Bruchrechnen I
Addition und Subtraktion
Die DVD beschäftigt sich mit:
1. Addieren gleichnamiger Brüche
1.1 Zähler und Nenner
Wie rechnet man mit »gebrochenen« Zahlen, mit »Brüchen« also?
Am einfachsten ist die Addition sogenannter gleichnamiger Brüche.
Das sind Brüche, die denselben Nenner haben
1.2 Erste Schritte am Beispiel
1.3 Addieren am Beispiel
1.4 Was bedeutet »gleichnamiger« Bruch?
1.5 Was sind »ungleichnamige« Brüche?
2. Addieren ungleichnamiger Brüche
2.1 Zähler und Nenner
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.

Inclusion
Madita is eleven and blind. She does not want to go to a special school but to a regular grammar school. She says she feels "normal" there. Jonathan is eight and has a walking disability. He likes going to the school where he lives. Here, his best friend sits next to him. Max Dimpflmeier, a teacher who is severely deaf, explains that school life is not easy. Quote Max Dimpflmeier: "You don't want to attract attention, you want to avoid saying that it is necessary for you that 70 people adjust to your situation." People on their way to inclusion.
Youth Movement
Dancing until your feet hurt: Here, at the meeting on the Hoher Meissner near Kassel, 3,500 participants from Boy Scout associations, youth and Wandervogel groups from all over the German-speaking region have gathered. They want to celebrate, simply get to know each other and commemorate a historic anniversary.
Internet Addiction
The film consists of two parts. The first part is the 15-minute short film “In the Net”. It describes the problem of excessive Internet use in a humorous way, in particular the risk of losing touch with reality when chatting. The second part illustrates with three real persons how Internet addiction can develop and the problems encountered by those who are afflicted. The authentic statements are commented by an experienced therapist. For many pupils, the issues addressed here are related to their everyday lives. What is a “sensible” use of the Internet, where does pathological addiction start? In contrast to addiction to alcohol, nicotine or drugs, the public seems to be largely ignorant of the problem of this addiction, which is not related to any substance abuse. The film provides material for discussion in the classroom (crossdisciplinary) and can be used as a basis for the formulation of prevention strategies.
