Free only in November. This is a virtual manipulative to support developing number sence and arithmetic concepts. Watch a video of the app: http://www.youtube.com/watch?v=9bPtA8lkXt4 Two (sub-)quantities together result in a new total quantity. This is called addition. And if you take away a subquantity, another subquantity remains. This is called subtraction. With this virtual manipulative kids kann explore and learn the relationsships between subsets and total sets. This is how it works: Touch the screen with your fingers to produce token. You can also move these tokens with your fingers. Move the tokens out to the top to delete it. Tap on a number to sort the token. Spipe over a number to hide it or to show it again. Pull down the shutters to hide one half of the tablet. Shake the tablet to empty it. The basic operations addition and subtraction are based on the concept that a quantity can be split into subsets and you can join the subsets again (part-whole concept). If kids understood the relationsship beetween partial and total quantities, an essential cornerstone has been laid for successful mathematical learning. This virtual manipulative is an tool to explore and experience these concept. This app does not include tasks. For successfull and effective learning kids use this app to solve tasks that callange them to experiment and reflect. Here are some examples: How can I quickly produce 8 token with my fingers? How do I have to sort the tokens to see the number without counting? On one side there are 4 token, on the other side 3 token. How many token are this in total? What happens, if I move 1 (2, 3, ...) token from one side to the other? What happens, if I remove 1 (2, 3, ...) token from the tablet? How many configurations are possible to split 10 token on the two sides? On one Side of the tablet are 3 token. How many token do I have to put on the other side to have 7 token in total? On the tablet are 10 token. You can only see a part of it. How many token are hidden? I put 8 token on one side of the tablet. Then I take 5 token to the other side. How many token are left?

Die App Kombi ermöglicht Lernenden der Grundschule und Sekundarstufe I, kombinatorische Problemstellungen digital materialgestützt zu lösen. Mit der Funktion 'Arbeitsmittel' kann Kombi für die Bearbeitung von Aufgaben aus Schulbüchern und anderen Quellen genutzt und mittels der Funktion ‚Aufgaben‘ können voreingestellte kombinatorische Aufgabenstellungen auf verschiedenen Schwierigkeitsgraden gelöst werden. Zusätzlich besteht für die Lehrkraft und für Lernende die Möglichkeit, Aufgaben in Kombi selbst zu erstellen bzw. an die Lerngruppe anzupassen. Die erstellten Aufgaben können per QR-Code bereitgestellt und anschließend von anderen Nutzenden eingescannt und gelöst werden. Lösungen zu kombinatorischen Problemstellungen können in Kombi durch das Erstellen von Objekten (z.B. Türmen, Eiswaffeln etc.) oder eines Baumdiagramms probierend oder zunehmend systematisch gefunden werden. Die Objekte können im Lösungsprozess einzeln oder mittels Markierung durch das Lasso gemeinsam bewegt, Handlungen rückgängig gemacht oder wiederholt und Objekte gelöscht werden. Das digitale Spielfeld kann dabei gezoomt werden, so dass auch größere Objektmengen gut sichtbar sind. Zudem stehen „Strategiemakros“ bereit, die es ermöglichen, dass strategische mentale Operationen wie beispielsweise „erst alle Türme mit Gelb oben“ direkt in eine digitale Handlung übersetzt werden können.
