that takes a child into the real world to discover the numbers already hiding there, and draw what they find. The second edition is finalized, and connected to the Number Kingdom game system.

Meta'S QUEST

Goodnight Forest (dreaming)

Ten minutes before bed: patrol the forest with Meta and his glowing leaf, tucking today's feelings into a dream, one by one.
