About BoneTots
BoneTots is a skeleton builder + size game for the youngest learners, inspired by the giant skeletons in a natural-history museum's fossil hall.
Why bones?
Bones are perfect for a young scientist: they are inside every animal (and inside you), and each one has a clear job. Building a skeleton one bone at a time — and hearing what each bone does — is a first taste of structure and function. Then, measuring a huge dinosaur in “kids long” turns a scary-big number into something a child can feel in their own body.
