JarPals
How many beans in the jar? Guess first - a good guess isn't luck, it uses a benchmark (about ten fit in a scoop, the jar looks like about four scoops, so about forty). Then COUNT to check: line the beans up in tens (four tens and two more is forty-two) and see how close your guess was on a number line. A tiny, gentle estimation game, no internet. Ages 6-8.

Meet the cast
JarPals's crew ARE the steps of a good estimate - the cast IS the curriculum: guessing with a reason, then counting to check. Scoopy always finds a benchmark first (about ten beans fit in one scoop). Guess uses that benchmark to make a smart estimate, not a wild one: about how many scoops is the jar? Tenny lines the beans up in groups of ten so they are easy to count and hard to lose your place in. Checker puts the guess and the real count side by side on a number line - how close were we? Beans, the mentor, reminds everyone of the two rules that matter: a good estimate uses a benchmark, and counting in tens is faster and surer than counting one by one. A first, gentle feel for estimation and benchmark counting (6-8): short words, big buttons, no score. Painted portraits are a tracked follow-on (R-WEB-CLONE-SPAWN-TRACKED); a text-only crew + a flat, deterministic on-device estimation engine ship now - nothing leaves the device.
Scoopy
The benchmark-finder - about ten beans fit in one scoop, the reference a good estimate is built on
Guess
The estimator - uses the scoop benchmark to guess about how many, a smart estimate rather than a wild one
Tenny
The counter - lines the beans up in groups of ten so the count is fast and you never lose your place
Checker
The one who compares - puts the guess and the real count side by side on a number line to see how close
Beans
(Mentor) The guide who insists on the two rules: estimate with a benchmark, then count in tens to be sure
