Comparative size concepts built for the very youngest players
Big & Small Sort is a size comparison game for preschoolers and kindergartners built around the same simple two-tap loop as the rest of the site's sorting games: tap a shape, then tap the labeled bin it belongs in. A correct match sorts the shape away with a little celebration and a new one takes its place; a wrong bin just wobbles the shape for a moment with no penalty at all, so a child can try the other bin until they find the right one.
Three tiers cover three different comparative ideas that early math and language both depend on. Tier 1 sorts circles by overall size into Big or Small, the most basic comparison. Tier 2 sorts tall and short bars by height into Tall or Short, a comparison along a single dimension rather than overall size. Tier 3 sorts circles by how much of them is filled in, Full (a solid color) or Empty (just an outline), a comparison most sorting games never attempt but one that shows up constantly in everyday language.
Every few sorted shapes earns a star, so there is a real sense of progress alongside the simple mechanic. Big & Small Sort is free, works with a mouse, touchscreen, or keyboard, needs no download or account, and saves progress locally in your own browser, which also makes it school-safe on a shared classroom device.

Frequently asked questions
How do I play Big & Small Sort?
Tap a shape to pick it up, then tap the bin it belongs in. A correct match sends it into the bin with a little celebration; a wrong bin just wobbles the shape so you can try the other bin.
What comparisons does it cover?
Tier 1 sorts circles into Big or Small, Tier 2 sorts bars into Tall or Short, and Tier 3 sorts circles into Full (solid color) or Empty (outline only).
Is there a penalty for choosing the wrong bin?
No. There is no wrong-answer screen, lost life, or timer. The shape just wobbles for a moment and stays on the board until it's sorted into the correct bin.
What ages is Big & Small Sort good for?
Roughly ages 3 through 6. Big vs Small is the easiest starting comparison for toddlers and preschoolers, and Tall vs Short and Full vs Empty suit kindergartners building broader comparative vocabulary.
