Make the see-saw level.

For grown-ups

A see-saw tips down on the heavier side. Your child taps the block that makes both sides the same — the very first feel of what equals means (the seed of algebra). It reads every prompt aloud, the blocks are big to tap and easy to count, and there is no way to lose — a wrong tap just says "try another." No timer, no score. Everything stays on this device.

The see-saw friends

Teeter — feels which side is heavier and tips the see-saw down.
Evenly — makes it level: the same amount on both sides.
Wobble — it's okay to try another block; you can't lose here.
Balley — the balance keeper: when both sides match, it's level.

Painted friends + storybooks are coming soon.
