Eksperymentujemy tu z różnymi interakcjami i sposobami pokazywania matematyki na ekranie dotykowym. Szukamy tego, co naprawdę pomaga zrozumieć temat.

To strefa eksperymentów — rzeczy tu mogą działać dziwnie, znikać albo zmieniać się z dnia na dzień.

Pencil canvas drawing

Drag & drop — number line

Drop fraction markers onto a 0–1 number line. Compare freeform position vs snapped to nearest 1/8 tick.
