Summary

[edit]
Description
Deutsch: Insgesamt 32,6 Gramm orangene Knet: mit der Goldwaage soll sie in drei gleich große Stücke aufgeteilt werden. Die Waage zeigt nur an, ob zwei Stücke gleich schwer sind. Je nach gewählter Strategie benötigen Kinder zwischen 10 bis fast 40 Minuten, um hier zum Ziel zu kommen. Dieser Versuch ist recht beliebt bei älteren Grundschülern und später bis zur Klasse 7. Im Zusammenhang mit Dyskalkulie hat sie sich der Versuch bewährt um die Idee der Mengenkonstanz zu klären. Die Aufnahme entstand in der Mathe-AC Lernwerkstatt Mathematik in Aachen.
