See-Saw Game: Finding the Mean

① This interactive see-saw game demonstrates the concept of arithmetic mean through a physical balance metaphor, where students adjust data values to achieve equilibrium on a lever, linking statistics to physics. ② Core mathematical concepts include arithmetic mean (average), data distribution, and the lever principle (moment balance), with connections to histograms, rotation, and reflection. ③ Construction uses GeoGebra commands: Random, Unique, Length, Polygon, Textfield, Sequence, Rotate; objects include valueend, valuestart, nend, nstart, n, entry, ans, e, F, size, nfinal, B, pic1, v1, v2, v3, C, D, E, poly3, e_1, c_1, d_1, inputBox1, button1, button2, polygonlist, button3, polyfinal, a, b, c, d, angle, and their variants, enabling dynamic data generation, interactive input, and visual feedback. ④ Suitable for middle school to high school students learning statistics and averages, as well as for interdisciplinary STEM lessons combining mathematics and physics, promoting kinesthetic and inquiry-based learning.
