[b]Die Lernumgebung ist konzipiert als Lernbegleiter für den traditionellen Unterricht mit Phasen entdeckenden Lernens in digitaler Form (Unterrichtskonzept: Entdeckendes Lernen mit mathematischer Kommunikation + Differenzierung + Feedback). [/b] Hinweis: Bei Übungsaufgaben mit anschließendem Textfeld sind die Schülerinnen und Schüler gehalten, die Aufgabe schriftlich (z.B. im Heft) anzufertigen. Mit Hilfe des Textfeldes (ein Buchstabe muss eingetragen werden, dann wird der Button „Antwort überprüfen“ aktiviert) kann die Lösung überprüft werden.
