TeeterTots
A see-saw tips down on the heavier side — tap the block that makes it level. TeeterTots says everything out loud (no reading needed), the blocks are big to tap and easy to count, and there is no way to lose — a wrong tap just says "try another." Balancing the see-saw is the first taste of what equals means (the seed of algebra). On-device, no account. Ages 3–5.

Meet the cast
TeeterTots' see-saw friends each embody one move of BALANCE — the crew IS the idea: Teeter feels which side is heavier, Evenly makes both sides the same, Wobble reminds you it is okay to try another block (you cannot lose). Mentor Balley keeps the balance idea: when both sides match, it is level — the very first feel of what equals means. Painted portraits + storybooks are a tracked follow-on (R-WEB-CLONE-SPAWN-TRACKED); a text-only crew + a flat clean see-saw manipulative ship now, audio-first for pre-readers.
Teeter
Feels which side is heavier and tips the see-saw down — more on one side makes that side go low
Evenly
Makes it level — the same amount on both sides means the see-saw balances (equal)
Wobble
It is okay to try another block — a wrong tap is never a loss, just try again
Balley
(Mentor) — when both sides match, it is level; that is the very first feel of what equals means.
