Bubbles

iOS game that taught kids multiplication through play — popping number bubbles to build fluency. PM at a NYC edtech startup.

An iOS game designed to make multiplication practice feel like play. Kids popped bubbles with numbers to solve multiplication problems, with adaptive difficulty that met each student where they were. Built as PM at a small NYC edtech startup focused on elementary math.

The game used spaced repetition principles — facts a student struggled with appeared more frequently — wrapped in a game mechanic that felt rewarding rather than remedial. We tested with classrooms in NYC public schools and saw measurable improvements in multiplication fluency after 4-6 weeks of regular play.
