Die DVD beschäftigt sich mit:
1. Addieren gleichnamiger Brüche

1.3 Addieren am Beispiel
1.4 Was bedeutet »gleichnamiger« Bruch?
1.5 Was sind »ungleichnamige« Brüche?

2.2. Erweitern auf den gemeinsamen Nenner
3. Subtrahieren gleichnamiger und ungleichnamiger Brüche
3.1 Vergleich mit der Addition
Das Subtrahieren von Brüchen funktioniert wie das Addieren, nur dass wir jetzt die Zahlen nicht zusammenzählen, sondern abziehen.
3.2 Subtraktion beliebiger Brüche
Gemeinsam mit den umfangreichen Arbeitsblätter ist die DVD sehr gut zum
Einsatz im Unterricht geeignet.

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Tolerance
“Tolerance means being generous and kind to other people and helping them, too.”
The Daily Newspaper
Every day, there is a surge of news reaching us via different news channels. In spite of TV and Internet, the daily paper still is one of the most important main sources of news. But how is a newspaper created? The film shows the production of a paper in the course of one day. Starting with the editorial meeting in the morning, in which the topics and deadlines are determined, the film accompanies a journalist during her research work. You can see how a journalistic interview is conducted and what the photographer must consider when taking a press photo. Back in the editorial office, the editor’s work is illustrated, which includes the page layout and the writing of an online article in today’s time. Impressive pictures from the printing centre depict the process from the digital page to the finished newspaper. Together with the comprehensive accompanying material, the DVD is perfectly suited for use at school
