Mean & Median Balance: Mean Game for Grades 6‑7
Slide the pivot to the balance point, then see what an outlier does.
A beam holds a set of weights. Slide the pivot to the mean so the beam balances, slide a flag to the median, and predict whether the mean or the median moves more when a new weight drops in. Three levels take you from whole-number means to half-step means and outliers.

What kids practise
Mean & Median Balance gives students repeated, low-pressure practice with mean, median, measures of center, balance point, outliers, and data sets. It is written for grades 6-7, with levels that let younger and older players start at the right difficulty. Every question is generated fresh, so a replay is never the same, and a wrong answer shows the correct one so the round teaches as well as tests.
How it plays
Controls: Drag the pivot or use the slider (Left/Right arrows, or the minus and plus buttons), then press Enter to check. On outlier questions press 1, 2 or 3 or tap an answer. P pauses, M mutes.
It works with a keyboard, a trackpad or a touch screen, so it runs on school Chromebooks, tablets and phones.
