Toybox Math is a browser math game for kids ages 5–8 that turns the child's own world into the game board. A child uploads a photo of their favorite stuffed animal, and Meta's SAM 3.1 cuts it out to become their personal companion throughout the adventure. From there, the real objects on their table — blocks, fruit, toys, Lego bricks — become the math pieces. SAM 3.1 segments and counts those objects for counting, addition and subtraction to 20, comparison, ratios, and early fractions, while Muse Spark 1.3 generates a personalized, cached story pack around their toy so play never waits on a model call. The problem it solves: Early math is usually taught with worksheets and generic on-screen sprites. The numbers feel abstract, disconnected from anything a child can touch, and easy to disengage from. Toybox Math makes math tangible: the toy they already love is the avatar, their table is the level, and the objects they can hold in their hands are the problem. It is designed for young learners with no fail states, no timers, and no lives to lose — a wrong answer brings a helpful hint and another try. Read-aloud, still-target, and manual-count options let children play in different ways. Built with SAM 3.1 + Muse Spark 1.3. Live at https://toybox-math.pages.dev/
